|
|
The Real Time Executive for Multiprocessor Systems (RTEMS)
|
|
is designed to be portable across multiple processor
|
|
architectures. However, the nature of real-time systems makes
|
|
it essential that the application designer understand certain
|
|
processor dependent implementation details. These processor
|
|
dependencies include calling convention, board support package
|
|
issues, interrupt processing, exact RTEMS memory requirements,
|
|
performance data, header files, and the assembly language
|
|
interface to the executive.
|
|
|
|
This document discusses the Texas Instrument C3x/C4x
|
|
architecture dependencies in this port of RTEMS. The C3x/C4x
|
|
family has a wide variety of CPU models within it. The following
|
|
CPU model numbers could be supported by this port:
|
|
|
|
@itemize
|
|
@item C30 - TMSXXX
|
|
@item C31 - TMSXXX
|
|
@item C32 - TMSXXX
|
|
@item C41 - TMSXXX
|
|
@item C44 - TMSXXX
|
|
@end itemize
|
|
|
|
Initiially, this port does not include full support for C4x models.
|
|
Primarily, the C4x specific implementations of interrupt flag and
|
|
mask management routines have not been completed.
|
|
|
|
It is highly recommended that the RTEMS application developer obtain
|
|
and become familiar with the documentation for the processor being
|
|
used as well as the documentation for the family as a whole.
