Webax=0000H bx=0000H 8086 16位 一个寄存器能存储16个2进制数 例如:al和ah没有关系,当ah的值超出8位时,CPU就会丢弃数据,当al的值超出8位时,CPU不会丢弃数据 但不会进位到ah寄存器中 汇编指令进行操作时,要注意双方位数和数据大小溢出问题 检测点2.1详解: Web#LOAD_SEGMENT=FFFFh# #LOAD_OFFSET=0000h# #CS=0000h# #IP=0000h# #DS=0000h# #ES=0000h# #SS=0000h# #SP=FFFEh# #AX=0000h# #BX=0000h# #CX=0000h# #DX=0000h# #SI=0000h# #DI=0000h# #BP=0000h# jmp st1 nop dw 0000 dw 0000 dw ad_isr dw 0000 db 1012 dup(0) st1: cli mov ax,0200h mov ds,ax ... Web8086cpu寄存器都是16位的,一共14个,分别是ax,bx,cx,dx,si,di,sp,bp,ip,cs,ss,ds,es,psw。 其中 AX,BX,CX,DX 四个寄存器通常存放一般性的数据,称为 通用寄存器 。 而且为了兼容上一代的8位寄存器,这四个寄存器 可以拆开成两个8位的寄存器 来使用。 binary to bcd
