1.2 Description

The TMS320DM6441 (also referenced as DM6441) leverages TI’s DaVinci™ technology to meet the networked media encode and decode application processing needs of next-generation embedded devices.
The DM6441 enables OEMs and ODMs to quickly bring to market devices featuring robust operating systems support, rich user interfaces, high processing performance, and long battery life through the maximum flexibility of a fully integrated mixed processor solution.
The dual-core architecture of the DM6441 provides benefits of both DSP and Reduced Instruction Set Computer (RISC) technologies, incorporating a high-performance TMS320C64x+ DSP core and an ARM926EJ-S core.
The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and processes 32-bit, 16-bit, or 8-bit data. The core uses pipelining so that all parts of the processor and memory system can operate continuously.
The ARM core incorporates:
A coprocessor 15 (CP15) and protection module
Data and program memory management units (MMUs) with table look-aside buffers.
Separate 16K-byte instruction and 8K-byte data caches. Both are four-way associative with virtual index virtual tag (VIVT).
The TMS320C64x+™ DSPs are the highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. It is based on an enhanced version of the second-generation high-performance, advanced very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making these DSP cores an excellent choice for digital media applications. The C64x is a code-compatible member of the C6000™ DSP platform. The TMS320C64x+ DSP is an enhancement of the C64x+ DSP with added functionality and an expanded instruction set.
SPRS359E–SEPTEMBER 2006–REVISED AUGUST 2010
Any reference to the C64x DSP or C64x CPU also applies, unless otherwise noted, to the C64x+ DSP and C64x+ CPU, respectively.
With performance of up to 4104 million instructions per second (MIPS) at a clock rate of 513 MHz, the C64x+ core offers solutions to high-performance DSP programming challenges. The DSP core possesses the operational flexibility of high-speed controllers and the numerical capability of array processors. The C64x+ DSP core processor has 64 general-purpose registers of 32-bit word length and eight highly independent functional units—two multipliers for a 32-bit result and six arithmetic logic units (ALUs). The eight functional units include instructions to accelerate the performance in video and imaging applications. The DSP core can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of 2052 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 4104 MMACS. For more details on the C64x+ DSP, see the TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide (literature number SPRU732).
The DM6441 also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals similar to the other C6000 DSP platform devices. The DM6441 core uses a two-level cache-based architecture. The Level 1 program cache (L1P) is a 256K-bit direct mapped cache and the Level 1 data cache (L1D) is a 640K-bit 2-way set-associative cache. The Level 2 memory/cache (L2) consists of an 512K-bit memory space that is shared between program and data space. L2 memory can be configured as mapped memory, cache, or combinations of the two.
The peripheral set includes: two configurable video ports; a 10/100 Mb/s Ethernet MAC (EMAC) with a management data input/output (MDIO) module; an inter-integrated circuit (I2C) bus interface; one audio serial port (ASP); two 64-bit general-purpose timers each configurable as two independent 32-bit timers; one 64-bit watchdog timer; up to 71 pins of general-purpose input/output (GPIO) with programmable interrupt/event generation modes, multiplexed with other peripherals; three UARTs with hardware handshaking support on one UART; three pulse width modulator (PWM) peripherals; and two external memory interfaces: an asynchronous external memory interface (EMIFA) for slower memories/peripherals, and a higher speed synchronous memory interface for DDR2.

SPRS359E–SEPTEMBER 2006–REVISED AUGUST 2010
The DM6441 device includes a video processing subsystem (VPSS) with two configurable video/imaging peripherals: one video processing front-end (VPFE) input used for video capture, one video processing back-end (VPBE) output with imaging coprocessor (VICP) used for display.
The video processing front-end (VPFE) consists of a CCD controller (CCDC), a preview engine (previewer), histogram module, auto-exposure/white balance/focus module (H3A), and resizer. The CCDC is capable of interfacing to common video decoders, CMOS sensors, and charge coupled devices (CCDs). The previewer is a real-time image processing engine that takes raw imager data from a CMOS sensor or CCD and converts from an RGB Bayer pattern to YUV4:2:2. The histogram and H3A modules provide statistical information on the raw color data for use by the DM6441. The resizer accepts image data for separate horizontal and vertical resizing from 1/4x to 4x in increments of 256/N, where N is between 64 and 1024.
The video processing back-end (VPBE) consists of an on-screen display engine (OSD) and a video encoder (VENC). The OSD engine is capable of handling two separate video windows and two separate OSD windows. Other configurations include two video windows, one OSD window, and one attribute window allowing up to eight levels of alpha blending. The VENC provides four analog DACs that run at 54 MHz, providing a means for composite NTSC/PAL video, S-Video, and/or component video output. The VENC also provides up to 24 bits of digital output to interface to RGB888 devices. The digital output is capable of 8/16-bit BT.656 output and/or CCIR.601 with separate horizontal and vertical syncs. VFocus (part of the VPBE functionality and operationally (e.g., 16-bit multiplexed address/data) is also provided.
The Ethernet media access controller (EMAC) provides an efficient interface between the DM6441 and the network. The DM6441 EMAC support both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex mode, with hardware flow control and quality of service (QOS) support.
www.ti.com
The management data input/output (MDIO) module continuously polls all 32 MDIO addresses in order to enumerate all PHY devices in the system. Once a PHY candidate has been selected by the ARM, the MDIO module transparently monitors its link state by reading the PHY status register. Link change events are stored in the MDIO module and can optionally interrupt the ARM, allowing the ARM to poll the link status of the device without continuously performing costly MDIO accesses.
The HPI, I2C, SPI, USB2.0, and VLYNQ ports allow DM6441 to easily control peripheral devices and/or communicate with host processors. The DM6441 also provides Memory Stick/Memory Stick PRO card support, MMC/SD with SDIO support, and a universal serial bus (USB).
The DM6441 also includes a video/imaging coprocessor (VICP) to offload many video and imaging processing tasks from the DSP core, making more DSP MIPS available for common video and imaging algorithms. For more information on the VICP enhanced codecs, such as H.264 and MPEG4, please contact your nearest TI sales representative.
The rich peripheral set provides the ability to control external peripheral devices and communicate with external processors. For details on each of the peripherals, see the related sections later in this document and the associated peripheral reference guides listed in Section 2.8.3.1, Related Documentation From Texas Instruments.
The DM6441 has a complete set of development tools for both the ARM and DSP. These include C compilers, a DSP assembly optimizer to simplify programming and scheduling, and a Windows™ debugger interface for visibility into source code execution.

