3. Note that in the class we studied only A + B, and A – B. We used a mode bit M to control if the circuit should compute A+B or A-B. Here, we have three operations, which means 2 mode bits M1 Mo are required to control the operation of the circuit. B: B1 Bo B3 M A: AI Ao Cout Cia Cout Cin Cout Cin Cout Cin Full Adder Full Adder Full Full Adder Adder So This circuit shows the Mode bit M, and two handles two operations, A + B, and A- B. You are required to modify this circuit such that it can handle three operations, A+B, A-B, B-A. You would need two mode bits to handle three operations.
