GENERAL DESCRIPTION
ADSP-TS203S
The ADSP-TS203S TigerSHARC processor is an ultrahigh performance, static superscalar processor optimized for large signal
processing tasks and communications infrastructure. The processor combines very wide memory widths with dual
computation blocks—supporting floating-point (IEEE 32-bit
and extended precision 40-bit) and fixed-point (8-, 16-, 32-, and
64-bit) processing—to set a new standard of performance for
digital signal processors. The TigerSHARC static superscalar
architecture lets the processor execute up to four instructions
each cycle, performing 24 fixed-point (16-bit) operations or six
floating-point operations.
Four independent 128-bit wide internal data buses, each connecting to the four 1M bit memory banks, enable quad-word
data, instruction, and I/O access and provide 28G bytes per second of internal memory bandwidth. Operating at 500 MHz, the
ADSP-TS203S processor’s core has a 2.0 ns instruction cycle
time. Using its single-instruction, multiple-data (SIMD) features, the processor can perform four billion 40-bit MACS or
one billion 80-bit MACS per second. Table 1 shows the processor’s performance benchmarks.

*
The TigerSHARC uses a Static Superscalar
architecture. This
architecture is superscalar in that the ADSP-TS203S processor’s
core can execute simultaneously from one to four 32-bit
instructions encoded in a very large instruction word (VLIW)
instruction line using the processor’s dual compute blocks.
Because the processor does not perform instruction reordering
at runtime—the programmer selects which operations will execute in parallel prior to runtime—the order of instructions is
static.
With few exceptions, an instruction line, whether it contains
one, two, three, or four 32-bit instructions, executes with a
throughput of one cycle in a 10-deep processor pipeline.
For optimal processor program execution, programmers must
follow the processor’s set of instruction parallelism rules when
encoding an instruction line. In general, the selection of instructions that the processor can execute in parallel each cycle
depends both on the instruction line resources each instruction
requires and on the source and destination registers used in the
instructions. The programmer has direct control of three core
components—the IALUs, the compute blocks, and the program
sequencer.
The ADSP-TS203S processor, in most cases, has a two-cycle
execution pipeline that is fully interlocked, so—whenever a
computation result is unavailable for another operation dependent on it—the processor automatically inserts one or more stall
cycles as needed. Efficient programming with dependency-free
instructions can eliminate most computational and memory
transfer data dependencies.
In addition, the processor supports SIMD operations two
ways—SIMD compute blocks and SIMD computations. The
programmer can load both compute blocks with the same data
(broadcast distribution) or different data (merged distribution).