2.3.1 ARM926EJ-S RISC CPU

The ARM subsystem integrates the ARM926EJ-S processor. The ARM926EJ-S processor is a member of ARM9 family of general-purpose microprocessors. This processor is targeted at multi-tasking applications where full memory management, high performance, low die size, and low power are all important. The ARM926EJ-S processor supports the 32-bit ARM and 16-bit THUMB instruction sets, enabling the user to trade off between high performance and high code density. Specifically, the ARM926EJ-S processor supports the ARMv5TEJ instruction set, which includes features for efficient execution of Java byte codes, providing Java performance similar to Just in Time (JIT) Java interpreter, but without associated code overhead.
The ARM926EJ-S processor supports the ARM debug architecture and includes logic to assist in both hardware and software debug. The ARM926EJ-S processor has a Harvard architecture and provides a complete high performance subsystem, including:
ARM926EJ -S integer core
CP15 system control coprocessor
Memory management unit (MMU)
Separate instruction and data caches
Write buffer
Separate instruction and data tightly-coupled memories (TCMs) [internal RAM] interfaces
Separate instruction and data AHB bus interfaces
Embedded trace module and embedded trace buffer (ETM/ETB)
www.ti.com
For more complete details on the ARM9, refer to the ARM926EJ-S Technical Reference Manual, available at http://www.arm.com.

2.3.2 CP15

The ARM926EJ-S system control coprocessor (CP15) is used to configure and control instruction and data caches, tightly-coupled memories (TCMs), memory management unit (MMU), and other ARM subsystem functions. The CP15 registers are programmed using the MRC and MCR ARM instructions, when the ARM in a privileged mode such as supervisor or system mode.

2.3.3 MMU

The ARM926EJ-S MMU provides virtual memory features required by operating systems such as Linux™, WindowCE®, Ultron®, ThreadX®, etc. A single set of two level page tables stored in main memory is used to control the address translation, permission checks and memory region attributes for both data and instruction accesses. The MMU uses a single unified translation lookaside buffer (TLB) to cache the information held in the page tables. The MMU features are:
Standard ARM architecture v4 and v5 MMU mapping sizes, domains and access protection scheme.
Mapping sizes are: – 1MB (sections) – 64KB (large pages) – 4KB (small pages) – 1KB (tiny pages)
Access permissions for large pages and small pages can be specified separately for each quarter of the page (subpage permissions)
Hardware page table walks
Invalidate entire TLB, using CP15 register 8
Invalidate TLB entry, selected by MVA, using CP15 register 8
Lockdown of TLB entries, using CP15 register 10

2.3.4 Caches and Write Buffer

The size of the instruction cache is 16KB, data cache is 8KB. Additionally, the caches have the following features:
Virtual index, virtual tag, and addressed using the modified virtual address (MVA)
Four-way set associative, with a cache line length of eight words per line (32-bytes per line) and with two dirty bits in the Dcache
Dcache supports write-through and write-back (or copy back) cache operation, selected by memory region using the C and B bits in the MMU translation tables.
Critical-word first cache refilling
Cache lockdown registers enable control over which cache ways are used for allocation on a line fill, providing a mechanism for both lockdown, and controlling cache corruption
Dcache stores the physical address TAG (PA TAG) corresponding to each Dcache entry in the TAG RAM for use during the cache line write-backs, in addition to the virtual address TAG stored in the TAG RAM. This means that the MMU is not involved in Dcache write-back operations, removing the possibility of TLB misses related to the write-back address.
Cache maintenance operations provide efficient invalidation of, the entire Dcache or Icache, regions of the Dcache or Icache, and regions of virtual memory.
The write buffer is used for all writes to a noncachable bufferable region, write-through region and write misses to a write-back region. A separate buffer is incorporated in the Dcache for holding write-back for cache line evictions or cleaning of dirty cache lines. The main write buffer has 16-word data buffer and a four-address buffer. The Dcache write-back has eight data word entries and a single address entry.
SPRS359E–SEPTEMBER 2006–REVISED AUGUST 2010

