汇编语言 关于寻址方式
已知(DS)=1000H,(SI)=0200H,(BX)=0100H,(10100H)=11H,(10101H)=22H,(10600H)=33H,(10601H)=44...
已知(DS)= 1000H,(SI)= 0200H,(BX)= 0100H,(10100H)= 11H,(10101H)= 22H,
(10600H)= 33H,(10601H)= 44H,(10300H)= 55H,(10301H)= 66H,(10302H)= 77H,(10303H)= 88H,试分析下列各条指令执行完后AX寄存器的内容。
(1)MOV AX,2500H (AX)=2500H
(2)MOV AX,500H[BX] (AX)==4433H
(3)MOV AX,[300H] (AX)=6655H
(4)MOV AX,[BX] (AX)=2211H
(5)MOV AX,[BX][SI] (AX)=6655H
(6)MOV AX,[BX+SI+2] (AX)=8877H
请问大神 这道题 第二小题 AX=10600H (33H) 为什么答案写的是4433H 而不是3344H
第六小题的MOV AX,[BX+SI+2] 这个东西的AX要怎么去计算 展开
