Ada for closely coupled multiprocessor targets
Pages 450 - 461
Abstract
The techniques for cross-compiling real-time Ada programs for embedded targets are well developed. Generally, these toolsets enable the user to compile and build a program on the host, load it into the target's memories via some form of serial or parallel link, and then run and debug the program under intensive control from the host.
This technology has now been extended by SD to provide similar facilities for a class of closely coupled multiprocessor targets comprising homogeneous microprocessors connected by shared memories. The outcome is that a single Ada program can be distributed across the processors of a multiprocessor target.
This paper describes the general algorithms by which this is achieved, with emphasis given to certain specific solutions for the SD system. The system employs simple, pragmatic solutions in preference to generalised theoretical ones. The paper describes how an Ada program is distributed across a multiprocessor target, both from a user's view and from an implementation view. It describes how a multiprocessor Ada program can be written, built and debugged. Comparisons are also made with other multiprocessor schemes.
The multiprocessor Ada system was developed under a contract placed by MBB on behalf of PANAVIA via the German company TELDIX GmbH. It has been in active use since the middle of 1988 for the development of Ada avionics applications on a special Motorola MC68000 based multiprocessor target developed by TELDIX for the Tornado programme. It is believed to be the first multiprocessor Ada system of its kind in avionics use.