ADSP-TS203S
DUAL COMPUTE BLOCKS
The ADSP-TS203S processor has compute blocks that can
execute computations either independently or together as a single-instruction, multiple-data (SIMD) engine. The processor
can issue up to two compute instructions per compute block
each cycle, instructing the ALU, multiplier, or shifter to perform
independent, simultaneous operations. Each compute block can
execute eight 8-bit, four 16-bit, two 32-bit, or one 64-bit SIMD
computations in parallel with the operation in the other block.
These computation units support IEEE 32-bit single-precision
floating-point, extended-precision 40-bit floating point, and
8-, 16-, 32-, and 64-bit fixed-point processing.
The compute blocks are referred to as X and Y in assembly syntax, and each block contains three computational units—an
ALU, a multiplier, a 64-bit shifter—and a 32-word register file.
• Register File—each compute block has a multiported
32-word, fully orthogonal register file used for transferring
data between the computation units and data buses and for
storing intermediate results. Instructions can access the
registers in the register file individually (word-aligned), in
sets of two (dual-aligned), or in sets of four (quad-aligned).
• ALU—the ALU performs a standard set of arithmetic
operations in both fixed- and floating-point formats. It also
performs logic and permute operations.
• Multiplier—the multiplier performs both fixed- and
floating-point multiplication and fixed-point multiply and
accumulate.
• Shifter—the 64-bit shifter performs logical and arithmetic
shifts, bit and bit stream manipulation, and field deposit
and extraction operations.
Using these features, the compute blocks can
• Provide 8 MACS per cycle peak and 7.1 MACS per cycle
sustained 16-bit performance and provide 2 MACS per
cycle peak and 1.8 MACS per cycle sustained 32-bit performance (based on FIR)
• Execute six single-precision floating-point or execute 24
fixed-point (16-bit) operations per cycle, providing
3G FLOPS or 12.0G/s regular operations performance at
500 MHz
• Perform two complex 16-bit MACS per cycle
DATA ALIGNMENT BUFFER (DAB)
The DAB is a quad-word FIFO that enables loading of quadword data from nonaligned addresses. Normally, load instructions must be aligned to their data size so that quad words are
loaded from a quad-aligned address. Using the DAB significantly improves the efficiency of some applications, such as
FIR filters.
DUAL INTEGER ALU (IALU)
The processor has two IALUs that provide powerful address
generation capabilities and perform many general-purpose integer operations. The IALUs are referred to as J and K in assembly
syntax and have the following features:
• Provide memory addresses for data and update pointers
• Support circular buffering and bit-reverse addressing
As address generators, the IALUs perform immediate or indirect (pre- and post-modify) addressing. They perform modulus
and bit-reverse operations with no constraints placed on memory addresses for the modulus data buffer placement. Each
IALU can specify either a single-, dual-, or quad-word access
from memory.
The IALUs have hardware support for circular buffers, bit
reverse, and zero-overhead looping. Circular buffers facilitate
efficient programming of delay lines and other data structures
required in digital signal processing, and they are commonly
used in digital filters and Fourier transforms. Each IALU provides registers for four circular buffers, so applications can set
up a total of eight circular buffers. The IALUs handle address
pointer wraparound automatically, reducing overhead, increasing performance, and simplifying implementation. Circular
buffers can start and end at any memory location.
Because the IALU’s computational pipeline is one cycle deep, in
most cases integer results are available in the next cycle. Hardware (register dependency check) causes a stall if a result is
unavailable in a given cycle.
PROGRAM SEQUENCER
The ADSP-TS203S processor’s program sequencer supports:
• A fully interruptible programming model with flexible programming in assembly and C/C++ languages; handles
hardware interrupts with high throughput and no aborted
instruction cycles
• A 10-cycle instruction pipeline—four-cycle fetch pipe and
six-cycle execution pipe—computation results available
two cycles after operands are available
• Supply of instruction fetch memory addresses; the
sequencer’s instruction alignment buffer (IAB) caches up
to five fetched instruction lines waiting to execute; the program sequencer extracts an instruction line from the IAB
and distributes it to the appropriate core component for
execution
• Management of program structures and program flow
determined according to JUMP, CALL, RTI, RTS instructions, loop structures, conditions, interrupts, and software
exceptions
• Branch prediction and a 128-entry branch target buffer
(BTB) to reduce branch delays for efficient execution of
conditional and unconditional branch instructions and
zero-overhead looping; correctly predicted branches occur
with zero overhead cycles, overcoming the five-to-nine
stage branch penalty
• Compact code without the requirement to align code in
memory; the IAB handles alignment

