Question 4 [24 Points]-Register Design a 3-bit shift register with 2 control inputs C1 and CO, using three edge-triggered D rlip-flops and three 4 X 1 multiplexers. Data outputs are Qr, Qs,Qo. The register operates according to the following function table: C1 0 0 CO Functiorn 0 Rotate 1-bit leftward (down) (Q0 towards Q2, Q2 to Q0) 1's Complement the register contents Set register bits to zero 0 1 Rotate 1-bit rightward (up) (02 towards 00, 00 to 02 1 Complete the connections among the blocks and control signals to achieve the shift register operation as described above. For simplicity, the clock signal is not shown in this block diagram (and you do not have to show it). It would be ok to show the connectivity by naming the wires to each MUX inputs. Label the input of each mux clearly 0 4x1 1 MUX Q1 1 MUX 3 S1 So 02 0 4x1