2.3.5 Tightly Coupled Memory (TCM)

ARM internal RAM is provided for storing real-time and performance-critical code/data and the interrupt vector table. ARM internal ROM enables non-EMIFA boot options, such as NAND and UART. The RAM and ROM memories interfaced to the ARM926EJ-S via the tightly coupled memory interface that provides for separate instruction and data bus connections. Since the ARM TCM does not allow instructions on the D-TCM bus or data on the I-TCM bus, an arbiter is included so that both data and instructions can be stored in the internal RAM/ROM. The arbiter also allows accesses to the RAM/ROM from extra-ARM sources (e.g., EDMA3 or other masters). The ARM926EJ-S has built-in DMA support for direct accesses to the ARM internal memory from a non-ARM master. Because of the time-critical nature of the TCM link to the ARM internal memory, all accesses from non-ARM devices are treated as DMA transfers.
Instruction and data accesses are differentiated via accessing different memory map regions, with the instruction region from 0x0000 through 0x7FFF and data from 0x8000 through 0xFFFF. The instruction region at 0x0000 and data region at 0x8000 map to the same physical 16K-byte TCM RAM. Placing the instruction region at 0x0000 is necessary to allow the ARM interrupt vector table to be placed at 0x0000, as required by the ARM architecture. The internal 16K-byte RAM is split into two physical banks of 8KB each, which allows simultaneous instruction and data accesses to be accomplished if the code and data are in separate banks.

2.3.6 Advanced High-performance Bus (AHB)

The ARM subsystem uses the AHB port of the ARM926EJ-S to connect the ARM to the config bus and the external memories. Arbiters are employed to arbitrate access to the separate D-AHB and I-AHB by the config bus and the external memories bus.

2.3.7 Embedded Trace Macrocell (ETM) and Embedded Trace Buffer (ETB)

To support real-time trace, the ARM926EJ-S processor provides an interface to enable connection of an embedded trace macrocell (ETM). The ARM926ES-J subsystem in the DM6441 also includes the embedded trace buffer (ETB). The ETM consists of two parts:
Trace port provides real-time trace capability for the ARM9.
Triggering facilities provide trigger resources, which include address and data comparators, counter, and sequencers.
The DM6441 trace port is not pinned out and is instead only connected to the embedded trace buffer. The ETB has a 4K-byte buffer memory. ETB enabled debug tools are required to read/interpret the captured trace data.

2.3.14 Power Management

DM6441 has several means of managing power consumption. There is extensive use of clock gating, which reduces the power used by global device clocks and individual peripheral clocks. Clock management can be utilized to reduce clock frequencies in order to reduce switching power. For more details on power management techniques, see Section 3, Device Configurations, Section 6, Peripheral and Electrical Specifications, and see the TMS320DM644x DMSoC ARM Subsystem Reference Guide (literature number SPRUE14).
DM6441 gives the programmer full flexibility to use any and all of the previously mentioned capabilities to customize an optimal power management strategy. Several typical power management scenarios are described in the following sections.

64KB unified mapped RAM/cache (L2)
Little endian

2.4.1 C64x+ DSP CPU Description

www.ti.com
The C64x+ central processing unit (CPU) consists of eight functional units, two register files, and two data paths as shown in Figure 2-1. The two general-purpose register files (A and B) each contain 32 32-bit registers for a total of 64 registers. The general-purpose registers can be used for data or can be data address pointers. The data types supported include packed 8-bit data, packed 16-bit data, 32-bit data, 40-bit data, and 64-bit data. Values larger than 32 bits, such as 40-bit-long or 64-bit-long values are stored in register pairs, with the 32 LSBs of data placed in an even register and the remaining eight or 32 MSBs in the next upper register (which is always an odd-numbered register).
The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing one instruction every clock cycle. The .M functional units perform all multiply operations. The .S and .L units perform a general set of arithmetic, logical, and branch functions. The .D units primarily load data from memory to the register file and store results from the register file into memory.
The C64x+ CPU extends the performance of the C64x core through enhancements and new features. Each C64x+ .M unit can perform one of the following each clock cycle: one 32 x 32 bit multiply, one 16 x
32 bit multiply, two 16 x 16 bit multiplies, two 16 x 32 bit multiplies, two 16 x 16 bit multiplies with add/subtract capabilities, four 8 x 8 bit multiplies, four 8 x 8 bit multiplies with add operations, and four 16 x 16 multiplies with add/subtract capabilities (including a complex multiply). There is also support for Galois field multiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs and modems require complex multiplication. The complex multiply (CMPY) instruction takes four 16-bit inputs and produces a 32-bit real and a 32-bit imaginary output. There are also complex multiplies with rounding capability that produces one 32-bit packed output that contain 16-bit real and 16-bit imaginary values. The 32 x 32 bit multiply instructions provide the extended precision necessary for audio and other high-precision algorithms on a variety of signed and unsigned 32-bit data types.
The .L or (Arithmetic Logic Unit) now incorporates the ability to do parallel add/subtract operations on a pair of common inputs. Versions of this instruction exist to work on 32-bit data or on pairs of 16-bit data performing dual 16-bit add and subtracts in parallel. There are also saturated forms of these instructions.

