执行下列指令后: MOV AX, 1234H MOV CL, 4 ROL AX, CL DEC AX MOV CX, 4 MUL CX HLT寄存器AH的值是( )。
A: 92H
B: 8CH
C: 8DH
D: 00H
A: 92H
B: 8CH
C: 8DH
D: 00H
举一反三
- 执行下列指令后,(AX)=( )。 MOV AX,1234H MOV CL,4 ROL AX,CL DEC AX MOV CX,4 MUL CX HLT
- 执行完下列指令后: MOV AX,1234H MOV CL,4 ROL AX, CL DEC AX MOV CX,4 MUL CX HLT (AL)= ( )。 A: 60H B: 00H C: 04H D: A0H
- 写出下列程序段执行后AX的值为多少? MOV AX, 1234H; AX=(1)H MOV CL, 4 AND AL, 0FH; AX= (2) H ADD AL, 30H; AX= (3)H SHL AH, CL; AX= (4)H AND AH, 0F3H; AX= (5)H
- 执行下列指令后:MOV MOV ROL DEC MOV MULHLT AX, 1234H CL, 4 AX, CL AXCX, 4CX寄存器AL的值是[input=type:blank,size:1][/input]
- 写出每条汇编指令执行后相关寄存器的值 mov ax,62627 AX=________________ mov ah,31H AX=________________ mov al,23H AX=________________ add ax,ax AX=________________ mov bx,826CH BX=________________ mov cx,ax CX=________________ mov ax,bx AX=________________ add ax,bx AX=________________ mov al,bh AX=________________ mov ah,bl AX=________________ add ah,ah AX=________________ add al,6 AX=________________ add al,al AX=________________ mov ax,cx AX=________________
