The number of 1-bit shifters are required to design the mentioned eight shift control inputs is 12.
What is barrel shifter?
A barrel shifter is a digital circuit that can shift a data word by a specified number of bits without the use of any sequential logic.
Design a simple FSM to determine the number of 1-bit shifters are required to design the mentioned barrel shifter
x = 0 x = 0 x = 1 x = 1
y = 0 y = 1 y = 0 y = 1
z = 0 z = 1 z = 1 z = 1
number of 1-bit shifters required = 3 x 4 = 12
Thus, the number of 1-bit shifters are required to design the mentioned eight shift control inputs is 12.
