+# 一、实验目的
+
+1. 进一步学习汇编语言基本指令使用方法；
+2. 学习DEBUG调试工具的基本使用方法；掌握debug调试命令a、u、r、d、t、g等；
+3. 逐条观察程序指令的执行过程，理解指令的功能，理解程序自动、顺序地执行的概念，实践其过程(重点)。
+
+# 二、实验内容
+
+1. 编写、输入一个32位二进制数相加程序，逐条执行指令，观察指令执行情况。
+1. 使用已经过汇编和连接的小程序(t3-2.exe)，将其装入内存，逐条执行指令，观察执行过程和结果。在实验过程中，使用E命令修改XXX和YYY单元中的数据，再重新计算其结果。

+# 五、实验总结
+
+ 熟练掌握了各种指令以及调试步骤，收获颇丰。
+
+# 六、思考题
+
+> 程序中的指令、数据是如何在存储器中存储的？
+
+分别在不同的段中按顺序存储
+
+> 如何理解程序执行过程的顺序性？
+
+程序按指令在代码段内存储的顺序执行。如需人为改变执行顺序，可以指定ip为要执行的指令的地址。
+
+> 如何理解标志位寄存器中的数据？
+
+ 标志寄存器在CPU内部，用于存储算术逻辑运算后的结果特征和控制CPU的工作方式或工作状态。

+# 一、实验目的
+
+1. 了解汇编语言子程序的概念。
+2. 掌握汇编语言子程序的定义、调用和返回。
+3. 掌握设计汇编语言子程序及过程的基本方法。
+4. 清楚调用指令CALL及返回指令RET执行时堆栈内容及指针的变化。
+5. 掌握子程序和主程序间的参数传递方法。
+
+# 二、实验内容
+
+试编写一个有主程序和子程序结构的程序模块。
+
+主程序：要求从键盘接收一串字符并存于字节数组TABLE中，显示字符CHAR出现的次数。
+
+子程序：在以TABLE为首地址的字节数组中查找CHAR，统计出现的次数。
+
+# 三、流程图
+
+![graph](graph.drawio.svg)
+
+# 四、实验过程与分析
+
+![1](1.png)
+
+将源代码放入MASM路径下，编译。
+
+没有警告和报错。
+
+![2](2.png)
+
+LINK链接程序。
+
+![3](3.png)
+
+出现提示信息。
+
+![4](4.png)
+
+输入字符串，按下回车。
+
+程序打印出指定字符“**A**”出现的次数。
+
+# 五、实验总结
+
+在本实验中，我了解了汇编语言子程序的概念，掌握了汇编语言子程序的定义、调用和返回，以及设计汇编语言子程序及过程的基本方法。
+
+# 六、思考题
+
+> 子程序和主程序之间的参数传递是通过什么方式实现的？
+
+通常情况下，主、子程序之间传递参数可以通过以下四种方式实现：
+
+1. 寄存器传送参数
+2. 存储单元传送参数
+3. 堆栈传送参数或参数地址
+4. 多模块之间的参数传递
+
+**本实验程序使用寄存器传递参数。**
+
+> 在DEBUG环境下观察执行CALL指令时CS、IP寄存器是否变化。
+
+![5](5.png)
+
+执行CALL指令的时候
+
+- 如果是段内近调用，不会改变CS，但是IP会改变。（本实验程序是这种情况，如图所示可见CS不变，IP变）
+- 如果是远调用，CS和IP都会改变。
+
+> 在DEBUG环境下观察执行CALL、RET时堆栈的变化。
+
+![6](6.png)
+
+![7](7.png)
+
+由执行CALL前后SP值的变化和对应地址记录的值，可知由于是近调用，将IP压入栈中记录，SP记录了要返回的IP=0017H。
+
+（由于DEBUG环境无法输入字符串，很难观测RET指令执行时的情况。实际上RET时，SP会回退，原来CS和IP的值会退栈，然后赋值给当前的CS和IP。）

+<h1><center><strong>实验二 利用8255A实现LED的流水点亮实验</strong></center></h1>
+
+### 一、实验目的
+
+该实验的目的在于掌握8255A和微机接口的连接方法，了解8255A的基本的工作原理和编程方法。
+
+### 二、实验内容
+
+**任务一：**PA口接8个拨动开关K1-K8，PB口接8个LED。初始由开关K1-K8设定8位不同的值，当执行程序后LED按K1-K8初始设定的值点亮，并向右流动（8255A工作在0方式）。
+
+**任务二：**在数码管上显示“8255-A”。
+
+### 三、流程图
+
+**任务一：**
+
+![task1.drawio](task1.drawio.svg)
+
+**任务二：**
+
+![task2.drawio](task2.drawio.svg)
+
+### 四、实验过程与分析
+
+**任务一：**
+
+首先在实验箱中将接线连好。将8255A芯片的CS连到280H地址。因此命令口为283H，PA口为280H，PB口为281H，PC口为282H。
+
+将PA口连到开关上，PB口连到LED灯上。
+
+然后设置好开关。将代码编译后运行。运行效果如视频所示。
+
+**任务二：**
+
+首先在实验箱中将接线连好。将8255A芯片的CS连到280H地址。将PA口连到位码接口上，PB口连到段码接口上。
+
+<img src="task2.jpg" alt="task2" style="zoom:25%;" />
+
+将代码编译后运行。运行效果如图所示。
+
+### 五、实验总结
+
+在本实验中，我掌握了8255A和微机接口的连接方法，了解了8255A的基本的工作原理和编程方法，收获颇丰。
+
+### 六、思考题
+
+> 在本实验的硬件电路中，能使用C口对LED指示灯控制码？如果可以写出2种控制方法（编程方法）。
+
+**控制方法一：**使用命令口直接将PC口置位。
+
+```assembly
+MOV    DX, 283H            ; 设置命令口
+MOV    AL, 00000101B       ; 0|xxx|010(指定PC2引脚)|1(置位)
+OUT    DX, AL              ; 输出
+```
+
+**控制方法二：**使用方式0，将PC口置为数据输出口。
+
+```assembly
+MOV    DX, 283H
+MOV    AL, 10000000B       ; 1|00(A组0方式)|0(PA输入)|0(PC4-7输出)|0(B组0方式)|0(PB输出)|0(PC0-3输出)
+OUT    DX, AL
+
+MOV    DX, 282H
+MOV    AL, 00000001B       ; PC1为高电平
+OUT    DX, AL
+```
