4.3.1
The COFF Macro Assembler translates DSP assembly language source files into
machine language object files. It consists of a macro pre-processor, has a complete
programming restriction checking and prepares the object for full symbolic debugging.
Besides it is sensitive, contains C-like operators and conventions that allow easy
development of code and data structures. The object files generated are compatible to
the Common Object File Format (COFF).
4.3.2
The Linker/Locator combines object files generated by the COFF Macro Assembler into
a single executable COFF object file. As it creates the executable object file, it performs
relocation which means map them to the target systems memory map. Besides it
supports user defined memory classes and enables to locate segments at absolute
locations or relative to other segments and to overlay segments. The linking capability is
very flexible and modular.
4.3.3
Most EPROM programmers do not accept executable COFF object files as input.
Therefore the Object Format Converter translates the COFF file into Intel hex file format
that can be downloaded to any ordinary EPROM programmer.
4.3.4
The C-Compiler is full featured ANSI Standard C-Compiler which accepts C source code
and produces assembler language source code, that can be processed by the COFF
Marco Assembler. It uses a sophisticated optimization pass that employs several
advanced techniques for generating efficient, compact code from C source. Beside the
mixed language environment allows time critical routines to be replaced with very fast
assembly routines for optimum performance with C language environment. Both, in-line
assembly and out-line assembly are supported. For stand alone applications, the
compiler enables to link all code and initialization data into ROM, allowing C code to run
from reset. The C-compiler is fully integrated into the development environment, which
allows the user complete control over C or assembly code during debugging. The
compiler is based on the technology developed by the Free Software Foundation (GNU).
