Study and Analysis of Low Power Barrel Shifter Using CMOS Technology

Abstract

Abstract—Data computing and high-speed digital signal processing (DSP) rely heavily on bit manipulation, which includes pivot and shift operations. The most common tool for accomplishing these tasks efficiently is the barrel shifter. One potential alternative technology to complementary metal-oxide semiconductors (CMOS) for designing high-speed circuits is nanomagnetic logic circuits. A combinational circuit is the most common type of nano-magnet circuit now in use. In this study, an in-plane nanomagnetic logic-based barrel shifter is developed and produced. Barrel shifters/rotators can be used with 2:1, 4:1, 8:1, etc. multiplexer units to perform shifting and rotating operations independently or simultaneously. The multiplexer unit allows the barrel shifter/rotator to utilize it again, which reduces power consumption. Nano-magnetic logic circuits have never before been suggested. For the RISC processor to run as efficiently as possible, the Barrel Shifter is an essential component; it rotates and transfers data in both the left and right directions.