The C64x+ core enhances the .S unit in several ways. In the C64x core, dual 16-bit MIN2 and MAX2 comparisons were only available on the .L units. On the C64x+ core they are also available on the .S unit which increases the performance of algorithms that do searching and sorting. Finally, to increase data packing and unpacking throughput, the .S unit allows sustained high performance for the quad 8-bit/16-bit and dual 16-bit instructions. Unpack instructions prepare 8-bit data for parallel 16-bit operations. Pack instructions return parallel results to output precision including saturation support.
Other new features include:
SPLOOP - A small instruction buffer in the CPU that aids in creation of software pipelining loops where
Compact instructions - The native instruction size for the C6000 devices is 32 bits. Many common

2.4.3 Peripherals

The DSP has controllability for the following peripherals:
VICP
EDMA3
ASP
Two Timers (Timer 0 and Timer1) that can each be configured as one 64-bit or two 32-bit timers

2.4.4 DSP Interrupt Controller

The DSP interrupt controller accepts device interrupts and appropriately maps them to available DSP interrupts. The DSP interrupt controller is briefly described in this document in the Interrupts section. For more detailed on the DSP interrupt controller, see the TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide (literature number SPRU732).

2.5 Memory Map Summary

Table 2-3 shows the memory map address ranges of the device. Table 2-4 depicts the expanded map of
the configuration space (0x0180 0000 through 0x0FFF FFFF). The device has multiple on-chip memories associated with its two processors and various subsystems. To help simplify software development a unified memory map is used where possible to maintain a consistent view of device resources across all bus masters.

2.6 Pin Assignments

Extensive use of pin multiplexing is used to accommodate the largest number of peripheral functions in the smallest possible package. Pin multiplexing is controlled using a combination of hardware configuration at device reset and software programmable register settings. For more information on pin muxing, see Section 3.5.2, Multiplexed Pin Configurations, of this document.

2.6.1 Pin Map (Bottom View)

Figure 2-2 through Figure 2-5 show the bottom view of the package pin assignments in four quadrants (A,
B, C, and D).

2.8.1 Development Support

TI offers an extensive line of development tools for the SoC platform, including tools to evaluate the performance of the processors, generate code, develop algorithm implementations, and fully integrate and debug software and hardware modules. The tool's support documentation is electronically available within the Code Composer Studio™ Integrated Development Environment (IDE).
The following products support development of SoC-based applications:
Software Development Tools:
Code Composer Studio™ Integrated Development Environment (IDE): including Editor C/C++/Assembly Code Generation, and Debug plus additional development tools Scalable, Real-Time Foundation Software (DSP/BIOS™), which provides the basic run-time target
software needed to support any SoC application.
Hardware Development Tools:
Extended Development System (XDS™) Emulator For a complete listing of development-support tools for the SoC platform, visit the Texas Instruments
web site on the Worldwide Web at http://www.ti.com uniform resource locator (URL). For information on pricing and availability, contact the nearest TI field sales office or authorized distributor.

2.8.2 Device and Development-Support Tool Nomenclature

www.ti.com
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP devices and support tools. Each DSP commercial family member has one of three prefixes: TMX, TMP, or TMS (e.g., TMX320DM6441ZWT). Texas Instruments recommends two of three possible prefix designators for its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering prototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS).
Device development evolutionary flow: TMX Experimental device that is not necessarily representative of the final device's electrical
specifications.
TMP Final silicon die that conforms to the device's electrical specifications but has not completed
quality and reliability verification.
TMS Fully-qualified production device. Support tool development evolutionary flow:
TMDX Development-support product that has not yet completed Texas Instruments internal
qualification testing.
TMDS Fully qualified development-support product. TMX and TMP devices and TMDX development-support tools are shipped against the following
disclaimer: "Developmental product is intended for internal evaluation purposes." TMS devices and TMDS development-support tools have been characterized fully, and the quality and
reliability of the device have been demonstrated fully. TI's standard warranty applies. Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard
production devices. Texas Instruments recommends that these devices not be used in any production system because their expected end-use failure rate still is undefined. Only qualified production devices are to be used.

3.2.1 Power Configurations at Reset

As described in Section 6.3.1.3, DM6441 Power and Clock Domains, the DM6441 has two power domains: Always On and DSP. There is a shorting switch between the two power domains that must be opened when the DSP domain is powered off and closed when the DSP domain is powered on.
The CHP_SHRTSW register, shown in Figure 3-1, controls the shorting switch between the device always-on and DSP power domains. This switch should be enabled after powering-up the DSP domain. Setting the DSPPWRON bit to a value of 1 closes (enables) the switch and enables the DSP power domain. The default switch value is determined by the DSP_BT configuration input. If DSP self boot is selected (DSP_BT=1), the DSP will be powered-up and DSPPWRON will be set to a value of 1. For ARM boot operation (DSP_BT=0), DSPPWRON will be set to the disable value of 0 and must be set by the ARM before the DSP domain power is turned on.

