GENERAL DESCRIPTION

ADSP-BF539/ADSP-BF539F
The ADSP-BF539/ADSP-BF539F processors are members of the Blackfin Devices, Inc./Intel Micro Signal Architecture (MSA). Blackfin processors combine a dual-MAC, state-of-the-art signal pro­cessing engine, the advantages of a clean, orthogonal RISC-like microprocessor instruction set, and single-instruction, multi­ple-data (SIMD) multimedia capabilities into a single instruction set architecture.
The ADSP-BF539/ADSP-BF539F processors are completely code compatible with other Blackfin processors, differing only with respect to performance, peripherals, and on-chip memory. These features are shown in Table 1.
By integrating a rich set of industry-leading system peripherals and memory, Blackfin processors are the platform of choice for next generation applications that require RISC-like program­mability, multimedia support, and leading edge signal processing in one integrated package.

LOW POWER ARCHITECTURE

Blackfin processors provide world class power management and performance. Blackfin processors are designed in a low power and low voltage design methodology and feature dynamic power management, the ability to vary both the voltage and fre­quency of operation to significantly lower overall power consumption. Varying the voltage and frequency can result in a substantial reduction in power consumption, compared with simply varying the frequency of operation. This translates into longer battery life and lower heat dissipation.

SYSTEM INTEGRATION

The ADSP-BF539/ADSP-BF539F processors are highly inte­grated system-on-a-chip solutions for the next generation of industrial and automotive applications including audio and video signal processing. By combining advanced memory con­figurations, such as on-chip flash memory, with industry­standard interfaces with a high performance signal processing core, users can develop cost-effective solutions quickly without the need for costly external components. The system peripherals include a MOST Network Media Transceiver (MXVR), three UART ports, three SPI ports, four serial ports (SPORT), one CAN interface, two 2-wire interfaces (TWI), four general-pur­pose timers (three with PWM capability), a real-time clock, a watchdog timer, a parallel peripheral interface, general-purpose I/O, and general-purpose flag pins.

ADSP-BF539/ADSP-BF539F PROCESSOR PERIPHERALS

The ADSP-BF539/ADSP-BF539F processors contain a rich set of peripherals connected to the core via several high bandwidth buses, providing flexibility in system configuration as well as excellent overall system performance (see Figure 1 on Page 1). The general-purpose peripherals include functions such as UART, timers with PWM (pulse-width modulation) and pulse measurement capability, general-purpose flag I/O pins, a real­time clock, and a watchdog timer. This set of functions satisfies a wide variety of typical system support needs and is augmented by the system expansion capabilities of the device. In addition to these general-purpose peripherals, the processors contain high speed serial and parallel ports for interfacing to a variety of audio, video, and modem codec functions. An MXVR trans­ceiver transmits and receives audio and video data and control information on a MOST automotive multimedia network. A CAN 2.0B controller is provided for automotive control net­works. An interrupt controller manages interrupts from the on­chip peripherals or external sources. And power management control functions tailor the performance and power characteris­tics of the processor and system to many application scenarios.
All of the peripherals, GPIO, CAN, TWI, real-time clock, and timers, are supported by a flexible DMA structure. There are also four separate memory DMA channels dedicated to data transfers between the processor’s various memory spaces, including external SDRAM and asynchronous memory. Multi­ple on-chip buses running at up to 133 MHz provide enough bandwidth to keep the processor core running along with activ­ity on all of the on-chip and external peripherals.
The ADSP-BF539/ADSP-BF539F processors include an on-chip voltage regulator in support of the processor’s dynamic power management capability. The voltage regulator provides a range of core voltage levels from V bypassed at the user's discretion.

BLACKFIN PROCESSOR CORE

As shown in Figure 2, the Blackfin processor core contains two 16-bit multipliers, two 40-bit accumulators, two 40-bit ALUs, four video ALUs, and a 40-bit shifter. The computation units process 8-bit, 16-bit, or 32-bit data from the register file.
The compute register file contains eight 32-bit registers. When performing compute operations on 16-bit operand data, the register file operates as 16 independent 16-bit registers. All operands for compute operations come from the multiported register file and instruction constant fields.
Each MAC can perform a 16-bit by 16-bit multiply in each cycle, accumulating the results into the 40-bit accumulators. Signed and unsigned formats, rounding, and saturation are supported.
The ALUs perform a traditional set of arithmetic and logical operations on 16-bit or 32-bit data. In addition, many special instructions are included to accelerate various signal processing tasks. These include bit operations such as field extract and pop­ulation count, modulo 2 and rounding, and sign/exponent detection. The set of video instructions include byte alignment and packing operations, 16­bit and 8-bit adds with clipping, 8-bit average operations, and 8­bit subtract/absolute value/accumulate (SAA) operations. Also provided are the compare/select and vector search instructions.
For certain instructions, two 16-bit ALU operations can be per­formed simultaneously on register pairs (a 16-bit high half and 16-bit low half of a compute register). By also using the second ALU, quad 16-bit operations are possible.

multiply, divide primitives, saturation
Figure 2. Blackfin Processor Core
The 40-bit shifter can perform shifts and rotates and is used to support normalization, field extract, and field deposit instructions.
The program sequencer controls the flow of instruction execu­tion, including instruction alignment and decoding. For program flow control, the sequencer supports PC relative and indirect conditional jumps (with static branch prediction), and subroutine calls. Hardware is provided to support zero over­head looping. The architecture is fully interlocked, meaning that the programmer need not manage the pipeline when executing instructions with data dependencies.
The address arithmetic unit provides two addresses for simulta­neous dual fetches from memory. It contains a multiported register file consisting of four sets of 32-bit index, modify, length, and base registers (for circular buffering), and eight additional 32-bit pointer registers (for C-style indexed stack manipulation).

combination with a hierarchical memory structure. Level 1 (L1) memories are those that typically operate at the full processor speed with little or no latency. At the L1 level, the instruction memory holds instructions only. The two data memories hold data, and a dedicated scratchpad data memory stores stack and local variable information.
In addition, multiple L1 memory blocks are provided, offering a configurable mix of SRAM and cache. The memory manage­ment Unit (MMU) provides memory protection for individual tasks that can be operating on the core and can protect system registers from unintended access.
The architecture provides three modes of operation: user mode, supervisor mode, and emulation mode. User mode has restricted access to certain system resources, thus providing a protected software environment, while supervisor mode has unrestricted access to the system and core resources.
The Blackfin processor instruction set has been optimized so that 16-bit opcodes represent the most frequently used instruc­tions, resulting in excellent compiled code density. Complex DSP instructions are encoded into 32-bit opcodes, representing fully featured multifunction instructions. Blackfin processors support a limited multi-issue capability, where a 32-bit instruc­tion can be issued in parallel with two 16-bit instructions, allowing the programmer to use many of the core resources in a single instruction cycle.
The Blackfin processor assembly language uses an algebraic syn­tax for ease of coding and readability. The architecture has been optimized for use in conjunction with the C/C++ compiler, resulting in fast and efficient software implementations.
ADSP-BF539/ADSP-BF539F

MEMORY ARCHITECTURE

The ADSP-BF539/ADSP-BF539F processors view memory as a single unified 4G byte address space, using 32-bit addresses. All resources, including internal memory, external memory, and I/O control registers, occupy separate sections of this common address space. The memory portions of this address space are arranged in a hierarchical structure to provide a good cost/per­formance balance of some very fast, low latency on-chip memory as cache or SRAM, and larger, lower cost and perfor­mance off-chip memory systems. See Figure 3.
The L1 memory system is the primary highest performance memory available to the Blackfin processor. The off-chip mem­ory system, accessed through the external bus interface unit (EBIU), provides expansion with SDRAM, flash memory, and SRAM, optionally accessing up to 132M bytes of physical memory.
The memory DMA controller provides high bandwidth data movement capability. It performs block transfers of code or data between the internal memory and the external memory spaces.

