基于IDA处理器模块扩充的描述语言建立

摘要

目前的IDA不能支持所有处理器模型的反汇编.为此,给出一种适用于IDA处理器模块自动生成的反汇编描述语言,为IDA处理器模块插件的扩充提供支持.该描述语言采用基于上下文无关文法的属性文法表现形式,包括对处理器存储系统的声明以及对处理器指令集的语法和语义描述.应用结果表明,该方法适用于IDA处理器模块插件的扩充.%Aiming at the problem that IDA can not provide supports of disassembling for all kinds of processor module at present, this paper proposes a way of establishing a formalized description language to back for the extension of IDA processor module plug-in. The description language uses the context-free grammar and the attribute grammar, including the declaration of the memory system and the syntax and semantic description of the processor instruction set. Application result shows that this method suits for the extension of IDA processor module plug-in.
