Q$3$ ALU

Given the arithmetic circuit, logic circuit, and ALU diagram for LSB $($A$0,$ Bo$)$ of two $2-$bits inputs

$($A$,$ B$),$ fill in the Operation Select and $S_0)$ and Carry$-$in $C_0$ for each operation of output

$F$ in the table below.

Note that:

Both A and B are represented in signed $2\text{'}$s complement form.

$S_1$ is a higher bit than $S0.$

The arithmetic and logic circuits for MSB $(A_1,B_1)$ are the same as the ones for LSB$.$

All circuits for MSB and LSB share S$2,$ S$1,$ and So$.$

If any input is "don't care," mark $"$d$."$
