2020年汇编实验报告

实验三算术运算与代码转换程序设计一、实验目的1）掌握算术运算程序的设计方法。

2）掌握代码转换程序的设计方法。

3）进一步掌握各种程序结构。

4）熟练掌握和使用用DEBUG调试程序。

二、实验内容1）编制两个多字节整数加法和减法程序，并将结果按十六进制形式显示在屏幕上。

2）编制程序实现二进制定点数与十进制数的ASCII码串之间转换，并将结果显示在屏幕上。

3）编写程序计算从键盘输入两个不超过四位的十进制数的和、差、积、商，并以十进制形式输出。

4）写程序把从键盘输入的四位十六进制数转换为压缩的BCD码，并显示输出。

5）编写一通用过程用来将十进制数(从键盘输入)转换为P(从键盘输入)进制数。

三、实验设备PC机一台四、实验步骤1) 按程序流程图编制实验程序。

2) 输入源程序。

3) 汇编、连接程序，执行程序，检查结果。

4) 程序的执行可用DEBUG的G命令,也可用T命令单步跟踪执行。

5) 用D命令检查执行结果。
