Rewrite the following instructions such that each of them is

Rewrite the following instructions such that each of them is conditionally executed according to the given flag(s) setting.

Solution

Solution:

instruction	flags	conditional instruction
ADD R1,R2,R3	C=1&Z=0	if Cflag is set to R1=R2+R3 and not equal
RSB R2,R3,R4	Z=0&N=V	Not equal R2,R3,R4 and R4>=R2,R3
MOV R0,R1	V=1	R0=R1, overflow
