东北大学软件学院汇编实验报告3.docx

1、东北大学软件学院汇编实验报告3(附录二)汇编语言程序设计实验报告 实验名称循环结构与子程序设计实验班 级学 号姓 名日 期成 绩评 阅 人 软件学院一、 实验目的与意义了解和掌握加、减、乘、除指令的在程序设计中的用法和应注意的问题，了解和掌握移位指令的功能、作用和方法。了解和掌握循环控制类指令的功能、作用和方法。学会循环程序设计的方法。学习汇编语言输出输入语句的设计。二、 实验环境操作系统：windows7调试软件名称及版本号：Microsoft Visual Studio2008三、 实验的预习内容预习的主要内容：预习了加减乘除指令，移位指令，循环指令的作用及方法，学习力函数的调用，在屏幕上

2、打出指定字符和数字实验思路：将寄存器赋值，然后对寄存器进行加减乘除，移位的运算，观察寄存器的数值变化，用逐语句观察循环语句中程序执行的顺序，了解循环的作用四、 实验的步骤与调试方法实验的大致步骤：在.code中对程序进行加减乘除，移位操作，观察寄存器的变化实验中遇到的问题及调试方法：在做9*9乘法表时，由于是32位的操作系统，无法用中断来进行回车换行，最后通过给赋值，直接打出回车五 实验数据与实验结果（1） 在DEBUG系统状态下，分别编制、调试并记录以下加、减程序段的每一条指令的运行情况，查看寄存器的结果：（）MOV EAX,2389 EAX = 00000955 EBX = 7FFDF00
