RTEMS 4.6.1 On-Line Library

RTEMS Intel i386 Applications Supplement

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:

• 386 Programmer's Reference Manual, Intel, Order No. 230985-002.
• 386 Microprocessor Hardware Reference Manual, Intel, Order No. 231732-003.
• 80386 System Software Writer's Guide, Intel, Order No. 231499-001.
• 80387 Programmer's Reference Manual, Intel, Order No. 231917-001.

It is highly recommended that the i386 RTEMS application developer obtain and become familiar with Intel's 386 Programmer's Reference Manual.
