up a total of eight circular buffers. The IALUs handle address
pointer wraparound automatically, reducing overhead, increas-
ing 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. Hard-
ware (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 the
following:
A fully interruptible programming model with flexible pro-
gramming 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 pro-
gram 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 instruc-
tions, 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
Interrupt Controller
The DSP supports nested and nonnested interrupts. Each inter-
rupt 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 level-sensitive or
edge-sensitive, except the IRQ3–0 hardware interrupts, which
are programmable.
The DSP distinguishes between hardware interrupts and soft-
ware exceptions, handling them differently. When a software
exception occurs, the DSP aborts all other instructions in the
instruction pipe. When a hardware interrupt occurs, the DSP
continues to execute instructions already in the instruction pipe.
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 DSP 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 DSP hardware modes because modes
are supported as options (for example, rounding, satura-
tion, and others) within instructions
Branch prediction encoded in instruction; enables zero-
overhead loops
Parallelism encoded in instruction line
Conditional execution optional for all instructions
User-defined partitioning between program and data
memory
DSP MEMORY
The DSP’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 3.
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 sub-
divided 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 DSP 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
DSP to perform four memory transfers in the same cycle. The
DSP’s internal bus architecture provides a total memory band-
width of 28G bytes per second, enabling the core and I/O to
access eight 32-bit data-words and four 32-bit instructions each
cycle. The DSP’s flexible memory structure enables
DSP core and I/O access to different memory blocks in the
same cycle
DSP 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
