2.Condition move when ZF=0 or CF=1 and it is available only in 8086 microprocessor.

3.Condition move when ZF=1 or CF=1 and it is available only Pentium Pro-Core2

4.Condition move when ZF=1 or CF=0 and it is available only in 8086 microprocessor.

The instruction INSD is?

1.Transfers a two bytes of data from an I/O device into the extra segment memory location 2.addressed by the DI register. The I/O address is contained in the DX register.

3.Transfers a two words of data from an I/O device into the extra segment memory location 4.addressed by the DI register. The I/O address is contained in the DX register.

5.Transfers a byte of data from an I/O device into the extra segment memory location 6.addressed by the DI register. The I/O address is contained in the DX register.

7.Transfers a two words of data from an I/O device into the extra segment memory location 8.addressed by the DI register. The I/O address is contained in the AX register.

XLAT perform the following?

1.Load AL register with content of memory location specified by DS:[AL+BX]

2.Load AL register with content of memory location specified by DS:DI

3.Load AL register with content of memory location specified by DS:SI

4.Store the content of AL register into memory location specified by DS:[AL+BX]

if AX=802F H what would be the content of EBX after execution of MOVZX EBX, AX

FFFF802F H

802F802F H

F000802F H

0000802F H

f AX=0EC8 H and BX=D205, what would be the contents of AX and BX after execution of the instruction XCHG AX, BX

Both AX and BX are D205 H

Bothe AX and BX are 0EC8 H

AX=05D2 H and BX=C80E H

AX=D205 H and BX=0EC8

let AX=055B H and memory location (DS:DI = 1000:0010) is contents EC2F H, after execution of the instruction MOV AX, [DI]. what would be the content of AX.

AX=EC2F H

Still AX=055B H

AX= 10010 H

None of them

What would be the content of AL after execution the instruction MOV Al, -1 H

7F H

1001H

None of them

-1 H

what

would be the content of AX after execution the instruction MOV AX, 18 MOD 7

0004 H

None of them

0025 H

0002 H

?The instruction COMVG is Condition move when ZF=1 and SF=1 Condition move when ZF=1 or SF=0 Condition move when ZF=0 and SF=1 Condition move when ZF=1 and SF=0 O ?The execution of the sequences PUSH AX PUSH BX POP BX POP AX are perform Exchange the contents of AX and BX Both AX and BX have the same contents Do nothing None of them O
