1、学号：221000116计算机组成原理与汇编语言程序设计实验报告姓名：郭海南计算机组成原理与汇编语言程序设计实验报告实验一实验内容：查看CPU和内存，用机器指令和汇编指令编程。实验任务：（1）了解并熟悉WINDOW中DEBUG工具.DEBUG的命令及功能如下:*r【register】命令用于查看、改变寄存器的内容；rr ax*d【不懂为什么叫D】查看内存的内容；d 段地址:偏移地址，段地址可以用CS,DS,SS,ES代替*e 【edit】改写内存的内容e 段地址:偏移地址依次填入要赋值的数字，每个字节检用空格间隔开*a 【asm，嘿嘿，我自己猜的，】以汇编的形式向内存写入东西a 段地址:偏移

2、地址如果没有指定，一开始是CS:IP，其他的时上一次修改的末尾。*u 【英文不好，不懂，估计是un-ooxx反汇编吧】将内存中的机器码以汇编指令显示出来格式和a命令一样*t 【真不懂】执行CS:IP指向的命令（2）用A、E命令向2000:0内存中写入以下命令，并执行mov ax,1add ax,axjmp 2000:0003计算机组成原理与汇编语言程序设计实验报告实验二实验内容：用机器指令和汇编指令编程实验任务：（1）预备知识:了解DEBUG是如何执行D命令的在E,A,U命令中使用段寄存器 mov ss,ax mov sp,100（2）使用DEBUG执行一段程序-a13B4:0100 mov
