RTEMS CPU Architecture Supplement
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:
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.
