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 PowerPC architecture
|
|
dependencies in this port of RTEMS.
|
|
|
|
It is highly recommended that the PowerPC RTEMS
|
|
application developer obtain and become familiar with the
|
|
documentation for the processor being used as well as the
|
|
specification for the revision of the PowerPC architecture which
|
|
corresponds to that processor.

@subheading PowerPC Processor Simulator Information
|
|
|
|
PSIM is a program which emulates the Instruction Set Architecture
|
|
of the PowerPC microprocessor family. It is reely available in source
|
|
code form under the terms of the GNU General Public License (version
|
|
2 or later). PSIM can be integrated with the GNU Debugger (gdb) to
|
|
execute and debug PowerPC executables on non-PowerPC hosts. PSIM
|
|
supports the addition of user provided device models which can be
|
|
used to allow one to develop and debug embedded applications using
|
|
the simulator.
|
|
|
|
The latest version of PSIM is made available to the public via
|
|
anonymous ftp at ftp://ftp.ci.com.au/pub/psim or
|
|
ftp://cambridge.cygnus.com/pub/psim. There is also a mailing list
|
|
at powerpc-psim@@ci.com.au.