3.3.2 ARM Boot

The DM6441 ARM can boot from EMIFA, internal ROM (NAND, SPI), UART0, or HPI, as determined by the setting of the BTSEL[1:0] pins. The BTSEL[1:0] pins are read by the ARM ROM boot loader (RBL) to further define the ROM boot mode. The ARM boot modes are summarized in Table 3-6.
Table 3-6. ARM Boot Modes
BTSEL1 BTSEL0 Boot Mode ARM Reset Brief Description
0 0 ARM NAND, SPI RBL 0x0000 4000 Up to 14 K-bytes secondary boot loader through NAND with up

host.
When the BTSEL[1:0] pins are set to the ARM EMIFA external boot ("01"), the ARM immediately begins executing code from the EMIFA EM_CS2 memory space (0x0200 0000). When the BTSEL[1:0] pins indicate a condition other than the ARM EMIFA external boot (!01), the RBL begins execution.
ARM NAND/SPI boot mode has the following features:
Loads a secondary user boot loader (UBL) from NAND/SPI flash to ARM internal RAM (AIM) and transfers control to the user software.
Support for NAND with page sizes up to 2048 bytes.
Support for error correction when loading UBL
Support for up to 14KB UBL
Optional, user selectable, support for use of DMA, I-cache, and PLL enable while loading UBL
ARM UART boot mode has the following features:
Loads a secondary UBL via UART0 to AIM and transfers control to the user software.
Support for up to 14KB UBL
ARM HPI boot mode has the following features:
No support for a full firmware boot. Instead, waits for external host ot load a secondary UBL via HPI to AIM and transfers control to the user software.
Support for up to 14KB UBL.

3.3.3 DSP Boot

For C64x+ booting, the state of the DSP_BT pin is sampled at reset. If DSP_BT is low, the ARM will be the master of C64x+ and control booting (host-boot mode). If DSP_BT is high, the C64x+ will boot itself coming out of device reset (self-boot mode). Table 3-7 shows a summary of the DSP boot modes.

register. HPI loads code into the DM6441 memory map with the entry point set to the memory location specified in the DSPBOOTADDR register. Once the HPI completes loading the code, the ARM should release the DSP from reset.
3.3.3.1 Host-Boot Mode
In host boot mode, the ARM is the master and controls the reset and boot of the C64x+. The C64x+ DSP remains powered-off after device reset. The ARM is responsible for enabling power to the C64x+ and releasing it from reset (PSC MMR bits: MDCTL[39].LRST and MRSTOUT1.MRSTz[39]). Prior to releasing the C64x+ reset, the ARM must program the address from which the C64x+ will begin execution in the DSPBOOTADDR register.
3.3.3.2 Self-Boot Mode
In self-boot mode, the C64x+ power domain is turned on and the C64x+ DSP is released from reset without ARM intervention. The C64x+ begins execution from the default EMIFA address (0x4220 0000) contained within the DSPBOOTADDR register. The C64x+ begins execution with instruction (L1P) cache enabled.

3.4 Configurations at Reset

The following sections give information on configuration settings for the device at reset.

3.4.1 Device Configuration at Device Reset

Table 3-8 shows a summary of device inputs required for booting the ARM and DSP, and configuring
EMIFA data and address bus widths for proper operation of the device at the rising edge of the RESET input.

‘00’ indicates ARM boots from ROM (NAND/SPI Flash). ‘01’ indicates that ARM boots from EMIFA (NOR Flash). ‘10’ indicates that the ARM boots from the HPI (ROM) ‘11’ indicates that ARM boots from ROM (UART0).
‘0’ sets ARM boot of C64x+. ‘1’ sets C64x+ self boot.
‘0’ sets EMIFA to 8-bit data bus width ‘1’ sets EMIFA to 16-bit data bus width.
See the GPIO and EMIFA Multiplexing tables (Table 3-9, Table 3-10, and Table 3-11) for details.

3.4.2 Peripheral Selection at Device Reset

As briefly mentioned in Table 3-8, the state of the AEAW[4:0] pins captured at reset configures the number of EMIFA address pins required for device boot. These values are stored in the AEAW field of the PINMUX0 register. At reset, this provides proper addressing for external boot. Unused address pins are available for use as GPIO. The register settings are software programmable after reset. Table 3-9,
Table 3-10, and Table 3-11 show the AEAW[4:0] bit settings and the corresponding multiplexing for
EMIFA address and GPIO pins. The number of EMIFA address bits enabled is configurable from 0 to 23. EM_BA[1] and EM_A[21:0] pins
that are not assigned to another peripheral and not enabled as address signals become GPIO pins. The enabled address pins are always contiguous from EM_BA[1] upwards and address bits cannot be skipped. The exception to this are the EM_A[2:1] pins. EM_A[2:1] are usable as the ALE and CLE signals for the NAND Flash mode of EMIFA and are always enabled as EMIFA pins. If an address width of 0 is selected, this still allows a NAND Flash to be accessed. Also, selecting an address width of 2, 3, or 4 (AEAW[4:0] = 00010, 00011, or 00100) always results in 4 address outputs. For these and other address bit enable settings, see the GPIO and EMIFA Multiplexing tables (Table 3-9, Table 3-10, and Table 3-11).