Internal (On-Chip) Memory

The ADSP-BF539/ADSP-BF539F processor has three blocks of on-chip memory, providing high bandwidth access to the core.
Rev. E | Page 5 of 60 | January 2011
Figure 3. ADSP-BF539/ADSP-BF539F Internal/External Memory Map
The first is the L1 instruction memory, consisting of 80K bytes SRAM, of which 16K bytes can be configured as a four-way set­associative cache. This memory is accessed at full processor speed.
The second on-chip memory block is the L1 data memory, con­sisting of two banks of up to 32K bytes each. Each memory bank is configurable, offering both cache and SRAM functionality. This memory block is accessed at full processor speed.
The third memory block is a 4K byte scratch pad SRAM, which runs at the same speed as the L1 memories, but is only accessible as data SRAM and cannot be configured as cache memory.

External (Off-Chip) Memory

External memory is accessed via the EBIU. This 16-bit interface provides a glueless connection to a bank of synchronous DRAM (SDRAM) as well as up to four banks of asynchronous memory devices including flash, EPROM, ROM, SRAM, and memory mapped I/O devices.

The PC133-compliant SDRAM controller can be programmed to interface to up to 128M bytes of SDRAM. The SDRAM con­troller allows one row to be open for each internal SDRAM bank, for up to four internal SDRAM banks, improving overall system performance.
The asynchronous memory controller can be programmed to control up to four banks of devices with very flexible timing parameters for a wide variety of devices. Each bank occupies a 1M byte segment regardless of the size of the devices used, so that these banks will only be contiguous if each is fully popu­lated with 1M byte of memory.

Flash Memory (ADSP-BF539F Only)

The ADSP-BF539F8 processor contains a separate flash die, connected to the EBIU bus, within the package of the processor.
Figure 4 shows how the flash memory die and Blackfin proces-
sor die are connected.
The ADSP-BF539F8 contains an 8M bit (512K × 16-bit) bottom boot sector Spansion S29AL008J known good die flash memory. Additional information for this product can be found in the Spansion data sheet at www.spansion.com. Features include the following:
• Access times as fast as 70 ns (EBIU registers must be set appropriately)
• Sector protection
• One million write cycles per sector
• 20 year data retention
The flash chip enable pin FCE AMS3–1 to AMS0
through a printed circuit board trace. When connected , the Blackfin processor can boot from the flash die.
When connected to AMS3–1

, the flash memory appears as non­volatile memory in the processor memory map, shown in
Figure 3.
Flash Memory Programming
The ADSP-BF539F8 flash memory can be programmed before or after mounting on the printed circuit board.
To program the flash prior to mounting on the printed circuit board, use a hardware programming tool that can provide the data, address, and control stimuli to the flash die through the external pins on the package. During this programming, V
DDEXT
and GND must be provided to the package and the Blackfin must be held in reset with bus request (BR
) asserted and a
CLKIN provided.
The VisualDSP++ tools can be used to program the flash mem­ory after the device is mounted on a printed circuit board.
Flash Memory Sector Protection
To use the sector protection feature, a high voltage (+8.5 V to +12.5 V) must be applied to the flash FRESET
pin. Refer to the
flash data sheet for details.

I/O Memory Space

Blackfin processors do not define a separate I/O space. All resources are mapped through the flat 32-bit address space. On­chip I/O devices have their control registers mapped into mem­ory mapped registers (MMRs) at addresses near the top of the 4G byte address space. These are separated into two smaller blocks, one of which contains the control MMRs for all core functions, and the other of which contains the registers needed for setup and control of the on-chip peripherals outside of the core. The MMRs are accessible only in supervisor mode and appear as reserved space to on-chip peripherals.
Figure 4. Internal Connection of Flash Memory (ADSP-BF539F8)
The Blackfin processor connects to the flash memory die with address, data, chip enable, write enable, and output enable con­trols as if it were an external memory device. Note that the write-protect input pin to the flash is not connected and inac­cessible, disabling this feature.

Booting

The ADSP-BF539/ADSP-BF539F processors contain a small boot kernel, which configures the appropriate peripheral for booting. If the processors are configured to boot from boot ROM memory space, they start executing from the on-chip boot ROM. For more information, see Booting Modes on Page 16.

Event Handling

The event controller handles all asynchronous and synchronous events to the processor. The processors provide event handling that supports both nesting and prioritization. Nesting allows multiple event service routines to be active simultaneously. Pri­oritization ensures that servicing of a higher priority event takes precedence over servicing of a lower priority event. The control­ler provides support for five different types of events:
• Emulation – An emulation event causes the processor to enter emulation mode, allowing command and control of the processor via the JTAG interface.
• Reset – This event resets the processor.
Rev. E | Page 6 of 60 | January 2011
ADSP-BF539/ADSP-BF539F
• Nonmaskable Interrupt (NMI) – The NMI event can be generated by the software watchdog timer or by the NMI input signal to the processor. The NMI event is frequently used as a power-down indicator to initiate an orderly shut­down of the system.
• Exceptions – Events that occur synchronously to program flow (i.e., the exception will be taken before the instruction is allowed to complete). Conditions such as data alignment violations and undefined instructions cause exceptions.
• Interrupts – Events that occur asynchronously to program flow. They are caused by input pins, timers, and other peripherals, as well as by an explicit software instruction.
Each event type has an associated register to hold the return address and an associated return-from-event instruction. When an event is triggered, the state of the processor is saved on the supervisor stack.
The ADSP-BF539/ADSP-BF539F processor’s event controller consists of two stages, the core event controller (CEC) and the system interrupt controller (SIC). The core event controller works with the system interrupt controller to prioritize and con­trol all system events. Conceptually, interrupts from the peripherals enter into the SIC and are then routed directly into the general-purpose interrupts of the CEC.

Core Event Controller (CEC)

The CEC supports nine general-purpose interrupts (IVG15– 7), in addition to the dedicated interrupt and exception events. Of these general-purpose interrupts, the two lowest priority inter­rupts (IVG15–14) are recommended to be reserved for software interrupt handlers, leaving seven prioritized interrupt inputs to support the processor’s peripherals. Table 2 describes the inputs to the CEC, identifies their names in the event vector table (EVT), and lists their priorities.

System Interrupt Controller (SIC)

The system interrupt controller (SIC) provides the mapping and routing of events from the many peripheral interrupt sources to the prioritized general-purpose interrupt inputs of the CEC. Although the ADSP-BF539/ADSP-BF539F processors provide a default mapping, the user can alter the mappings and priorities of interrupt events by writing the appropriate values into the interrupt assignment registers (SIC_IARx). Table 3 describes the inputs into the SIC and the default mappings into the CEC.

