The combinational circuit shown below 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 on the left. We ignore carry, borrow, and overflow for this circuit. xy 00 01 10 11 operations Z = 2C Z=A+C Z=C-B Z = A - B A 4 B C 1414 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.)
