附：8086CPU 寄存器英文全称
1、通用寄存器
AX（accumulator）、BX（base）、CX（count）、DX（data）这些寄存器可以字（16 位）或字节（8 位）单位形式访问；
SP（stack pointer）、BP（base pointer）、SI（source index）、DI（destination index），这些寄存器只能以字（16 位）单位形式访问。
2、专用寄存器
IP（instruction pointer）、SP（stack pointer）；;
FLAGS 又称 PSW(program status word) 分为：
① 条件码
OF（overflow）、SF（sign）、ZF（zero）、CF（carry）、AF（auxiliary）、PF（parity）
② 控制标志
DF（direction）
③ 系统标志位
TF（trap）、IF（interrupt）、IOPL（I/O privilege level）
3、段寄存器
CS（code）、DS（data）、SS（stack）、ES（extra）
