4 Design 1 Bit Alu Four Operations Add Sub 5 Points Give Gate Level Design Circuit Use Log Q37105557

4. Design a 1-bit ALU that has four operations: AND ADD ·SUB a) (5 points) Give the gate-level design of this circuit. Use only logic gates, adder, a 4:1 MUX and a 2:1 MUX. For full credit the SUB operation must use the same adder as the ADD operation. (b) (3 points) Give the truth table for your ALU. Use the following table and include all control lines.