Event Control

The ADSP-BF539/ADSP-BF539F processors provide the user with a very flexible mechanism to control the processing of events. In the CEC, three registers are used to coordinate and control events. Each register is 32 bits wide:
• CEC interrupt latch register (ILAT) – The ILAT register indicates when events have been latched. The appropriate bit is set when the processor has latched the event and is cleared when the event has been accepted into the system. This register is updated automatically by the controller, but it can also be written to clear (cancel) latched events. This
register may be read while in supervisor mode and may only be written while in supervisor mode when the corre­sponding IMASK bit is cleared.
• CEC interrupt mask register (IMASK) – The IMASK regis­ter controls the masking and unmasking of individual events. When a bit is set in the IMASK register, that event is unmasked and will be processed by the CEC when asserted. A cleared bit in the IMASK register masks the event, preventing the processor from servicing the event even though the event can be latched in the ILAT register. This register can be read or written while in supervisor mode. General-purpose interrupts can be globally enabled and disabled with the STI and CLI instructions, respectively.
• CEC interrupt pending register (IPEND) – The IPEND register keeps track of all nested events. A set bit in the IPEND register indicates whether the event is currently active or nested at some level. This register is updated auto­matically by the controller but can be read while in supervisor mode.
The SIC allows further control of event processing by providing three 32-bit interrupt control and status registers. Each register contains a bit corresponding to each of the peripheral interrupt events shown in Table 3 on Page 8.
• SIC interrupt mask registers (SIC_IMASKx) – These regis­ters control the masking and unmasking of each peripheral interrupt event. When a bit is set in these registers, that peripheral event is unmasked and will be processed by the system when asserted. A cleared bit in these registers masks the peripheral event, preventing the processor from servic­ing the event.
• SIC interrupt status registers (SIC_ISRx) – As multiple peripherals can be mapped to a single event, these registers allow the software to determine which peripheral event source triggered the interrupt. A set bit indicates that the peripheral is asserting the interrupt, and a cleared bit indi­cates that the peripheral is not asserting the event.
• SIC interrupt wake-up enable registers (SIC_IWRx) – By enabling the corresponding bit in these registers, a periph­eral can be configured to wake up the processor, should the core be idled or in sleep mode when the event is generated. (For more information, see Dynamic Power Management
on Page 13.)
Because multiple interrupt sources can map to a single general­purpose interrupt, multiple pulse assertions can occur simulta­neously, before or during interrupt processing for an interrupt event already detected on this interrupt input. The IPEND reg­ister contents are monitored by the SIC as the interrupt acknowledgement.
The appropriate ILAT register bit is set when an interrupt rising edge is detected (detection requires two core clock cycles). The bit is cleared when the respective IPEND register bit is set. The IPEND bit indicates that the event has entered into the proces­sor pipeline. At this point the CEC will recognize and queue the next rising edge event on the corresponding event input.

DMA CONTROLLERS

The processors have multiple, independent DMA controllers that support automated data transfers with minimal overhead for the processor core. DMA transfers can occur between the ADSP-BF539/ADSP-BF539F processor internal memories and any of its DMA capable peripherals. Additionally, DMA trans­fers can be accomplished between any of the DMA-capable peripherals and external devices connected to the external memory interfaces, including the SDRAM controller and the asynchronous memory controller. DMA capable peripherals include the SPORTs, SPI ports, UARTs, and PPI. Each individ­ual DMA capable peripheral has at least one dedicated DMA channel. In addition, the MXVR peripheral has its own dedi­cated DMA controller, which supports its own unique set of operating modes.

The DMA controllers support both 1-dimensional (1-D) and 2­dimensional (2-D) DMA transfers. DMA transfer initialization can be implemented from registers or from sets of parameters called descriptor blocks.
The 2-D DMA capability supports arbitrary row and column sizes up to 64K elements by 64K elements and arbitrary row and column step sizes up to ±32K elements. Furthermore, the col­umn step size can be less than the row step size, allowing implementation of interleaved data streams. This feature is especially useful in video applications where data can be deinterleaved on the fly.
Examples of DMA types supported by the processor’s DMA controller include:
• A single, linear buffer that stops upon completion
• A circular, auto-refreshing buffer that interrupts on each full or fractionally full buffer
• 1-D or 2-D DMA using a linked list of descriptors
•2-D DMA using an array of descriptors, specifying only the base DMA address within a common page
In addition to the dedicated peripheral DMA channels, there are four memory DMA channels provided for transfers between the various memories of the ADSP-BF539/ADSP-BF539F processor system. This enables transfers of blocks of data between any of the memories—including external SDRAM, ROM, SRAM, and flash memory—with minimal processor intervention. Memory DMA transfers can be controlled by a very flexible descriptor­based methodology or by a standard register-based autobuffer mechanism.

REAL-TIME CLOCK

The ADSP-BF539/ADSP-BF539F processor real-time clock (RTC) provides a robust set of digital watch features, including current time, stopwatch, and alarm. The RTC is clocked by a
32.768 kHz crystal external to the Blackfin processors. The RTC peripheral has dedicated power supply pins so that it can remain powered up and clocked even when the rest of the processor is in a low power state. The RTC provides several programmable interrupt options, including interrupt per second, minute, hour, or day clock ticks, interrupt on programmable stopwatch count­down, or interrupt at a programmed alarm time.
The 32.768 kHz input clock frequency is divided down to a 1 Hz signal by a prescaler. The counter function of the timer consists of four counters: a 60-second counter, a 60-minute counter, a 24-hour counter, and an 32,768-day counter.
When enabled, the alarm function generates an interrupt when the output of the timer matches the programmed value in the alarm control register. There are two alarms: the first alarm is for a time of day. The second alarm is for a day and time of that day.
The stopwatch function counts down from a programmed value, with one second resolution. When the stopwatch is enabled and the counter underflows, an interrupt is generated.
Like the other peripherals, the RTC can wake up the processor from sleep mode upon generation of any RTC wake-up event. Additionally, an RTC wake-up event can wake up the processor from deep sleep mode, and wake up the on-chip internal voltage regulator from a powered down state.
Connect RTC pins RTXI and RTXO with external components as shown in Figure 5.
Figure 5. External Components for RTC

WATCHDOG TIMER

The processors include a 32-bit timer that can be used to imple­ment a software watchdog function. A software watchdog can improve system availability by forcing the processor to a known state through generation of a hardware reset, nonmaskable interrupt (NMI), or general-purpose interrupt, if the timer expires before being reset by software. Programs initialize the count value of the timer, enable the appropriate interrupt, and then enable the timer. Thereafter, the software must reload the counter before it counts to zero from the programmed value. This protects the system from remaining in an unknown state where software, which would normally reset the timer, has stopped running due to an external noise condition or software error.
If configured to generate a hardware reset, the watchdog timer resets both the core and the processor peripherals. After a reset, software can determine if the watchdog was the source of the hardware reset by interrogating a status bit in the watchdog timer control register.
The timer is clocked by the system clock (SCLK), at a maximum frequency of f
SCLK
.

TIMERS

There are four general-purpose programmable timer units in the ADSP-BF539/ADSP-BF539F processors. Three timers have an external pin that can be configured either as a pulse-width modulator (PWM) or timer output, as an input to clock the timer, or as a mechanism for measuring pulse widths and periods of external events. These timers can be synchronized to

an external clock input to the PF1 pin (TACLK), an external clock input to the PPI_CLK pin (TMRCLK), or to the internal SCLK.
The timer units can be used in conjunction with UART0 to measure the width of the pulses in the data stream to provide an auto-baud detect function for a serial channel.
The timers can generate interrupts to the processor core provid­ing periodic events for synchronization, either to the system clock or to a count of external signals.
In addition to the three general-purpose programmable timers, a fourth timer is also provided. This extra timer is clocked by the internal processor clock and is typically used as a system tick clock for generation of operating system periodic interrupts.