ADSP-TS203S
Interrupt Controller
The processor supports nested and nonnested interrupts. Each
interrupt type has a register in the interrupt vector table. Also,
each has a bit in both the interrupt latch register and the interrupt mask register. All interrupts are fixed as either levelsensitive or edge-sensitive, except the IRQ3–0
rupts, which are programmable.
The processor distinguishes between hardware interrupts and
software exceptions, handling them differently. When a software exception occurs, the processor aborts all other
instructions in the instruction pipe. When a hardware interrupt
occurs, the processor continues to execute instructions already
in the instruction pipe.
hardware inter-
Flexible Instruction Set
The 128-bit instruction line, which can contain up to four 32-bit
instructions, accommodates a variety of parallel operations for
concise programming. For example, one instruction line can
direct the processor to conditionally execute a multiply, an add,
and a subtract in both computation blocks while it also branches
to another location in the program. Some key features of the
instruction set include:
• Algebraic assembly language syntax
• Direct support for all DSP, imaging, and video arithmetic
types
• Eliminates toggling hardware modes because modes are
supported as options (for example, rounding, saturation,
and others) within instructions
• Branch prediction encoded in instruction; enables zerooverhead loops
• Parallelism encoded in instruction line
• Conditional execution optional for all instructions
• User-defined partitioning between program and data
memory
MEMORY
The processor’s internal and external memory is organized into
a unified memory map, which defines the location (address) of
all elements in the system, as shown in Figure 2.
The memory map is divided into four memory areas—host
space, external memory, multiprocessor space, and internal
memory—and each memory space, except host memory, is subdivided into smaller memory spaces.
The ADSP-TS203S processor internal memory has 4M bits of
on-chip DRAM memory, divided into four blocks of 1M bits
(32K words × 32 bits). Each block—M0, M2, M4, and M6—can
store program instructions, data, or both, so applications can
configure memory to suit specific needs. Placing program
instructions and data in different memory blocks, however,
enables the processor to access data while performing an
instruction fetch. Each memory segment contains a 128K bit
cache to enable single-cycle accesses to internal DRAM.
The four internal memory blocks connect to the four 128-bit
wide internal buses through a crossbar connection, enabling the
processor to perform four memory transfers in the same cycle.
The processor’s internal bus architecture provides a total memory bandwidth of 28G bytes per second, allowing the core and
I/O to access eight 32-bit data-words and four 32-bit instructions each cycle. Additional features are:
• Processor core and I/O access to different memory blocks
in the same cycle
• Processor core access to three memory blocks in parallel—
one instruction and two data accesses
• Programmable partitioning of program and data memory
• Program access of all memory as 32-, 64-, or 128-bit
words—16-bit words with the DAB
EXTERNAL PORT (OFF-CHIP
MEMORY/PERIPHERALS INTERFACE)
The ADSP-TS203S processor’s external port provides the processor’s interface to off-chip memory and peripherals. The
4G word address space is included in the processor’s unified
address space. The separate on-chip buses—four 128-bit data
buses and four 32-bit address buses—are multiplexed at the
SOC interface and transferred to the external port over the SOC
bus to create an external system bus transaction. The external
system bus provides a single 32-bit data bus and a single 32-bit
address bus. The external port supports data transfer rates of
500M bytes per second over the external bus.
The external bus is configured for 32-bit, little-endian operations. Unlike the ADSP-TS201, the ADSP-TS203S processor’s
external port cannot support 64-bit operations; the external bus
width control bits (Bits 21-19) must = 0 in the SYSCON register—all other values are illegal for the ADSP-TS203S. Because
the external port is restricted to 32 bits on the ADSP-TS203S
processor, there are a number of pinout differences between the
ADSP-TS203S and the ADSP-TS201 processors.
The external port supports pipelined, slow, and SDRAM protocols. Addressing of external memory devices and memorymapped peripherals is facilitated by on-chip decoding of high
order address lines to generate memory bank select signals.
The ADSP-TS203S processor provides programmable memory,
pipeline depth, and idle cycle for synchronous accesses, and
external acknowledge controls to interface to pipelined or slow
devices, host processors, and other memory-mapped peripherals with variable access, hold, and disable time requirements.
Host Interface
The ADSP-TS203S processor provides an easy and configurable
interface between its external bus and host processors through
the external port. To accommodate a variety of host processors,
the host interface supports pipelined or slow protocols for processor access of the host as slave or pipelined for host access of
the ADSP-TS203S processor as slave. Each protocol has programmable transmission parameters, such as idle cycles, pipe
depth, and internal wait cycles.

The host can directly read or write the internal memory of the
ADSP-TS203S processor, and it can access most of the processor registers, including DMA control (TCB) registers. Vector
interrupts support efficient execution of host commands.
Multiprocessor Interface
The processor offers powerful features tailored to multiprocessing processor systems through the external port and link ports.
This multiprocessing capability provides the highest bandwidth
for interprocessor communication, including
• Up to eight DSPs on a common bus
• On-chip arbitration for glueless multiprocessing
• Link ports for point-to-point communication
The external port and link ports provide integrated, glueless
multiprocessing support.

