嵌入式软件自动代码生成和代码整合方法研究

Research of Code Auto-Generation and Integration for the Embedded Software

嵌入式软件代码自动生成的开发方法正在逐步取代手工编程,但是自动代码生成工具只对少数微控制器提供了完整支持,使这种方法的普及应用受到了很大的局限。笔者通过对Sim-ulink/Stateflow及RTWEC(实时工作间嵌入式代码生成器)工具软件的分析研究,提出了一种代码自动生成和代码整合的方法。通过构建基于Simulink的仿真模型,可自动生成优化的嵌入式实时仿真代码、在线调整模型参数并监视仿真数据。本方法对于使用任意型号微控制器的嵌入式软件开发都将适用,并且通过在汽车电动天窗控制软件开发实例中的应用,表明这种方法可行且易于实施。

Code auto-generation is gradually replacing manual programming in the embedded software development. However, the present code auto-generation tools support only a few mi- crocontrollers, which results in great restriction for their wide application. By analyzing the Sim- ulink/Stateflow and RTWEC tool software, this paper presents a method for code auto-genera- tion and integration, which can be applied in the embedded software development for any type of microcontroller. Using this method, simulation models are constructed rapidly and model parame- ters are adjusted on-line. This method was applied in developing the embedded software for auto- motive sunroof control. The result shows that it is feasible and easy to implement.
