Design an 8-bit shifter that shifts its inputs two bits to the right (shifting in 0s) when the shifter's shift control input is 1(refer to slide 58 for more information).
The figure given below is a 4-bit right shifter implemented with four 2 to 1 muxes. When sh = ‘1’ shift to right by 1 position ( >> ) is performed. If sh = ‘0’ no shift. You can use this figure to implement the 8 –bit shifter. You must extend it to 8 –bit and adjust wirings for shift by 2 positions when sh = ‘1’.
