基于SDL语言代码自动生成技术研究

1.引言目前嵌入式实时系统的复杂度越来越高,自动代码生成技术已成为缩短嵌入式系统开发时间和降低开发成本的主要方法之一,也是近十年软件开发工具研究的热门课题。所谓自动代码生成,即把形式化描述的系统需求转化为特定软硬件平台上基于某一目标语言的系统实现。代码自动生成技术研究虽然已经取得一定成果,也被应用到一些商业工具中,但生成代码的执行效率、与实际软硬件平台的结合等问题限制了其在实际工程中的使用。根据转化程度不同自动代码生成又分为完全的自动代码生成和部分的自动代码生成,本文就基于SDL的完全自动代码生成的关键技术及其对最终代码的影响进行初步探讨。

Research on Automatic Code Generation Based on SDL

As one of the key technology of CASE tools,code auto-generation has a wide application future. However, at present, some of problems limit its application in the practical project, such as executive efficiency of code generation, the combination with the hardware and software and etc. In this paper, the mam factors of code auto-generation are introduced in details. The main parts of the code auto-generation based on SDL and the main factors which will effect the ultimately code performance are analyzed. The improved methods aiming at the different software and hardware platform and application performance are presented.
