Bit shifting circuit

A barrel shifter is often used to shift and rotate n-bits in modern microprocessors, [citation needed] typically within a single clock cycle. For example, take a four-bit barrel shifter, with inputs A, B, C and D. The shifter can cycle the order of the bits ABCD as DABC, CDAB, or BCDA; in this case, no bits are lost. That … See more 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, only pure combinational logic, i.e. it inherently provides a binary operation. It can however in … See more The number of multiplexers required for an n-bit word is $${\displaystyle n\log _{2}n}$$. Five common word sizes and the number of multiplexers needed are listed below: • 128-bit — $${\displaystyle 128\times \log _{2}128=128\times 7=896}$$ • 64-bit — See more • Kroening, Daniel; Strichman, Ofer (2008).
