3.a. i. Use strength reduction to create a circuit that computes P-46"Q 12 using only shifts and adds. P is an n-bit output and Q is a 12-bit input. Show how many bits wide P must be. ii. Estimate the transistors in the circuit and compare to the 12 estimated transistors in a circuit using a multiplier. Assume the output of each shifter is 12 bits. However, when 2 numbers are summed remember to add one bit of width to prevent overflow. in 12 ii. If each shifter is a barrel shifter with the configuration shown, sh in what will the controls be for each shifter in the configuration of part a.i.? 12 Qshifte bi. Use strength reduction to create a circuit that approximately computes P = (1/7)"Q using only shifters and adders. Strive for accuracy to the thousandths place (0.143). P is a 12-bit output and Q is a 12-bit input. Use wider internal components and wires as necessary to prevent internal overflow ii. Design a barrel shifter large enough to handle all the shifts required for the operation in part b.i. What will be the controls for each shift? 3.a. i.
