Unformatted text preview: Shift Unit Part A Design a four bit arithmetic shifter that can shift one bit left or right using only pass gates and
one inverter. You only need to connect to the active high side of each pass gate.
I3 I2 I1 I0 Right/Left O3 O2 O1 O0 Part B Using the inputs and outputs of the shift unit in part A, design logic which produces an error
signal when shifting four bit two's compliment numbers. The output of this logic Error is high when an error results from the shift. Note: rounding fractional number is not an error. ...
