The 8 bit-registers R0, R1, R2, R3 and R4 initially have the following hexadecimal values;
R0=D4
R1=72
R2=D3
R3=CF
The left-most bit is used as a sign bit where negative numbers are represented in 2’s complement. Determine the 8 bit binary values for R0, R1, R2, and R3 after executing the following microoperations.
A. R0 < shr R0
B. R1 < shl R1
C. R2 < ashr R2
D. R3 < ashl R3
Where shl means shift left, shr = shift right, ashl = arithmetic shift le.
