@unnumbered Preface

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.

For information on the i386 processor, refer to the

following documents:

It is highly recommended that the i386 RTEMS

application developer obtain and become familiar with Intel's

386 Programmer's Reference Manual.
