1. The combinational circuit shown on the right performs arithmetic operations on three 4-bit integers, A, B, and C based on the values of inputs x and y, as explained in the table below. We ignore carry, borrow, and overflow for this circuit. xy Operation 00 Z= A + B 01 Z=2A 10 Z=B-C 11 Z A-C X A B C £₁ £₁ 4 Z Design this circuit using only a single parallel adder, two 4-bit 2:1 MUXs, and NOT gates. Use the fewest possible number of gates and multiplexers to make your circuit design as simple as possible. (Note: A 4-bit 2:1 MUX has two inputs, each having a size of 4 bits.)
