00_汇编缩写大全

常见汇编命令英文缩写

寄存器类（register）：

通用寄存器:AX,BX,CX,DX。

段寄存器：代码段寄存器CS--code segment , 数据段寄存器DS--data segment , 堆栈段寄存器SS--stack segment，附加段寄存器ES--extra segment。

特殊功能寄存器：指令指针寄存器IP--instruction pointer ，堆栈指针SP--stack pointer ，基址指针BP--base pointer，源变址寄存器SI--source index，目标变址寄存器DI--destination index，标志寄存器FR--flag register（或者叫程序状态字PSW--program status word）。

PSW常用的标志有：

标志                             值为1时的标记               值为0时的标记

OF(overflow flag)         OV(overflow)                  NV(not overflow)

ZF(zero flag)              ZR(zero)                       NZ(not zero)

PF(parity flag)            PE(parity even)               PO(parity odd)

CF(carry flag)              CY(carried)                   NC(not carried)

DF(direction flag)         DN(down)                      UP(up)   

SF(sign flag)              NG(negtive)                   PL(plus)

TF(trap flag)

IF(interrupt flag)

AF(auxiliary flag)