3.5 Configurations After Reset

The following sections give the details on configuring the device after reset.

3.5.1 Switched Central Resource (SCR) Bus Priorities

Prioritization within the switched central resource (SCR) is programmable for each master. The register bit fields and default priority levels for DM6441 bus masters are shown in Table 3-12. The priority levels should be tuned to obtain the best system performance for a particular application. Lower values indicate higher priority. For most masters, their priority values are programmed at the system level by configuring the MSTPRI0 and MSTPRI1 registers. Details on the MSTPRI0/1 registers are shown in Figure 3-5 and
Figure 3-6. The C64x+, VPSS, and EDMA3 masters contain registers that control their own priority values.

3.5.2 Multiplexed Pin Configurations

There are numerous multiplexed pins that are shared by more than one peripheral. Some of these pins are configured by external pullup/pulldown resistors only at reset, and others are configured by software. As described in detail in Section 3.4.1, Device Configuration at Device Reset, and Section 3.4.2, Peripheral Selection at Device Reset, hardware configurable multiplexed pins are programmed by external pullup/pulldown resistors at reset to set the initial functionality of pins for use by a single peripheral. After reset, software configurable multiplexed pins are programmable through memory mapped registers (MMR) to allow the switching of pin functionalities during run-time. See Section 3.5.3, Peripheral Selection After Device Reset, for more details on the register settings.
A summary of the pin multiplexing is shown in Table 3-13. The EMAC peripheral shares pins with the 3.3V GPIO pins. The VLYNQ pins overlap upper EMIFA address pins resulting in a reduced EMIFA address range as the VLYNQ width is increased. The ATA peripheral shares data lines and some control signals with EMIFA. The ATA DMA pins are multiplexed with UART1. The ASP, UART0/1/2, SPI, I2C, and PWM0/1/2 all default to GPIO pins when not enabled. The VPBE function of the VPSS requires additional pins to implement the RGB888 mode. These are multiplexed with GPIOs.

3.5.6.3 VPBE (RGB666 and RGB888) and GPIO Pin Multiplexing
Use of the RGB666 and RGB888 modes of the VPBE requires enabling RGB pins as shown in Table 3-19 and Table 3-20. Enabling PWM2, PWM1, CCD, and LCD functionality overrides the RGB modes. RGB666 interface pin functionality requires setting the RGB666 PINMUX0 register bit field to ‘1’ and PINMUX1 register bit fields PWM2 and PWM1 to ‘0’. Proper RGB888 interface operation requires setting PINMUX0 register bit field RGB888 to ‘1’ and bit fields PWM2, PWM1, CFLDEN, and LFLDEN must be set to ‘0’.

3.5.6.4 ATA, EMIFA, UART1, SPI, and GPIO Pin Multiplexing
The ATA peripheral shares pins with the EMIFA and UART1 as seen in Table 3-21. If ATA pin functionality is enabled by setting the ATAEN bit field, the ATA module will drive the EMIFA data and control pins. Enabling UART1 disables the use of the ATA DMARQ and DMACK signals and thus only allows the ATA module to use PIO mode. The ATA HDDIR buffer direction control bit field works in conjunction with the HDIREN enable bit field to allow the ATA pins to still be used as a GPIO or SPI_EN1 if the buffer is not being used (i.e. for compact flash). This multiplexing is shown in Table 3-22. When ATAEN=0 and HDIREN=1 it indicates that the ATA interface has been disabled so that the EMIFA can be used, but the ATA buffers are still present. HDDIR is driven low in this situation to ensure that the ATA buffers drive away from DM6441 and don’t cause bus contention with the EMIFA. Note that switching between EMIFA and ATA (clearing or setting ATAEN) must be carefully performed to prevent bus contention. Since the ATA device can be a bus master, software must ensure that all outstanding DMA requests have completed before clearing the ATAEN bit.

3.5.6.5 VLYNQ, EMIFA, and GPIO Pin Multiplexing
Table 3-23 and Table 3-24 show the VLYNQ pin control and multiplexing. If VLYNQ is disabled
(VLYNQEN=0), the AECS5 and AECS4 bits select between the GPIO[8] / EMIFA EM_CS5 and GPIO[9] / EMIFA EM_CS4 functions, and the AEAW field determines the partitioning between GPIO and the upper EMIFA address pins. If VLYNQ is enabled (VLYNQEN=1), VLYNQ_CLOCK, VLYNQ_TXD0, and VLYNQ_RXD0 are always selected. The VLYNQ_SCRUN function is only enabled if VLYNQEN=1 and VLSCREN=1 (VLSCREN overrides AECS4). The remaining VLYNQ TX/RX pins are selected based on the VLYNQWD value. Unselected VLYNQ TX/RX pins will function as either GPIO or EMIFA address based on the AEAW value.