ADSP-TS203S
The external port supports a unified address space (see Figure 2)
that enables direct interprocessor accesses of each ADSPTS203S processor’s internal memory and registers. The processor’s on-chip distributed bus arbitration logic provides simple,
glueless connection for systems containing up to eight
ADSP-TS203S processors and a host processor. Bus arbitration
has a rotating priority. Bus lock supports indivisible readmodify-write sequences for semaphores. A bus fairness feature
prevents one processor from holding the external bus too long.
The processor’s two link ports provide a second path for interprocessor communications with throughput of 1G byte per
second. The cluster bus provides 500M bytes per second
throughput—with a total of 1.5G bytes per second interprocessor bandwidth.
SDRAM Controller
The SDRAM controller controls the processor’s transfers of
data to and from external synchronous DRAM (SDRAM) at a
throughput of 32 bits per SCLK cycle using the external port
and SDRAM control pins.
The SDRAM interface provides a glueless interface with standard SDRAMs—16M bits, 64M bits, 128M bits, 256M bits and
512M bits. The processor supports directly a maximum of four
banks of 64M words × 32 bits of SDRAM. The SDRAM interface is mapped in external memory in each processor’s unified
memory map.
• External port block transfers. Four dedicated bidirectional
DMA channels transfer blocks of data between the processor’s internal memory and any external memory or
memory-mapped peripheral on the external bus. Master
mode and handshake mode protocols are supported.
• Link port transfers. Four dedicated DMA channels (two
transmit and two receive) transfer quad-word data only
between link ports and between a link port and internal or
external memory. These transfers only use handshake
mode protocol. DMA priority rotates between the two
receive channels.
• AutoDMA transfers. Two dedicated unidirectional DMA
channels transfer data received from an external bus master
to internal memory or to link port I/O. These transfers only
use slave mode protocol, and an external bus master must
initiate the transfer.
The DMA controller provides these additional features:
• Flyby transfers. Flyby operations only occur through the
external port (DMA channel 0) and do not involve the processor’s core. The DMA controller acts as a conduit to
transfer data from an external I/O device to external
SDRAM memory. During a transaction, the processor
relinquishes the external data bus; outputs addresses and
memory selects (MSSD3–0
IOEN
, and RD/WR strobes; and responds to ACK.
); outputs the IORD, IOWR,
EPROM Interface
The processor can be configured to boot from an external 8-bit
EPROM at reset through the external port. An automatic process (which follows reset) loads a program from the EPROM
into internal memory. This process uses 16 wait cycles for each
read access. During booting, the BMS
EPROM chip select signal. The EPROM boot procedure uses
DMA Channel 0, which packs the bytes into 32-bit instructions.
Applications can also access the EPROM (write flash memories)
during normal operation through DMA.
The EPROM or flash memory interface is not mapped in the
processor’s unified memory map. It is a byte address space limited to a maximum of 16M bytes (24 address bits). The EPROM
or flash memory interface can be used after boot via a DMA.
pin functions as the
DMA CONTROLLER
The ADSP-TS203S processor’s on-chip DMA controller, with
10 DMA channels, provides zero-overhead data transfers without processor intervention. The DMA controller operates
independently and invisibly to the processor’s core, enabling
DMA operations to occur while the processor’s core continues
to execute program instructions.
The DMA controller performs DMA transfers between internal
memory, external memory, and memory-mapped peripherals;
the internal memory of other DSPs on a common bus, a host
processor, or link port I/O; between external memory and external peripherals or link port I/O; and between an external bus
master and internal memory or link port I/O. The DMA controller performs the following DMA operations:
• DMA chaining. DMA chaining operations enable applications to automatically link one DMA transfer sequence to
another for continuous transmission. The sequences can
occur over different DMA channels and have different
transmission attributes.
