实验一ARM汇编指令

1.实验目的

(1)初步学会使用ADS1.2集成开发环境及ARM软件模拟器；

(2)通过实验掌握简单ARM汇编指令的使用

2.实验设备

(1)硬件：PC机

(2)软件：ADS1.2集成开发环境，Windows98/2000/NT/XP

3.实验内容

(1)熟悉ADS开发环境，并使用LDR/STR和MOV等指令访问寄存器或

存储单元；

(2)使用ADD/SUB/LSL/LSR/AND/ORR/等指令完成基本数学逻辑运算。

1)实验A——完成运算x+y,把结果存入堆栈寄存器(R13)中

在该实验中主要是通过MOV/STR/LDR/ADD等指令来完成基本的加操作运

算。

2)实验A运行截图
