摘要

We present an efficient method using the Specification and Description Language (SDL) for designing and implementing real-lime embedded systems. We also discuss the implementation of a companion kernel for an SDL based Design Tool (SDT) CASE tool environment to generate real-time OS based pSOS multitasking application software by applying defined mapping translation rules. Since SDL is a formal specification and description language, with the CASE environment SDT support, the major part of a system can be analyzed, simulated, verified, and validated at early stages during system development. The concurrency due to the multiple concurrent state machines in a system is preserved in target run-time environment. Because the SDL described system uses message-passing, a distributed version can be relatively easy to derive from. To emphasize the proposed method using SDL without dramatically compromising the memory and response time (speed), we show the results obtained from pSOS implementation of an AccessControl system. We also outline some areas that we are continuing to work on.
