假设8086/8088微处理器的(SS)=1050H,(SP)=0008H,(AX)=1234H。执行PUSH AX指令后,下面哪一个选项是正确的执行结果( )。
A: (10508H)=12H,(10507H)=34H
B: (10508H)=34H,(10507H)=12H
C: (10507H)=12H,(10506H)=34H
D: (10507H)=34H,(10506H)=12H
A: (10508H)=12H,(10507H)=34H
B: (10508H)=34H,(10507H)=12H
C: (10507H)=12H,(10506H)=34H
D: (10507H)=34H,(10506H)=12H
举一反三
- 假设8086/8088微处理器的(SS)=1050H,(SP)=0008H,(AX)=1234H。执行PUSH AX指令后,下面哪一个选项是正确的执行结果( )。 A: (10508H)=12H,(10507H)=34H B: (10508H)=34H,(10507H)=12H C: (10507H)=12H,(10506H)=34H D: (10507H)=34H,(10506H)=12H
- 如果(A)=34H,(R7)=0ABH,执行XCH A, R7;结果(A)=_________H,(R7)=________H
- 设堆栈指针SP的初值为2000H,AX=3000H,BX=5000H,试问:(1)执行指令PUSH AX后SP= H(2)再执行PUSH BX及POP AX后,SP= H,AX= H(3)最后执行POP BX后,SP= H,BX= H
- 水淹车按水淹时间分,第三级为()。 A: 4h<H≤12h B: 24h<H≤48 C: 12h<H≤24 D: 3h<H≤5h
- 如果(A)=45H,(R1)=20H,(20H)=12H,执行XCHD A, @ R1后,结果(A)= ______ H,(20H)= ______ H。
