In order to analyse their software systems, the fundamental methods of disassembling are discussed, i. e. the direct generating method and the table look-up transform method, and pro-posed the concept of basic code about the instruction object code. 为分析Z280MPU系统软件,本文论述了反汇编的基本方法&直接生成法和查表转换法,给出了指令目标代码基本码的概念。
In this thesis, MCU table look-up and interpolate instruction was employed in a new fast integer evolution algorithm that has high precision. 特别是本文应用查表和插值指令实现了高精度快速整数开方的新型算法,在装置中得到了应用,效果很好。
