|
|
|
|
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 Motorola MC68xxx
|
|
architecture dependencies in this port of RTEMS. The MC68xxx
|
|
family has a wide variety of CPU models within it. The part
|
|
numbers for these models are generally divided into MC680xx and
|
|
MC683xx. The MC680xx models are more general purpose processors
|
|
with no integrated peripherals. The MC683xx models, on the
|
|
other hand, are more specialized and have a variety of
|
|
peripherals on chip including sophisticated timers and serial
|
|
communications controllers.
|
|
|
|
It is highly recommended that the Motorola MC68xxx
|
|
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.
