The JAE instruction jumps if the (unsigned) first operand is greater than or equ

Question

The JAE instruction jumps if the (unsigned) first operand is greater than or equal in magnitude to the (unsigned) second operand. True False Show the values of the Carry, Zero, and Sign flags after the cmp instruction shown below has been executed by the CPU. Your answer should be a 1 or 0 for each flag. mov alpha,00000101b cmp alpha,00000111b: CF - ? ZF - ? SF-? CF = ZF = SF = The JB instruction has exactly the same effect as the JNA instruction. True False Show the values of the Carry. Zero, and sign flags after the cmp instruction shown below has been executed by the CPU. Your answer should be a 1 or 0 for each flag. mov al,00000110b cmp al,00000101b: CF = ? ZF = ? SF =? CF = ZF = SF =

Explanation / Answer

7)

True ;

Explanation :

JAE stands for jump above or equal ; control will jump only when first operand is more or equal to the magnitude of the second operand

8)

al=0x00000101b

cmp al,0x00000111b => al - 0x00000111b

CF = 1 (as borrow is generated)

ZF = 0 (virtual result is not zero)

SF = 1 (virtual result is negative)

9)

False

Explanation:-

Not JNA and JB are not exactly same.As, JNA stands for jump only if not above i.e if the two operands are equal then also it will jump but whereas in case of JB ,control will only jump when the first operand is less than the second operand

10)

al=0x00000110b

cmp al,0x00000101b => al - 0x00000101b

CF = 0 (as no carry or borrow is generated)

ZF = 0 (virtual result is not zero)

SF = 0 (virtual result is positive)
