Explanation / Answer

HI please go threw the solution.

5)

0xAC 1010 1100

+0x92 1001 0010

ans- 0x13E 10011 1110

CF = 1, SF = 0, OF = 1 ZF =0

6)

0x3D

+(- 0x3D)

ans 0x00

so ,

2's compliment of 0x3D

0011 1101

-> 1100 0010

-> 1100 0011

so, now add these two numbers

0011 1101

1100 0011

ans- 10000 0000

so, ZF =0

7)

a) 0x8F SAR::hex:0x08 decimal = 8

befor -> 1000 1111

0010 0011

after -> 0000 1000

b) 0xFB SAR::hex=0x0F decimal = 15

befor -> 1111 1011

0011 1110

after -> 0000 1111
