Abstract: Compiler is an important part of embedded system software, it has great impact on software development of embedded system. This paper analyzed the structure of an compiler automatic generation tool genmd, based on the idea of combining ADL with retargetable compilers, and put emphasis on abstracting and modeling of instruction recognition and machine description generation. Meanwhile, a method was provided and implemented to solve the limitation of genmd that was unable to support instructions of branch and jump.

Key words: compiler, ADL(Architecture Description Language), automatic generation, genmd, embedded system
