SUITE56™
DSP SOFTWARE
DEVELOPMENT TOOLS
OVERVIEW
The DSP56300 family of digital signal processors (DSPs)
is fully supported by Motorola’s Suite56 software
development tools. This robust tool suite, which has
helped to develop millions of lines of DSP software,
includes an assembler, linker, simulator, debugger and
several utilities. Suite56 supports developing with
multiple DSPs, ideal for DSP farm applications.
The suite’s full-featured linker is engineered to provide complete control over placement
of code and data in memory, as well as more sophisticated features such as overlays to
allow the user to copy sections of code into program memory while the program is
running. The code is generally stored in slower, less complex memory and copied into
fast memory to be executed, lowering system development costs without sacrificing
execution time.
On the code execution side, the debugger is designed to provide C and assembly
language development support for the simulator, evaluation boards, and user systems,
all from the same intuitive user interface. The debugger can run scripts of commands to
automate frequently executed development tasks.
The Suite56 assembler provides a rich set of features
designed to enable efficient embedded software
development, including support for macros that give the
user the ability to write a sequence of instructions once,
and call the sequence from multiple points in the code
without incurring the overhead of a subroutine call. In
addition, structured assembly is designed to provide
high-level constructs such as looping (“do while”) and
conditional execution (“if then else”) in assembly
language programs.
The Suite56 simulator is a cycle-approximate simulator for the DSP56300 core; it also
simulates peripherals for DSP56300 derivatives. It has sophisticated I/O capabilities and
supports multidevice simulation, an important and convenient feature for developers of
DSP farm-based solutions.
Profiling capabilities are built into the debugger for use with the DSP56300 simulator.
The profiler tracks how much time is spent in each section of code so that developers
can better determine where to optimize the program.