SERIAL PORTS (SPORTS)

The ADSP-BF539/ADSP-BF539F processors incorporate four dual-channel synchronous serial ports for serial and multipro­cessor communications. The SPORTs support the following features:
2
•I
S capable operation.
• Bidirectional operation – Each SPORT has two sets of inde­pendent transmit and receive pins, enabling 16 channels of
2
I
S stereo audio.
• Buffered (8-deep) transmit and receive ports – Each port has a data register for transferring data words to and from other processor components and shift registers for shifting data in and out of the data registers.
• Clocking – Each transmit and receive port can either use an external serial clock or generate its own, in frequencies ranging from (f
• Word length – Each SPORT supports serial data words from 3 bits to 32 bits in length, transferred most significant bit first or least significant bit first.
• Framing – Each transmit and receive port can run with or without frame sync signals for each data word. Frame sync signals can be generated internally or externally, active high or low, and with either of two pulse widths and early or late frame sync.
• Companding in hardware – Each SPORT can perform A-law or μ-law companding according to ITU recommen­dation G.711. Companding can be selected on the transmit and/or receive channel of the SPORT without additional latencies.
• DMA operatio ns with single-cycle overhead – Each SPORT can automatically receive and transmit multiple buffers of memory data. The processor can link or chain sequences of DMA transfers between a SPORT and memory.
• Interrupts – Each transmit and receive port generates an interrupt upon completing the transfer of a data word or after transferring an entire data buffer or buffers through DMA.
• Multichannel capability – Each SPORT supports 128 chan­nels out of a 1024-channel window and is compatible with the H.100, H.110, MVIP-90, and HMVIP standards.

SERIAL PERIPHERAL INTERFACE (SPI) PORTS

The processors incorporate three SPI-compatible ports that enable the processor to communicate with multiple SPI com­patible devices.
The SPI interface uses three pins for transferring data: two data pins (master output-slave input, MOSIx, and master input-slave output, MISOx) and a clock pin (serial clock, SCKx). An SPI chip select input pin (SPIxSS
) lets other SPI devices select the processor. For SPI0, seven SPI chip select output pins (SPI0SEL7–1
) let the processor select other SPI devices. SPI1 and SPI2 each have a single SPI chip select output pin (SPI1SEL1
and SPI2SEL1) for SPI point-to-point communica­tion. Each of the SPI select pins is a reconfigured GPIO pin. Using these pins, the SPI ports provide a full-duplex, synchro­nous serial interface, which supports both master/slave modes and multimaster environments.
The SPI ports’ baud rate and clock phase/polarities are pro­grammable, and they each have an integrated DMA controller, configurable to support transmit or receive data streams. Each SPI DMA controller can only service unidirectional accesses at any given time.
The SPI port clock rate is calculated as:
where the 16-bit SPIx_BAUD register contains a value of 2 to 65,535.
During transfers, the SPI port simultaneously transmits and receives by serially shifting data in and out on its two serial data lines. The serial clock line synchronizes the shifting and sam­pling of data on the two serial data lines.

2-WIRE INTERFACE

The processors incorporate two 2-wire interface (TWI) modules that are compatible with the Philips Inter-IC bus standard. The TWI modules offer the capabilities of simultaneous master and slave operation, support for 7-bit addressing, and multimedia data arbitration. The TWI also includes master clock synchroni­zation and support for clock low extension.
The TWI interface uses two pins for transferring clock (SCLx) and data (SDAx) and supports the protocol at speeds up to 400 kbps.
The TWI interface pins are compatible with 5 V logic levels.

UART PORTS

The processors incorporate three full-duplex universal asyn­chronous receiver/transmitter (UART) ports, which are fully compatible with PC standard UARTs. The UART ports provide a simplified UART interface to other peripherals or hosts, sup­porting full-duplex, DMA supported, asynchronous transfers of serial data. The UART ports include support for 5 data bits to 8 data bits, 1 stop bit or 2 stop bits, and none, even, or odd par­ity. The UART ports support two modes of operation:

• PIO (programmed I/O) – The processor sends or receives data by writing or reading I/O mapped UART registers. The data is double buffered on both transmit and receive.
• DMA (direct memory access) – The DMA controller trans­fers both transmit and receive data. This reduces the number and frequency of interrupts required to transfer data to and from memory. Each UART has two dedicated DMA channels, one for transmit and one for receive. These DMA channels have lower default priority than most DMA channels because of their relatively low service rates.
Each UART port’s baud rate, serial data format, error code gen­eration and status, and interrupts are programmable:

• Supporting data formats from 7 bits to 12 bits per frame.
• Both transmit and receive operations can be configured to generate maskable interrupts to the processor.
Each UART port’s clock rate is calculated as:
where the 16-bit UART_Divisor comes from the UARTx_DLH register (most significant 8 bits) and UARTx_DLL register (least significant 8 bits).
In conjunction with the general-purpose timer functions, auto­baud detection is supported on UART0.
The capabilities of the UARTs are further extended with sup­port for the Infrared Data Association (IrDA

PROGRAMMABLE I/O PINS

The ADSP-BF539/ADSP-BF539F processor has numerous peripherals that may not all be required for every application. Therefore, many of the pins have a secondary function as pro­grammable I/O pins. There are two types of programmable I/O pins with slightly different functionality: programmable flags and general-purpose I/O.

Programmable Flags (GPIO Port F)

There are 16 bidirectional, general-purpose programmable flag (PF15 – 0) pins on GPIO Port F. Each programmable flag can be individually controlled by manipulation of the flag control, sta­tus, and interrupt registers:
• Flag direction control register – Specifies the direction of each individual PFx pin as input or output.
• Flag control and status registers – The processors employ a “write one to modify” mechanism that allows any combi­nation of individual flags to be modified in a single instruction, without affecting the level of any other flags. Four control registers are provided. One register is written in order to set flag values, one register is written in order to clear flag values, one register is written in order to toggle flag values, and one register is written in order to specify a flag value. Reading the flag status register allows software to interrogate the sense of the flags.
• Flag interrupt mask registers – The two flag interrupt mask registers allow each individual PFx pin to function as an interrupt to the processor. Similar to the two flag control registers that are used to set and clear individual flag values, one flag interrupt mask register sets bits to enable interrupt function, and the other flag interrupt mask register clears bits to disable interrupt function. PFx pins defined as inputs can be configured to generate hardware interrupts, while output PFx pins can be triggered by software interrupts.
• Flag interrupt sensitivity registers – The two flag interrupt sensitivity registers specify whether individual PFx pins are level- or edge-sensitive and specify—if edge-sensitive— whether just the rising edge or both the rising and falling edges of the signal are significant. One register selects the type of sensitivity, and one register selects which edges are significant for edge-sensitivity.
The PFx pins can also be used by the SPI0 and PPI ports as shown in Table 4, depending on how the peripherals are config­ured. Care must be taken so that these pins are not used for multiple purposes simultaneously.

General-Purpose I/O Ports C, D, and E

There are 38 general-purpose I/O pins that are multiplexed with other peripherals. They are arranged into Ports C, D, and E as shown in Table 4. The GPIO differ from the programmable flags on Port F in that the GPIO pins cannot generate interrupts to the processor.

instruction, without affecting the level of any other GPIO pin. Four control registers and a data register are provided for each GPIO port. One register is written in order to set GPIO pin values, one register is written in order to clear GPIO pin values, one register is written in order to toggle GPIO pin values, and one register is written in order to specify a GPIO input or output. Reading the GPIO data register allows software to determine the state of the input GPIO pins.
Note that the GP pin is used to specify the status of the GPIO pins PC9–PC4 at power up. If GP is tied high, then pins PC9–PC4 are configured as GPIO after reset. The pins cannot be reconfigured through software, and special care must be taken with the MLF pin. If the GP pin is tied low, then the pins are configured as MXVR pins after reset but can be reconfig­ured as GPIO pins through software.

