(简答题)
设有关寄存器及存储单元的内容为:DS=2000H,BX=0100H,AX=1200H,SI=0002H,[20100H]=12H,[20101H]=34H,[20102H]=56H,[20103H]=78H,[21200H]=2AH,[21201H]=4CH,[21202H]=0B7H,[21203H]=65H,若MOV BX,[1200H]指令单独执行后,BX为多少?
(简答题)
现有(DS)=2000H,(BX)=0100H,(SI)=0002H,(20100H)=12H,(20101H)=34H,(20102H)=56H,(20103H)=78H,(21200H)=2AH,(21201H)=4CH,(21202H)=0B7H,(21203H)=65H,说明下列指令执行后AX寄存器的内容。 (1)MOVAX,1200H (2)MOVAX,BX (3)MOVAX,[1200H] (4)MOVAX,[BX] (5)MOVAX,1100H[BX] (6)MOVAX,[BX][SI] (7)MOVAX,1100H[BX][SI]
(简答题)
给定寄存器及存储单元的内容为:(DS)=2000H,(BX)=0100H,(SI)=0002H,(20100)=32H,(20101)=51H,(20102)=26H,(20103)=83H,(21200)=1AH,(21201)=B6H,(21202)=D1H,(21203)=29H。试说明下列各条指令执行完后,AX寄存器中保存的内容是什么。 (1)MOVAX,1200H (2)MOVAX,BX (3)MOVAX,[1200H] (4)MOVAX,[BX] (5)MOVAX,1100H[BX] (6)MOVAX,[BX][SI]
(简答题)
现有(DS)=2000H,(BX)=0100H,(SI)=0002H,(20100H)=12H,(20101H)=34H,(20102H)=56H,(20103H)=78H,(21200H)=2AH,(21201H)=4CH,(21202H)=B7H,(21203H)=65H,试说明下列各条指令执行完后AX寄存器的内容。MOV AX,[1200H]。
