Abstract

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.<>

在嵌入式系统设计中使用SDL:一个基于嵌入式系统应用软件生成实时操作系统pSOS的工具

本文提出了一种利用规范与描述语言(SDL)设计和实现实时嵌入式系统的有效方法。我们还讨论了基于SDL的设计工具(SDT) CASE工具环境的配套内核的实现，通过应用定义的映射转换规则来生成基于操作系统的实时pSOS多任务应用软件。由于SDL是一种正式的规范和描述语言，在CASE环境SDT的支持下，系统的主要部分可以在系统开发的早期阶段进行分析、模拟、验证和验证。由于系统中的多个并发状态机而产生的并发性保留在目标运行时环境中。由于SDL描述的系统使用消息传递，因此可以相对容易地从中派生分布式版本。为了强调使用SDL而不会显著影响内存和响应时间(速度)的建议方法，我们展示了从AccessControl系统的pSOS实现中获得的结果。我们还概述了一些我们正在继续努力的领域。
