Barrel shifters are often required for performing data shifting and rotation in many key computer operations from address decoding to computer arithmetic. In this paper, the authors present a comparative study of various parameters like delay, power and area, for a high performance 16-bit barrel shifter VLSI implementations using three different logic design styles (conventional CMOS, transmission gate CMOS and Dual rail Domino CMOS logic) in 0.6mm, N-well CMOS process. The proposed barrel shifter implementations shows better performance as compared to implementation by the researcher.