• Two-dimensional transfers. The DMA controller can
access and transfer two-dimensional memory arrays on any
DMA transmit or receive channel. These transfers are
implemented with index, count, and modify registers for
both the X and Y dimensions.
LINK PORTS (LVDS)
The processor’s two full-duplex link ports each provide additional four-bit receive and four-bit transmit I/O capability,
using low-voltage, differential-signal (LVDS) technology. With
the ability to operate at a double data rate—latching data on
both the rising and falling edges of the clock—running at
250 MHz, each link port can support up to 250M bytes per second per direction, for a combined maximum throughput of
1G byte per second.
The link ports provide an optional communications channel
that is useful in multiprocessor systems for implementing pointto-point interprocessor communications. Applications can also
use the link ports for booting.
Each link port has its own triple-buffered quad-word input and
double-buffered quad-word output registers. The processor’s
core can write directly to a link port’s transmit register and read
from a receive register, or the DMA controller can perform
DMA transfers through four (two transmit and two receive)
dedicated link port DMA channels.
Each link port direction has three signals that control its operation. For the transmitter, LxCLKOUT is the output transmit
clock, LxACKI is the handshake input to control the data flow,
and the LxBCMPO
output indicates that the block transfer is
complete. For the receiver, LxCLKIN is the input receive clock,
LxACKO is the handshake output to control the data flow, and
the LxBCMPI
input indicates that the block transfer is complete. The LxDATO3–0 pins are the data output bus for the
transmitter, and the LxDATI3–0 pins are the input data bus for
the receiver.
Applications can program separate error detection mechanisms
for transmit and receive operations (applications can use the
checksum mechanism to implement consecutive link port
transfers), the size of data packets, and the speed at which bytes
are transmitted.
TIMER AND GENERAL-PURPOSE I/O
The ADSP-TS203S processor has a timer pin (TMR0E) that
generates output when a programmed timer counter has
expired, and four programmable general-purpose I/O pins
(FLAG3–0) that can function as either single-bit input or output. As outputs, these pins can signal peripheral devices; as
inputs, they can provide the test for conditional branching.
For more information on boot options, see the EE-200:
ADSP-TS20x TigerSHARC Processor Boot Loader Kernels Operation on the Analog Devices website (www.analog.com)
CLOCK DOMAINS
The processor uses calculated ratios of the SCLK clock to operate, as shown in Figure 3. The instruction execution rate is equal
to CCLK. A PLL from SCLK generates CCLK which is phaselocked. The SCLKRATx pins define the clock multiplication of
SCLK to CCLK (see Table 4 on Page 11). The link port clock is
generated from CCLK via a software programmable divisor, and
the SOC bus operates at 1/2 CCLK. Memory transfers to external and link port buffers operate at the SOCCLK rate. SCLK also
provides clock input for the external bus interface and defines
the ac specification reference for the external bus signals. The
external bus interface runs at the SCLK frequency. The maximum SCLK frequency is one quarter the internal processor
clock (CCLK) frequency.
RESET AND BOOTING
The processor has three levels of reset:
• Power-up reset – after power-up of the system (SCLK, all
static inputs, and strap pins are stable), the RST_IN
must be asserted (low).
• Normal reset – for any chip reset following the power-up
reset, the RST_IN
• Processor-core reset – when setting the SWRST bit in
EMUCTL, the processor core is reset, but not the external
port or I/O.
For normal operations, tie the RST_OUT
POR_IN
pin.
After reset, the processor has four boot options for beginning
operation:
•Boot from EPROM.
• Boot by an external master (host or another ADSP-TS203S
processor).
•Boot by link port.
• No boot—start running from memory address selected
with one of the IRQ3–0
Using the this option, the processor must start running
from memory when one of the interrupts is asserted.
The processor core always exits from reset in the idle state and
waits for an interrupt. Some of the interrupts in the interrupt
vector table are initialized and enabled after reset.