3.5.6.9 UART, VPFE, ATA, and GPIO Pin Multiplexing
Each UART has independent pin multiplexing control bits in the PINMUX1 register. The UART2 peripheral may be used with or without the flow control signals. Table 3-30 shows how UART2 selection reduces the width of the VPFE interface.
Setting the UART1 bit enables UART1 transmit and receive pin functionality. Since these are shared with the ATA DMA handshake signals, enabling UART1 effectively disables the ATA DMA mode. However, ATA PIO mode is still supported with UART1 enabled. This is shown in Table 3-31. If the ATA module is not enabled, the pins are always configured for use by UART1.

3.5.6.10 HPI and EMIFA/ATA Pin Multiplexing
When the HPIEN bit is set, the HPI module is given control of most of the EMIFA/ATA control pins as well as the EMIFA/ATA data bus. Table 3-33 shows which pins the HPI controls. HPIEN is set to 1 when the state of the BTSEL[1:0] pins = 10 is latched at the rising edge of reset. Also, this bit can be manipulated after reset by software. When the ATAEN bit is set and HPIEN is 0, the ATA mode of operation for pins shared with the HPI is available. EMIFA mode functionality for the shared HPI pins is set when both HPIEN and ATAEN are '0'.

3.6 Emulation Control

The flexibility of the DM6441 architecture allows either the ARM or DSP to control the various peripherals (setup registers, service interrupts, etc.). While this assignment is purely a matter of software convention, during an emulation halt it is necessary for the device to know which peripherals are associated with the halting processor so that only those modules receive the suspend signal. This allows peripherals associated with the other (unhalted) processor to continue normal operation. The SUSPSRC register indicates the emulation suspend source for those peripherals which support emulation suspend. The SUSPSRC register format is shown in Figure 3-9. Brief details on the peripherals which correspond to the register bits is given in Table 3-34. When the associated SUSPSRC bit is ‘0’, the peripheral’s emulation suspend signal is controlled by the ARM emulator and when set to ‘1’ it is controlled by the DSP emulator.

4 System Interconnect

On the DM6441 device, the C64x+ megamodule, the ARM subsystem, the EDMA3 transfer controllers, and the system peripherals are interconnected through a switch fabric architecture (shown in Figure 4-1). The switch fabric is composed of multiple switched central resources (SCRs) and multiple bridges. The SCRs establish low-latency connectivity between master peripherals and slave peripherals. Additionally, the SCRs provide priority-based arbitration and facilitate concurrent data movement between master and slave peripherals. Through SCR, the ARM subsystem can send data to the DDR2 Memory Controller without affecting a data transfer between the EMAC and L2 memory. Bridges are mainly used to perform bus-width conversion as well as bus operating frequency conversion. For example, in Figure 4-1, Bridge 8 performs a frequency conversion between a bus operating at DSP/6 clock rate and a bus operating at DSP/3 clock rate. Furthermore, Bridge 3 performs a bus-width conversion between a 64-bit bus and a 32-bit bus.
The C64x+ megamodule, the ARM subsystem, the EDMA3 transfer controllers, and the various system peripherals can be classified into two categories: master peripherals and slave peripherals. Master peripherals are typically capable of initiating read and write transfers in the system and do not rely on the EDMA3 or on a CPU to perform transfers to and from them. The system master peripherals include the C64x+ megamodule, the ARM subsystem, the EDMA3 transfer controllers, CF/ATA, VLYNQ, EMAC, USB, and VPSS. Not all master peripherals may connect to all slave peripherals. The supported connections are designated by an X in Table 4-1.

4.1 System Interconnect Block Diagram

Figure 4-1 displays the DM6441 system interconnect block diagram. The following is a list that helps
interpret this diagram:
The direction of the arrows indicates either bus master or bus slave.
The arrow originates at a bus master and terminates at a bus slave.
The direction of the arrows does not indicate the direction of data flow. Data flow is typically bi-directional for each of the documented bus paths.
The pattern of each arrow's line indicates the clock rate at which it is operating, either DSP/2, DSP/3, or DSP/6 clock rate.
Some peripherals may have multiple instances shown in the diagram. A peripheral may have multiple instances shown for a variety of reasons, some of which are described below:
– The peripheral/module has master port(s) for data transfers, as well as slave port(s) for register
access, data access, and/or memory access. Examples of these peripherals are C64x+ megamodule, EDMA3, CF/ATA, USB, EMAC, VPSS, VLYNQ, and HPI.
– The peripheral/module has a master port as well as slave memories. Examples of these are the
C64x+ megamodule and the ARM subsystem.

