Interview Question

Draw the circuit diagram for barrel-shifter that can shift 3 bits in either direction. The shifter should take 3 bits as selectors: one bit is a selector, one bit indicates whether the shift is in the positive (value of 1) or negative (value of 0) direction, one bit indicates whether the shift is a distance of 1 (value of 0) or 2 (value of 1). You may use multiplexers in your design without drawing the inner workings of the multiplexer.