PARALLEL PERIPHERAL INTERFACE

The ADSP-BF539/ADSP-BF539F processors provide a parallel peripheral interface (PPI) that can connect directly to parallel ADC and DAC converters, video encoders and decoders, and other general-purpose peripherals. The PPI consists of a dedi­cated input clock pin, up to 3 frame synchronization pins, and up to 16 data pins. The input clock supports parallel data rates up to f figured as either inputs or outputs.
The PPI supports a variety of general-purpose and ITU-R 656 modes of operation. In general-purpose mode, the PPI provides half-duplex, bidirectional data transfer with up to 16 bits of data. Up to 3 frame synchronization signals are also provided. In ITU-R 656 mode, the PPI provides half-duplex, bidirectional transfer of 8- or 10-bit video data. Additionally, on-chip decode of embedded start-of-line (SOL) and start-of-field (SOF) pre­amble packets are supported.

General-Purpose Mode Descriptions

The general-purpose modes of the PPI are intended to suit a wide variety of data capture and transmission applications. Three distinct submodes are supported:

Input Mode

This mode is intended for ADC applications, as well as video communication with hardware signaling. In its simplest form, PPI_FS1 is an external frame sync input that controls when to read data. The PPI_DELAY MMR allows for a delay (in PPI_CLK cycles) between reception of this frame sync and the initiation of data reads. The number of input data samples is user programmable and defined by the contents of the PPI_COUNT register. The PPI supports 8-bit, and 10-bit through 16-bit data and are programmable in the PPI_CONTROL register.
/2 MHz, and the synchronization signals can be con-
SCLK
• Input Mode – Frame syncs and data are inputs into the PPI.
• Frame Capture Mode – Frame syncs are outputs from the PPI, but data are inputs.
• Output Mode – Frame syncs and data are outputs from the PPI.

Frame Capture Mode

This mode allows the video source(s) to act as a slave (e.g., for frame capture). The processors control when to read from the video source(s). PPI_FS1 is an HSYNC output, and PPI_FS2 is a VSYNC output.

Output Mode

This mode is used for transmitting video or other data with up to three output frame syncs. Typically, a single frame sync is appropriate for data converter applications, whereas two or three frame syncs could be used for sending video with hard­ware signaling.
ITU-R 656 Mode Descriptions
The ITU-R 656 modes of the PPI are intended to suit a wide variety of video capture, processing, and transmission applica­tions. Three distinct submodes are supported:
•Active Video Only Mode
• Vertical Blanking Only Mode
• Entire Field Mode

Active Video Only Mode

This mode is used when only the active video portion of a field is of interest and not any of the blanking intervals. The PPI will not read in any data between the end of active video (EAV) and start of active video (SAV) preamble symbols, or any data pres­ent during the vertical blanking intervals. In this mode, the control byte sequences are not stored to memory; they are filtered by the PPI. After synchronizing to the start of Field 1, the PPI ignores incoming samples until it sees an SAV code. The user specifies the number of active video lines per frame (in the PPI_COUNT register).

Vertical Blanking Interval Mode

In this mode, the PPI only transfers vertical blanking interval (VBI) data.

Entire Field Mode

In this mode, the entire incoming bit stream is read in through the PPI. This includes active video, control preamble sequences, and ancillary data that can be embedded in horizontal and verti­cal blanking intervals. Data transfer starts immediately after synchronization to Field 1.

CONTROLLER AREA NETWORK (CAN) INTERFACE

The ADSP-BF539/ADSP-BF539F processors provide a CAN controller that is a communication controller implementing the controller area network (CAN) V2.0B protocol. This protocol is an asynchronous communications protocol used in both indus­trial and automotive control systems. CAN is well suited for control applications due to its ability to communicate reliably over a network since the protocol incorporates CRC checking, message error tracking, and fault node confinement.
Rev. E | Page 12 of 60 | January 2011
ADSP-BF539/ADSP-BF539F
The CAN controller is based on a 32-entry mailbox RAM and supports both the standard and extended identifier (ID) mes­sage formats specified in the CAN protocol specification, Revision 2.0, Part B.
Each mailbox consists of eight 16-bit data words. The data is divided into fields, which includes a message identifier, a time stamp, a byte count, up to 8 bytes of data, and several control bits. Each node monitors the messages being passed on the net­work. If the identifier in the transmitted message matches an identifier in one of its mailboxes, then the module knows that the message was meant for it, passes the data into its appropriate mailbox, and signals the processor of message arrival with an interrupt.
The CAN controller can wake up the processor from sleep mode upon generation of a wake-up event, such that the processor can be maintained in a low power mode during idle conditions. Additionally, a CAN wake-up event can wake up the on-chip internal voltage regulator from the hibernate state.
The electrical characteristics of each network connection are very stringent; therefore, the CAN interface is typically divided into two parts: a controller and a transceiver. This allows a sin­gle controller to support different drivers and CAN networks. The ADSP-BF539/ADSP-BF539F CAN module represents the controller part of the interface. This module’s network I/O is a single transmit output and a single receive input, which connect to a line transceiver.
The CAN clock is derived from the processor system clock (SCLK) through a programmable divider and therefore does not require an additional crystal.

MEDIA TRANSCEIVER MAC LAYER (MXVR)

The ADSP-BF539/ADSP-BF539F processors provide a media transceiver (MXVR) MAC layer, allowing the processor to be connected directly to a MOST network through just an FOT or electrical PHY.
The MXVR is fully compatible with industry standard standalone MOST controller devices, supporting 22.579 Mbps or 24.576 Mbps data transfer. It offers faster lock times, greater jitter immunity, and a sophisticated DMA scheme for data transfers. The high speed internal interface to the core and L1 memory allows the full bandwidth of the network to be utilized. The MXVR can operate as either the network master or as a net­work slave.
Synchronous data is transferred to or from the synchronous data channels through eight programmable DMA engines. The synchronous data DMA engines can operate in various modes, including modes that trigger DMA operation when data pat­terns are detected in the receive data stream. Furthermore, two DMA engines support asynchronous traffic and control mes­sage traffic.
Interrupts are generated when a user-defined amount of syn­chronous data has been sent or received by the processor or when asynchronous packets or control messages have been sent or received.
The MXVR peripheral can wake up the processor from sleep mode when a wake-up preamble is received over the network or based on any other MXVR interrupt event. Additionally, detec­tion of network activity by the MXVR can be used to wake up the processor from sleep mode and wake up the on-chip inter­nal voltage regulator from the powered-down hibernate state. These features allow the processor to operate in a low-power state when there is no network activity or when data is not cur­rently being received or transmitted by the MXVR.
The MXVR clock is provided through a dedicated external crys­tal or crystal oscillator. For 44.1 kHz frame syncs, use a
45.1584 MHz crystal or oscillator; for 48 kHz frame syncs, use a
49.152 MHz crystal or oscillator. If using a crystal to provide the MXVR clock, use a parallel-resonant, fundamental mode, microprocessor-grade crystal.