DEVELOPMENT TOOLS
The ADSP-TS203S processor is supported with a complete set
of CROSSCORE
including Analog Devices emulators and VisualDSP++
opment environment. The same emulator hardware that
supports other TigerSHARC processors also fully emulates the
ADSP-TS203S processor.
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++ run-time library that includes DSP and
mathematical functions. A key point for theses tools is C/C++
code efficiency. The compiler has been developed for efficient
translation of C/C++ code to DSP 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
®
software and hardware development tools,
®
devel-
ADSP-TS203S
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++ IDE lets programmers define and manage
DSP software development. Its dialog boxes and property pages
let programmers configure and manage all of the TigerSHARC
processor 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
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.
VCSE is Analog Devices’ technology for creating, using, and
reusing software components (independent modules of substantial functionality) to quickly and reliably assemble software
applications. It is also used for downloading components from
the Web, dropping them into the application, and publish component archives from within VisualDSP++. VCSE supports
component implementation in C/C++ or assembly language.

ADSP-TS203S
Use the expert linker to visually manipulate the placement of
code and data on the embedded system, view memory use in a
color-coded graphical form, easily move code and data to different areas of the processor or external memory with a drag of the
mouse, and examine runtime 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-TS203S processor 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 TigerSHARC processor family.
Hardware tools include TigerSHARC processor PC plug-in
cards. Third party software tools include DSP libraries, realtime operating systems, and block diagram design tools.
Evaluation Kit
Analog Devices offers a range of EZ-KIT Lite® evaluation platforms to use as a cost-effective method to learn more about
developing or prototyping applications with Analog Devices
processors, platforms, and software tools. Each EZ-KIT Lite
includes an evaluation board along with an evaluation suite of
the VisualDSP++ development and debugging environment
with the C/C++ compiler, assembler, and linker. Also included
are sample application programs, power supply, and a USB
cable. All evaluation versions of the software tools are limited
for use only with the EZ-KIT Lite product.
The USB controller on the EZ-KIT Lite board connects the
board to the USB port of the user’s PC, enabling the
VisualDSP++ evaluation suite to emulate the on-board processor in-circuit. This permits the customer to download, execute,
and debug programs for the EZ-KIT Lite system. It also allows
in-circuit programming of the on-board flash device to store
user-specific boot code, enabling the board to run as a
standalone unit, without being connected to the PC.
With a full version of VisualDSP++ installed (sold separately),
engineers can develop software for the EZ-KIT Lite or any custom-defined system. Connecting one of Analog Devices JTAG
emulators to the EZ-KIT Lite board enables high speed, nonintrusive emulation.
processor must be halted to send data and commands, but once
an operation has been completed by the emulator, the 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 the EE-68: Analog Devices JTAG Emulation Technical Reference on the Analog Devices website (www.analog.com)—

RELATED SIGNAL CHAINS
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. For more information about
this term and related topics, see the “signal chain” entry in the
Glossary of EE Terms on the Analog Devices website.
Analog Devices eases signal processing system development by
providing signal processing components that are designed to
work together well. A tool for viewing relationships between
specific applications and related components is available on the

PIN FUNCTION DESCRIPTIONS
ADSP-TS203S
While most of the ADSP-TS203S processor’s input pins are normally synchronous—tied to a specific clock—a few are
asynchronous. For these asynchronous signals, an on-chip synchronization circuit prevents metastability problems. Use the ac
specification for asynchronous signals when the system design
requires predictable, cycle-by-cycle behavior for these signals.
The output pins can be three-stated during normal operation.
The processor three-states all output during reset, allowing
these pins to get to their internal pull-up or pull-down state.
Some pins have an internal pull-up or pull-down resistor (±30%
tolerance) that maintains a known value during transitions
between different drivers.

DD_IO
ncAddress Bus. The processor issues addresses for accessing memory and peripherals
on these pins. In a multiprocessor system, the bus master drives addresses for
accessing internal memory or I/O processor registers of other ADSP-TS203S
processors. The processor inputs addresses when a host or another processor
accesses its internal memory or I/O processor registers.
ncExternal Data Bus. The processor drives and receives data and instructions on these
pins. Pull-up or pull-down resistors on unused DATA pins are unnecessary.
1
epu
Memory Read. RD is asserted whenever the processor reads from any slave in the
system, excluding SDRAM. When the processor is a slave, RD
is an input and
indicates read transactions that access its internal memory or universal registers. In
a multiprocessor system, the bus master drives RD. RD changes concurrently with
ADDR pins.
1
epu
Write Low. WRL is asserted when the ADSP-TS203S processor writes to the external
bus (host, memory, or processor). An external master (host or processor) asserts WRL
for writing to a processor’s internal memory. In a multiprocessor system, the bus
master drives WRL
is a slave, WRL
. WRL changes concurrently with ADDR pins. When the processor
is an input and indicates write transactions that access its internal
memory or universal registers.
1
epu
Acknowledge. External slave devices can deassert ACK to add wait states to external
memory accesses. ACK is used by I/O devices, memory controllers, and other peripherals on the data phase. The processor can deassert ACK to add wait states to read
and write accesses of its internal memory. The pull-up is 50 on low-to-high transactions and is 500 on all other transactions.
naBoot Memory S elect. BMS is the chip select for boot EPROM or flash memory. During
reset, the processor uses BMS as a strap pin (EBOOT) for EPROM boot mode. In a
multiprocessor system, the processor bus master drives BMS
. For details, see Reset
and Booting on Page 8 and the EBOOT signal description in Table 16 on Page 18.
ncMemory Select. MS0 or MS1 is asserted whenever the processor accesses memory
banks 0 or 1, respectively. MS1–0 are decoded memory address pins that change
concurrently with ADDR pins. When ADDR31:27 = 0b00110, MS0
is asserted. When
ADDR31:27 = 0b00111, MS1 is asserted. In multiprocessor systems, the master
processor drives MS1–0.
ncMemory Select Host. MSH is asserted whenever the processor accesses the host
address space (ADDR31 = 0b1). MSH
is a decoded memory address pin that changes
concurrently with ADDR pins. In a multiprocessor system, the bus master processor
drives MSH.
1
epu
Burst. The current bus master (processor or host) asserts this pin to indicate that it
is reading or writing data associated with consecutive addresses. A slave device can
ignore addresses after the first one and increment an internal address counter after
each transfer. For host-to-processor burst accesses, the processor increments the
address automatically while BRST
is asserted.

