SUB R4,R1,R2
R4 = 1011 1001 0101 1110 1111 0001 1011 0111

LOGICAL :-
Given :-

R1 = 0100 0110 1010 0001 1111 0001 1011 0111
R2 = 1111 1111 1111 1111 0000 0000 0000 0000

AND R3,R1,R2
R3 = 0100 0110 1010 0001 0000 0000 000 0000

ORR R4,R1,R2
R4 = 1111 1111 1111 1111 1111 0001 1011 0111

EOR R5,R1,R2
R5 = 1011 1001 0101 1110 1111 0001 1011 0111

MVN R7,R2
R7 = 0000 0000 0000 0000 1111 1111 1111 1111

Shift :-

Given :-
R5 = 1111 1111 0001 1100 0001 0000 1110 0111
