# CPU架构
## 总线接口单元
实现指令的读取功能
实现数据的读取写入功能
### 数据总线
字节编址:`1Byte = 8Bit`
总线编码: 20Bit，支持1MB的存储大小
寄存器：16Bit，仅能描述64KB大小
基寄存器 * 16 + 偏移寄存器 = 总线地址
### 段寄存器
1MB的空间分段，每段大小不超过64KB，段地址即16位寄存器地址 * 16
程序多次运行，变化的是段寄存器，逻辑地址保持不变
段之间可以分开也可以重合，取决于数据如何存储
- CS
- 存放指令的代码段地址
- DS
- 存放数据的数据段地址
- SS
- 程序堆栈段地址
- ES
- 附加段寄存器
- IP
- 专用寄存器，指令偏移地址
- 仅由跳转类指令间接控制
- 内部寄存器
### 指令队列
六字节，先进先出，跳转时刷新整个队列
## 执行单元
对指令进行译码，并执行
### 通用寄存器
寄存器描述的地址都是偏移地址，每次运行的偏移地址保持不变
- AH + AL = AX
- 累加器
- BH + BL = BX
- 基址寄存器
- CH + CL = CX
- 计数器
- DH + DL = DX
- 数据寄存器
- SP
- 堆栈指针寄存器
- 会受到指令控制，不应用于其他目的
- BP
- 基址指针寄存器
- SI
- 源变址寄存器
- 如字符串首地址
- DI
- 目的变址寄存器
- 如字符串第n个元素地址
# 程序数据
```assembly
assume cs:code, ds:data, ss:stack ;定义了三个段 code,data,stack 只是为了阅读的方便，用其他的名称是一样的。
data segment
dw 0123h, 0456h, 0789h, 0abch, 0defh, 0fedh, 0cbah, 0987h
data ends
stack segment
dw 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
stack ends
code segment
start: mov ax,stack # stack 段的首地址
mov ss,ax
mov sp, 20h;
mov ax, data ;
mov ds, ax; ds指向data 段的首地址
mov bx,0
mov cx, 8
s: push [bx]
add bx, 2
loop s ;以上将data段中的0~15单元中的8个字型 数据一次入栈
mov bx,0
mov cx,8
s0: pop [bx]
add bx,2
loop s0; 出栈，把数据放回到data段。 如此就把数据逆序了。
mov ax, 4c00h
int 21h ;中断调用操作系统子程序
code ends
end start
```
## 代码段
代码数据
## 数据段
程序数据
## 堆栈段
### 标志寄存器
ALU计算标志，中断、出错等
状态标志
- 进位标志CF
- 奇偶标志PF
- 调整标志AF
- 零标志ZF
- 符号标志SF
- 溢出标志OF
控制标志
- 方向标志DF
- 中断标志IF
- 单步标志TF
### ALU
算术逻辑单元，核心计算单元，电路实现了基础运算的程序功能
# 指令实例
## 接口
```assembly
mov dest,src ;dest ← src
mov al,[bx+si+6] ;指令功能：AL←[BX+SI+6]
;[取地址存储的数据]
```
## 函数调用
```assembly
;lea 取函数地址到rax寄存器
lea rax,[TPoint::`vcall'{0}' (07FF6C97EC00Eh)]