STRAP PIN FUNCTION DESCRIPTIONS
Some pins have alternate functions at reset. Strap options set
processor operating modes. During reset, the processor samples
the strap option pins. Strap pins have an internal pull-up or
pull-down for the default value. If a strap pin is not connected to
an overdriving external pull-up, pull-down, or logic load, the
processor samples the default value during reset. If strap pins

Table 18. Maximum Duty Cycle for Input Transient Voltage
The individual values cannot be combined for analysis of a single instance of overshoot or undershoot. The worst case observed value must fall within one of the voltages
specified and the total duration of the overshoot or undershoot (exceeding the 100% case) must be less than or equal to the corresponding
duty cycle.
2
Duty cycle refers to the percentage of time the signal exceeds the value for the 100% case. This is equivalent to the measured duration of a single instance of overshoot or
undershoot as a percentage of the period of occurrence. The practical worst case for period of occurrence for either overshoot or undershoot is 2 × t

TIMING SPECIFICATIONS
With the exception of DMAR3–0, IRQ3–0, TMR0E, and
FLAG3–0 (input only) pins, all ac timing for the ADSP-TS203S
processor is relative to a reference clock edge. Because input
setup/hold, output valid/hold, and output enable/disable times
are relative to a clock edge, the timing data for the
ADSP-TS203S processor has few calculated (formula-based)
values. For information on ac timing, see General AC Timing.
For information on link port transfer timing, see Link Port Low
Voltage, Differential-Signal (LVDS) Electrical Characteristics,
and Timing on Page 29.
General AC Timing
Timing is measured on signals when they cross the 1.25 V level
as described in Figure 13 on Page 28. All delays (in nanoseconds) are measured between the point that the first signal
reaches 1.25 V and the point that the second signal reaches
1.25 V.

The general ac timing data appears in Table 22 and Table 29. All
ac specifications are measured with the load specified in
Figure 34 on Page 36, and with the output drive strength set to

for different load conditions and/or output drive strengths, refer
to Figure 35 on Page 36 through Figure 42 on Page 38 (Rise and
Fall Time vs. Load Capacitance) and Figure 43 on Page 38 (Output Valid vs. Load Capacitance and Drive Strength).

The ac signal specifications (timing parameters) appear in

for the processor apply for the voltage reference levels in

Output Disable Time
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 time for the voltage on the bus
to decay by ΔV is dependent on the capacitive load, C
load current, I
. This decay time can be approximated by the

Output pins are considered to be enabled when they have made
a transition from a high impedance state to when they start driving. The time for the voltage on the bus to ramp by ΔV is

Capacitive Loading
Output valid and hold are based on standard capacitive loads:
30 pF on all pins (see Figure 34). The delay and hold specifications given should be derated by a drive strength related factor
for loads other than the nominal value of 30 pF. Figure 35
through Figure 42 show how output rise time varies with capacitance. Figure 43 graphically shows how output valid varies with
load capacitance. (Note that this graph or derating does not
apply to output disable delays; see Output Disable Time on
Page 35.) The graphs of Figure 35 through Figure 43 may not be
