14 | The Real Time Executive for Multiprocessor Systems (RTEMS) |
---|
15 | is designed to be portable across multiple processor |
---|
16 | architectures. However, the nature of real-time systems makes |
---|
17 | it essential that the application designer understand certain |
---|
18 | processor dependent implementation details. These processor |
---|
19 | dependencies include calling convention, board support package |
---|
20 | issues, interrupt processing, exact RTEMS memory requirements, |
---|
21 | performance data, header files, and the assembly language |
---|
22 | interface to the executive. |
---|
23 | |
---|
24 | This document discusses the ARM architecture dependencies |
---|
25 | in this port of RTEMS. The ARM family has a wide variety |
---|
26 | of implementations by a wide range of vendors. Consequently, |
---|
27 | there are 100's of CPU models within it. |
---|
28 | |
---|
29 | It is highly recommended that the ARM |
---|
30 | RTEMS application developer obtain and become familiar with the |
---|
31 | documentation for the processor being used as well as the |
---|
32 | documentation for the ARM architecture as a whole. |

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