An ALU of a processor uses the shift register shown in Figure P7.1 to perform shift and rotate operations. Inputs to the control logic for this register consist of

All shift and load operations are controlled by one clock input. The shift register is implemented with edge-triggered D flip-flops. Give a complete logic diagram for the control logic and for bits 70, 71, and 15 of the shift register.LO1
