Abstract :
This paper compares a new VLSI shifter topology based on an inverse butterfly network with a conventional barrel shifter using a structured custom CMOS design approach. The inverse butterfly network circuit is found to be larger and slower than a barrel shifter for both uni-directional and bi-directional rotations.
