AADL构件到RTLinux平台C代码的转换方法研究*

为了提高嵌入式软件开发的自动化程度,代码自动生成是一种值得采用的有效方法.在研究体系结构分析与设计语言(AADL)和RTLinux(real-time Linux)平台C代码的特性的基础上,提出了AADL构件到RTLinux平台C代码的转换规则；然后用一个实例实现了代码自动生成,从而验证了转换规则的有效性.

Research of transformation method from AADL components to C code in platform of RTLinux

Because the current research about code plagiarism detection mostly based on program source code similarity, lacking of grammatical analysis to code, ignoring the syntax and semantics of the program, can not effectively detect plagiarism to the slight modification of the structure.This paper presented a code plagiarism detection based on the AST. It pre-formated code, analysis lexical and syntax and obtained the corresponding AST. Then it traversed AST to generate code sequences, calculated the similarity of the code sequence and got the code plagiarism detection report. Experimental results show that the approach can verify the C code plagiarism effectively, and it has some versatility and scalability on the C++,Java and other plagiarism detection program code.
