Need help ASAPin computer architecture. Thumbs up to correct answer!

Design and implement a 4-bit ALU for following micro operations. You can draw your circuit in A3 size paper.

S3 S2 |S1| SO Cin Operation A+1 A+B A+B+1 A+B' A+B'+1 A-1 AAB 0 1 0 X 0 1 0X 0 1 X 1 0 X XX AB SHR SHL In this design A and B are two 4-bit binary inputs, s0, sl, s2, s3 and Cin are control signals. There is no need to draw the internal circuits of MUX & Full adders. You should make clear all connections from input to the outputs S3 S2 |S1| SO Cin Operation A+1 A+B A+B+1 A+B' A+B'+1 A-1 AAB 0 1 0 X 0 1 0X 0 1 X 1 0 X XX AB SHR SHL In this design A and B are two 4-bit binary inputs, s0, sl, s2, s3 and Cin are control signals.
