程序反汇编的一种方法

本文以Z80机为例，给出了一种反汇编目标代码的算法。借助于加权有向图这一数学工具，将机器代码的反汇编问题转化成有向图的遍历问题，可很快地反汇编出目的码的符号指令码及数据区代码，大大地提高工作效率。该算法在本文中虽是以Z80机为例给出，但不难推广到其它机种。

AN ALGORITHM FOR Z-80 DISASSEMBLING

Taking Z-80 for example，this paper presents an algorithm which disassembles the object codes into mnemonics. By means of the graph, the issue of disassembling object code is transformed weighted-direct into travelling weighted-directed graph. Therefore，the instruction mnemonics and data area codes can be obtained easily and quickly, making the process of disassembling much shortened, Although the algorithm is developed for Z-80 machine in the paper, it is not difficult to extend it to other machine instructions.
