Jesign a 4-bit, 8-function Arithmetic Unit that meets the following specifications: Fints: - Inputs S2-S0 select what operation is being performed by the circuit. - A is a 4-bit number and B is a 4-bit number. - Use 4-to-1 MUXs and one 4-bit adder in your design. - From the table, we can see that the first operand of the addition is always A; the second and third operands of the addition vary based on the operation selected (S2-S0). Third operand is either 0 or 1 .
