摘　　要：随着代码自动生成技术的发展,基于文本规范的传统嵌入式软件开发模式逐渐被基于模型的设计方法所取代,代码自动生成技术是基于模型的开发方法中一项核心技术,而MATLAB中RTW工具箱是代码自动生成最优秀的工具,首先对基于RTW的代码自动生成机制进行了分析,研究了VxWorks目标代码的结构及变量命名规则,并从程序实时运行机制方面进行了分析,方便用户对自动生成的代码进行二次开发;采用该技术进行VxWorks嵌入式软件开发,可大大提高开发效率。With the development of auto code generation technology, the traditional embedded software development mode based on text specification is gradually replaced by the development method based on the model. Auto code generation technology is the key element of the development method based on the model and the RTW toolbox in MATLAB is a perfect tool. The RTW-based auto code generation mecha- nism is analyzed, the structure of VxWorks target code and variables naming rules are studied, then the running mechanism of real-time pro- gram is analyzed. It is convenient for users to employ the analyses to develop embedded software. The use of auto code generation technology for embedded software development will greatly enhance the efficiency.