DYNAMIC POWER MANAGEMENT

The ADSP-BF539/ADSP-BF539F processors provide four oper­ating modes, each with a different performance/power profile. In addition, dynamic power management provides the control functions to dynamically alter the processor core supply voltage, further reducing power dissipation. Control of clocking to each of the ADSP-BF539/ADSP-BF539F processor peripherals also reduces power consumption. See Table 5 for a summary of the power settings for each mode.

Full-On Operating Mode—Maximum Performance

In the full-on mode, the PLL is enabled and is not bypassed, providing capability for maximum operational frequency. This is the power-up default execution state in which maximum per­formance can be achieved. The processor core and all enabled peripherals run at full speed.

Active Operating Mode—Moderate Dynamic Power Savings

In the active mode, the PLL is enabled but bypassed. Because the PLL is bypassed, the processor’s core clock (CCLK) and system clock (SCLK) run at the input clock (CLKIN) frequency. DMA access is available to appropriately configured L1 memories.
In the active mode, it is possible to disable the PLL through the PLL Control register (PLL_CTL). If disabled, the PLL must be re-enabled before transitioning to the full-on or sleep modes.

Sleep Operating Mode—High Dynamic Power Savings

The sleep mode reduces dynamic power dissipation by disabling the clock to the processor core (CCLK). The PLL and system clock (SCLK), however, continue to operate in this mode. Typi­cally, an external event or RTC activity wakes up the processor. When in the sleep mode, assertion of a wake-up event enabled in the SIC_IWRx register causes the processor to sense the value of the BYPASS bit in the PLL control register (PLL_CTL). If BYPASS is disabled, the processor transitions to the full on mode. If BYPASS is enabled, the processor will transition to the active mode. When in the sleep mode, system DMA access to L1 memory is not supported.

Deep Sleep Operating Mode—Maximum Dynamic Power Savings

The deep sleep mode maximizes dynamic power savings by dis­abling the clocks to the processor core (CCLK) and to all synchronous peripherals (SCLK). Asynchronous peripherals such as the RTC may still be running but will not be able to access internal resources or external memory. This powered­down mode can only be exited by assertion of the reset interrupt (RESET
) or by an asynchronous interrupt generated by the RTC. When in deep sleep mode, an RTC asynchronous interrupt causes the processor to transition to the active mode. Assertion of RESET
while in deep sleep mode causes the proces-
sor to transition to the full-on mode.

Hibernate State—Maximum Static Power Savings

The hibernate state maximizes static power savings by disabling the voltage and clocks to the processor core (CCLK) and to all the synchronous peripherals (SCLK). The internal voltage regu­lator for the processor can be shut off by writing b#00 to the FREQ bits of the VR_CTL register. This sets the internal power supply voltage (V
) to 0 V to provide the lowest static power
DDINT
dissipation. Any critical information stored internally (memory contents, register contents, etc.) must be written to a nonvolatile storage device prior to removing power if the processor state is to be preserved. Since V
can still be supplied in this mode,
DDEXT
all of the external pins three-state, unless otherwise specified. This allows other devices that may be connected to the proces­sor to still have power applied without drawing unwanted current. The internal supply regulator can be woken up either by a real-time clock wake-up, by CAN bus traffic, by asserting the RESET
pin, or by an external source via the GPW pin.

Power Savings

As shown in Table 6, the ADSP-BF539/ADSP-BF539F proces­sors support five different power domains. The use of multiple power domains maximizes flexibility, while maintaining com­pliance with industry standards and conventions:
• The 3.3 V VDDRTC power domain supplies the RTC I/O and logic so that the RTC can remain functional when the rest of the chip is powered off.
• The 3.3 V MXEVDD power domain supplies the MXVR crystal and is separate to provide noise isolation.
• The 1.25 V MPIVDD power domain supplies the MXVR PLL and is separate to provide noise isolation.
• The 1.25 V VDDINT power domain supplies all internal logic except for the RTC logic and the MXVR PLL.
• The 3.3 V VDDEXT power domain supplies all I/O except for the RTC and MXVR crystals.
There are no sequencing requirements for the various power domains.

The power dissipated by a processor is largely a function of the clock frequency of the processor and the square of the operating voltage. For example, reducing the clock frequency by 25% results in a 25% reduction in dynamic power dissipation, while reducing the voltage by 25% reduces dynamic power dissipation by more than 40%. Further, these power savings are additive in that, if the clock frequency and supply voltage are both reduced, the power savings can be dramatic.
The dynamic power management feature of the ADSP-BF539/ADSP-BF539F processors allow both the proces­sor input voltage (V
) and clock frequency (f

dynamically controlled.
The savings in power dissipation can be modeled using the power savings factor and % power savings calculations.

VOLTAGE REGULATION

The Blackfin processors provide an on-chip voltage regulator that can generate appropriate V V
supply. See Operating Conditions on Page 26 for regula-
DDEXT
tor tolerances and acceptable V
The regulator controls the internal logic voltage levels and is programmable with the voltage regulator control register (VR_CTL) in increments of 50 mV. To reduce standby power consumption, the internal voltage regulator can be programmed to remove power to the processor core while I/O power (VDDRTC, MXEVDD, VDDEXT) is still supplied. While in the hibernate state, I/O power is still being applied, eliminating the need for external buffers. The voltage regulator can be activated from this power-down state through an RTC wake-up, a CAN wake-up, an MXVR wake-up, a general-purpose wake-up, or by asserting RESET
, all of which will then initiate a boot sequence. The regulator can also be disabled and bypassed at the user’s discretion.

If an external clock is used, it should be a TTL-compatible signal and must not be halted, changed, or operated below the speci­fied frequency during normal operation. This signal is connected to the processor’s CLKIN pin. When an external clock is used, the XTAL pin must be left unconnected.
Alternatively, because the processors include an on-chip oscilla­tor circuit, an external crystal can be used. For fundamental frequency operation, use the circuit shown in Figure 7. A paral­lel-resonant, fundamental frequency, microprocessor-grade crystal is connected across the CLKIN and XTAL pins. The on­chip resistance between CLKIN and the XTAL pin is in the 500 kW range. Further parallel resistors are typically not recom­mended. The two capacitors and the series resistor, shown in
Figure 7, fine tune the phase and amplitude of the sine fre-
quency. The capacitor and resistor values, shown in Figure 7, are typical values only. The capacitor values are dependent upon the crystal manufacturer’s load capacitance recommendations and the physical PCB layout. The resistor value depends on the drive level specified by the crystal manufacturer. System designs should verify the customized values based on careful investiga­tion on multiple devices over the allowed temperature range.
A third-overtone crystal can be used at frequencies above 25 MHz. The circuit is then modified to ensure crystal operation only at the third overtone, by adding a tuned inductor circuit as shown in Figure 7.
As shown in Figure 8 on Page 16, the core clock (CCLK) and system peripheral clock (SCLK) are derived from the input clock (CLKIN) signal. An on-chip PLL is capable of multiplying the CLKIN signal by a user programmable 0.5× to 64× multipli­cation factor (bounded by specified minimum and maximum VCO frequencies). The default multiplier is 10×, but it can be modified by a software instruction sequence. On-the-fly fre­quency changes can be effected by simply writing to the PLL_DIV register.

CLOCK SIGNALS

The ADSP-BF539/ADSP-BF539F processors can be clocked by

an external crystal, a sine wave input, or a buffered, shaped clock derived from an external clock oscillator.

