摘要
本文分析了MCS—51指令系统的结构、特点和直接寻址空间的组成,介绍了反汇编程序设计方法和反汇编打印接口。反汇编打印模块能在开发机上任何2K程序存储器地址空间工作,把MCS—51指令机器码生成汇编语言并按其标准格式打印出来,也可打印机器码清单或数据,适用于各种通用打印机,并具有自动换页功能。
A Procedure for the design of MCS—51 disassembler print module and its print interface is introduced. The said print module can work in the address space of any 2K program storage on a development system,and can generate assemblers from MCS—51 instruction machine code and print them in their standard format. The print module can also print the machine code inventory or data. The module is adaptable to various general purpose printers and capable of form advance.