6.1.1.2 Timing Parameters and Board Routing Analysis
The timing parameter values specified in this data manual do not include delays by board routings. As a good board design practice, such delays must always be taken into account. Timing values may be adjusted by increasing/decreasing such delays. TI recommends utilizing the available I/O buffer information specification (IBIS) models to analyze the timing characteristics correctly. To properly use IBIS models to attain accurate timing analysis for a given system, see the Using IBIS Models for Timing Analysis application report (literature number SPRA839). If needed, external logic hardware such as buffers may be used to compensate any timing differences.
For the DDR2 memory controller interface, it is not necessary to use the IBIS models to analyze timing characteristics. TI provides a PCB routing rules solution that describes the routing rules to ensure the DDR2 memory controller interface timings are met. See the Implementing DDR2 PCB Layout on the TMS320DM644x DSP Application Report (literature number SPRAAC5).

6.2 Recommended Clock and Control Signal Transition Behavior

All clocks and control signals should transition between VIHand VIL(or between VILand VIH) in a monotonic manner.

6.3.1 Power-Supply Sequencing

The DM6441 includes two core supplies — CVDDand CV DV
The core supply power-up sequence is dependent on the DSP boot mode selected at reset. If the DSP boot mode is configured as self-boot mode, then both core supplies must be powered up at the same time.
If the DSP boot mode is configured as host-boot, where the ARM boots the DSP, the two core supplies may be ramped simultaneously or powered up separately. When powered up separately, the CV supply must not be ramped prior to the CVDDsupply. The CV shorting switch is closed (enabled). Prior to powering up the CV not driven to ground. Table 6-1 and Figure 6-4 describe the power-on sequence timing requirements for DSP host-boot mode.
To minimize the voltage difference between these two core supplies, a single regulator source must be used to power the CVDDand CV

6.3.1.1 Power-Supply Design Considerations
Core and I/O supply voltage regulators should be located close to the DSP (or DSP array) to minimize inductance and resistance in the power delivery path. Additionally, when designing for high-performance applications utilizing the DM6441 device, the PC board should include separate power planes for core, I/O, and ground, all bypassed with high-quality low-ESL/ESR capacitors.
6.3.1.2 Power-Supply Decoupling
In order to properly decouple the supply planes from system noise, place as many capacitors (caps) as possible close to DM6441. Assuming 0603 caps, the user should be able to fit a total of 60 caps, 30 for the core supplies and 30 for the I/O supplies. These caps need to be close to the DM6441 power pins, no more than 1.25 cm maximum distance to be effective. Physically smaller caps, such as 0402, are better because of their lower parasitic inductance. Proper capacitance values are also important. Small bypass caps (near 560 pF) should be closest to the power pins. Medium bypass caps (220 nF or as large as can be obtained in a small package) should be next closest. TI recommends no less than eight small and eight medium caps per supply be placed immediately next to the BGA vias, using the "interior" BGA space and at least the corners of the "exterior".
Larger caps for each supply can be placed further away for bulk decoupling. Large bulk caps (on the order of 100 mF) should be furthest away, but still as close as possible. Large caps for each supply should be placed outside of the BGA footprint.
Any cap selection needs to be evaluated from a yield/manufacturing point-of-view. As with the selection of any component, verification of capacitor availability over the product’s production lifetime should be considered.

6.3.1.3 DM6441 Power and Clock Domains
DM6441 includes two separate power domains: "Always On" and "DSP". The "Always On" power domain is always on when the chip is on. The "Always On" domain is powered by the VDDpins of the DM6441. The majority of the DM6441's modules lie within the "Always On" power domain. A separate domain called the "DSP" domain houses the C64x+ and VICP. The "DSP" domain is not always on. The "DSP" power domain is powered by the CV
pins of the DM6441. Table 6-3 provides a listing of the DM6441 power
DDDSP
and clock domains. Two primary reference clocks are required for the DM6441 device. These can either be crystal input or
driven by external oscillators. A 27-MHz crystal is recommended for the system PLLs, which generate the internal clocks for the ARM, DSP, coprocessors, peripherals (including imaging peripherals), and EDMA3. The recommended 27-MHz input enables the use of the video DACs to drive NTSC/PAL television signals at the proper frequencies. A 24-MHz crystal is also required if the USB peripheral is to be used. For further description of the DM6441 clock domains, see Table 6-4 (DM6441 Clock Domains) and Figure 6-6 (PLL1 and PLL2 Clock Domain Block Diagram).

6.3.1.4 Power and Sleep Controller (PSC) Module
The power and sleep controller (PSC) controls DM6441 device power by turning off unused power domains or gating off clocks to individual peripherals/modules. The PSC consists of a global PSC (GPSC) and a set of Local PSCs (LPSCs). The GPSC contains memory mapped registers, power domain control, PSC interrupt control, and a state machine for each peripheral/module. An LPSC is associated with each peripheral/module and provides clock and reset control. The GPSC controls all of DM6441’s LPSCs. The ARM subsystem does not have an LPSC module. ARM sleep mode is accomplished through the wait for interrupt instruction. The LPSCs for DM6441 are shown in Table 6-5. The PSC Register memory map is given in Table 6-6. For more details on the PSC, see Section 2.8.3, Documentation Support, for the TMS320DM644x DMSoC ARM Subsystem Reference Guide (literature number SPRUE14).