All on-chip peripherals are clocked by the system clock (SCLK). The system clock frequency is programmable by means of the SSEL3–0 bits of the PLL_DIV register. The values programmed into the SSEL fields define a divide ratio between the PLL output (VCO) and the system clock. SCLK divider values are 1 through
15. Table 7 illustrates typical system clock ratios.

Signal Name SSEL3–0

The maximum frequency of the system clock is f the divisor ratio must be chosen to limit the system clock fre­quency to its maximum of f dynamically without any PLL lock latencies by writing the appropriate values to the PLL divisor register (PLL_DIV).
Note that when the SSEL value is changed, it will affect all the peripherals that derive their clock signals from the SCLK signal.
The core clock (CCLK) frequency can also be dynamically changed by means of the CSEL1–0 bits of the PLL_DIV register. Supported CCLK divider ratios are 1, 2, 4, and 8, as shown in
Table 8. This programmable core clock capability is useful for
fast core frequency modifications.

BOOTING MODES

The ADSP-BF539/ADSP-BF539F processors have three mecha­nisms (listed in Table 9) for automatically loading internal L1 instruction memory after a reset. A fourth mode is provided to execute from external memory, bypassing the boot sequence.
Table 9. Booting Modes
BMODE1–0 Description
00 Execute from 16-bit external memory
01 Boot from 8-bit or 16-bit flash or boot from on-chip
10 Boot from SPI serial master connected to SPI0
11 Boot from SPI serial slave EEPROM/flash
The BMODE pins of the reset configuration register, sampled during power-on resets and software initiated resets, implement the following modes:
• Execute from 16-bit external memory – Execution starts from address 0x2000 0000 with 16-bit packing. The boot ROM is bypassed in this mode. All configuration settings are set for the slowest device possible (3-cycle hold time; 15-cycle R/W access times; 4-cycle setup).
• Boot from 8-bit or 16-bit external flash memory – The 8-bit flash boot routine located in boot ROM memory space is
. Note that
SCLK

set up using asynchronous memory bank 0. For ADSP-BF539F processors, if FCE then the on-chip flash is booted. All configuration settings are set for the slowest device possible (3-cycle hold time; 15-cycle R/W access times; 4-cycle setup).
• Boot from SPI serial EEPROM/flash (8-, 16-, or 24-bit addressable, or Atmel AT45DB041, AT45DB081, or AT45DB161) connected to SPI0 – The SPI0 port uses the PF2 output pin to select a single SPI EEPROM/flash device, submits a read command and successive address bytes (0x00) until a valid 8-, 16-, or 24-bit, or Atmel addressable device is detected, and begins clocking data into the begin­ning of the L1 instruction memory.
• Boot from SPI host device connected to SPI0 – The Black­fin processor operates in SPI slave mode and is configured to receive the bytes of the .LDR file from an SPI host (mas­ter) agent. To hold off the host device from transmitting while the boot ROM is busy, the Blackfin processor asserts a GPIO pin, called host wait (HWAIT), to signal the host device not to send any more bytes until the flag is deas­serted. The flag is chosen by the user and this information is transferred to the Blackfin processor via bits 10:5 of the FLAG header in the .LDR image.
For each of the boot modes, a 10-byte header is first read from an external memory device. The header specifies the number of bytes to be transferred and the memory destination address.

Multiple memory blocks can be loaded by any boot sequence. Once all blocks are loaded, program execution commences from the start of L1 instruction SRAM.
In addition, Bit 4 of the reset configuration register can be set by application code to bypass the normal boot sequence during a software reset. For this case, the processor jumps directly to the beginning of L1 instruction memory.
To augment the boot modes, a secondary software loader is pro­vided that adds additional booting mechanisms. This secondary loader provides the ability to boot from 16-bit flash memory, fast flash, variable baud rate, and other sources. In all boot modes except bypass, program execution starts from on-chip L1 memory address 0xFFA0 0000.

INSTRUCTION SET DESCRIPTION

The Blackfin processor family assembly language instruction set employs an algebraic syntax designed for ease of coding and readability. The instructions have been specifically tuned to pro­vide a flexible, densely encoded instruction set that compiles to a very small final memory size. The instruction set also provides fully featured multifunction instructions that allow the pro­grammer to use many of the processor core resources in a single instruction. Coupled with many features more often seen on microcontrollers, this instruction set is very efficient when com­piling C and C++ source code. In addition, the architecture supports both user (algorithm/application code) and supervisor (O/S kernel, device drivers, debuggers, ISRs) modes of opera­tion, allowing multiple levels of access to core processor resources.
The assembly language, which takes advantage of the proces­sor’s unique architecture, offers the following advantages:
• Seamlessly integrated DSP/CPU features are optimized for both 8-bit and 16-bit operations.
• A multi-issue load/store modified Harvard architecture, which supports two 16-bit MAC or four 8-bit ALU plus two load/store plus two pointer updates per cycle.
• All registers, I/O, and memory are mapped into a unified 4G byte memory space, providing a simplified program­ming model.
• Microcontroller features, such as arbitrary bit and bit-field manipulation, insertion, and extraction; integer operations on 8-, 16-, and 32-bit data types; and separate user and supervisor stack pointers.
• Code density enhancements, which include intermixing of 16-bit and 32-bit instructions (no mode switching, no code segregation). Frequently used instructions are encoded in 16 bits.

DEVELOPMENT TOOLS

The ADSP-BF539/ADSP-BF539F processors are supported by a complete set of CROSSCORE ment tools, including Analog Devices emulators and VisualDSP++ development environment. The same emulator hardware that supports other Blackfin processors also fully emulates the ADSP-BF539/ADSP-BF539F processor.
®
software and hardware develop-
The VisualDSP++ project management environment lets pro­grammers develop and debug an application. This environment includes an easy to use assembler (which is based on an alge­braic syntax), an archiver (librarian/library builder), a linker, a loader, a cycle-accurate instruction-level simulator, a C/C++ compiler, and a C/C++ runtime library that includes DSP and mathematical functions. A key point for these tools is C/C++ code efficiency. The compiler has been developed for efficient translation of C/C++ code to processor assembly. The processor has architectural features that improve the efficiency of com­piled C/C++ code.
The VisualDSP++ debugger has a number of important fea­tures. Data visualization is enhanced by a plotting package that offers a significant level of flexibility. This graphical representa­tion of user data enables the programmer to quickly determine the performance of an algorithm. As algorithms grow in com­plexity, this capability can have increasing significance on the designer’s development schedule, increasing productivity. Sta­tistical profiling enables the programmer to nonintrusively poll the processor as it is running the program. This feature, unique to VisualDSP++, enables the software developer to passively gather important code execution metrics without interrupting the real-time characteristics of the program. Essentially, the developer can identify bottlenecks in software quickly and efficiently. By using the profiler, the programmer can focus on those areas in the program that impact performance and take corrective action.
Debugging both C/C++ and assembly programs with the VisualDSP++ debugger, programmers can
• View mixed C/C++ and assembly code (interleaved source and object information).
• Insert breakpoints.
• Set conditional breakpoints on registers, memory, and stacks.
• Trace instruction execution.
• Perform linear or statistical profiling of program execution.
• Fill, dump, and graphically plot the contents of memory.
• Perform source level debugging.
• Create custom debugger windows.
The VisualDSP++ IDDE lets programmers define and manage software development. Its dialog boxes and property pages let programmers configure and manage all of the Blackfin develop­ment tools, including the color syntax highlighting in the VisualDSP++ editor. This capability permits programmers to
• Control how the development tools process inputs and generate outputs.
• Maintain a one-to-one correspondence with the tool’s command line switches.
The VisualDSP++ Kernel (VDK) incorporates scheduling and resource management tailored specifically to address the mem­ory and timing constraints of DSP programming. These capabilities enable engineers to develop code more effectively, eliminating the need to start from the very beginning, when
Rev. E | Page 17 of 60 | January 2011
ADSP-BF539/ADSP-BF539F
developing new application code. The VDK features include threads, critical and unscheduled regions, semaphores, events, and device flags. The VDK also supports priority-based, pre­emptive, cooperative, and time-sliced scheduling approaches. In addition, the VDK was designed to be scalable. If the application does not use a specific feature, the support code for that feature is excluded from the target system.
Because the VDK is a library, a developer can decide whether to use it or not. The VDK is integrated into the VisualDSP++ development environment, but can also be used via standard command line tools. When the VDK is used, the development environment assists the developer with many error prone tasks and assists in managing system resources, automating the gen­eration of various VDK-based objects, and visualizing the system state, when debugging an application that uses the VDK.
Use the Expert Linker to visually manipulate the placement of code and data on the embedded system. View memory utiliza­tion in a color-coded graphical form, easily move code and data to different areas of the processor or external memory with the drag of the mouse and examine run-time stack and heap usage. The Expert Linker is fully compatible with existing Linker Defi­nition File (LDF), allowing the developer to move between the graphical and textual environments.
Analog Devices emulators use the IEEE 1149.1 JTAG Test Access Port of the ADSP-BF539/ADSP-BF539F processors to monitor and control the target board processor during emula­tion. The emulator provides full-speed emulation, allowing inspection and modification of memory, registers, and proces­sor stacks. Nonintrusive in-circuit emulation is assured by the use of the processor’s JTAG interface—the emulator does not affect target system loading or timing.
In addition to the software and hardware development tools available from Analog Devices third parties provide a wide range of tools supporting the Blackfin processor family. Hard­ware tools include Blackfin processor PC plug-in cards. Third party software tools include DSP libraries, real-time operating systems, and block diagram design tools.

