|
|
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 ARM architecture dependencies
|
|
in this port of RTEMS. The ARM family has a wide variety
|
|
of implementations by a wide range of vendors. Consequently,
|
|
there are 100's of CPU models within it.
|
|
|
|
It is highly recommended that the ARM
|
|
RTEMS application developer obtain and become familiar with the
|
|
documentation for the processor being used as well as the
|
|
documentation for the ARM architecture as a whole.

For information on the ARM architecture,
|
|
refer to the following documents available from Arm, Limited
|
|
(@file{http//www.arm.com/}). There does not appear to
|
|
be an electronic version of a manual on the architecture
|
|
in general on that site. The following book is a good
|
|
resource:
