Abstract:

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.

Key words: Algorithm, Disassembling