DESIGNING AN EMULATOR COMPATIBLE PROCESSOR BOARD

The Analog Devices family of emulators are tools that every sys­tem developer needs to test and debug hardware and software systems. Analog Devices has supplied an IEEE 1149.1 JTAG Test Access Port (TAP) on each JTAG processor. The emulator uses the TAP to access the internal features of the processor, allowing the developer to load code, set breakpoints, observe variables, observe memory, and examine registers. The proces­sor must be halted to send data and commands, but once an operation has been completed by the emulator, the processor system is set running at full speed with no impact on system timing.
To use these emulators, the target board must include a header that connects the processor’s JTAG port to the emulator.
For details on target board design issues including mechanical layout, single processor connections, multiprocessor scan chains, signal buffering, signal termination, and emulator pod
logic, see Analog Devices JTAG Emulation Technical Reference (EE-68) on the Analog Devices web site (www.analog.com)— use site search on “EE-68.” This document is updated regularly to keep pace with improvements to emulator support.

• The traces between the ADSP-BF539/ADSP-BF539F pro­cessor and the FOT should be kept as short as possible.
• The receive data trace connecting the FOT receive data output pin to the ADSP-BF539/ADSP-BF539F MRX input pin should not have a series termination resistor. The edge rate of the FOT receive data signal driven by the FOT is typically very slow, and further degradation of the edge rate is not desirable.
• The transmit data trace connecting the processor’s MTX output pin to the FOT Transmit Data input pin should have a 27 W series termination resistor placed close to the ADSP-BF539/ADSP-BF539F MTX pin.
• The receive data trace and the transmit data trace between the processor and the FOT should not be routed close to each other in parallel over long distances to avoid crosstalk.

VOLTAGE REGULATOR LAYOUT GUIDELINES

Regulator external component placement, board routing, and bypass capacitors all have a significant effect on noise injected into the other analog circuits on-chip. The VROUT1-0 traces and voltage regulator external components should be consid­ered as noise sources when doing board layout and should not be routed or placed near sensitive circuits or components on the board. All internal and I/O power supplies should be well bypassed with bypass capacitors placed as close to the ADSP-BF539/ADSP-BF539F as possible.

A signal chain is a series of signal-conditioning electronic com­ponents that receive input (data acquired from sampling either real-time phenomena or from stored data) in tandem, with the output of one portion of the chain supplying input to the next. Signal chains are often used in signal processing applications to gather and process data or to apply system controls based on analysis of real-time phenomena.

PIN DESCRIPTIONS

ADSP-BF539/ADSP-BF539F
ADSP-BF539/ADSP-BF539F processor pin definitions are listed in Table 10.
All pins are three-stated during and immediately after reset, except the memory interface, asynchronous memory control, and synchronous memory control pins. These pins are all driven high, with the exception of CLKOUT, which toggles at the system clock rate. If BR
is active (whether or not RESET is
asserted), the memory pins are also three-stated. All unused I/O
pins that need pull-ups or pull-downs, as noted in the table. During hibernate, all outputs are three-stated unless otherwise noted in Table 10.
In order to maintain maximum functionality and reduce pack­age size and pin count, some pins have dual, multiplexed functionality. In cases where pin functionality is reconfigurable, the default state is shown in plain text, while alternate function­ality is shown in italics.

System designers should refer to Estimating Power for the ADSP-BF538/BF539 Blackfin Processors (EE-298), which pro-
vides detailed information for optimizing designs for lowest power. All topics discussed in this section are described in detail in EE-298. Total power dissipation has two components:
1. Static, including leakage current
2. Dynamic, due to transistor switching characteristics
Many operating conditions can also affect power dissipation, including temperature, voltage, operating frequency, and pro-
current dissipation for internal circuitry (V fies static power dissipation as a function of voltage (V temperature (see Table 14), and I

TEST CONDITIONS

All timing parameters appearing in this data sheet were mea­sured under the conditions described in this section. Figure 43 shows the measurement point for ac measurements (except out­put enable/disable). The measurement point V V
(nominal) = 3.3 V.

Measurements (Except Output Enable/Disable)

Output Enable Time Measurement

Output pins are considered to be enabled when they have made a transition from a high impedance state to the point when they start driving.
The output enable time t
is the interval from the point when
ENA
a reference signal reaches a high or low voltage level to the point when the output starts driving as shown on the right side of
Figure 44 on Page 52.
The time t

If multiple pins (such as the data bus) are enabled, the measure­ment value is that of the first pin to start driving.

Output Disable Time Measurement

Output pins are considered to be disabled when they stop driv­ing, go into a high impedance state, and start to decay from their output high or low voltage. The output disable time t difference between t

Example System Hold Time Calculation

To determine the data output hold time in a particular system, first calculate t

times as specified in the Timing Specifications on Page 31 (for example, t
for an SDRAM write cycle as shown in Table 26

on Page 36).

Capacitive Loading

Output delays and holds are based on standard capacitive loads: 30 pF on all pins (see Figure 45). V

DDEXT
(nominal) = 3.3 V. Figure 46 on Page 53 through Figure 55 on
Page 54 show how output rise and fall times vary with capaci-
tance. The delay and hold specifications given should be de­rated by a factor derived from these figures. The graphs in these figures may not be linear outside the ranges shown.
The time for the voltage on the bus to decay by ΔV is dependent on the capacitive load C
and the load current IL. This decay
L
time can be approximated by the equation:
The time t ΔV equal to 0.5 V for V
