Design of Low Power Barrel Shifter Architecture by Using Proposed MUX Based CORDIC in CMOS Logic

Shifters usually play an important role in all the operations in VLSI computer systems. For example, barrel shifter is a fundamental block of many computing systems due to its operational operation that it can shift and rotate various multiple bits in one cycle. The barrel shifter can also be replaced for arithmetic and the logical shifters as it uses the rotation of the data. It also provides both the shifting of right and left arithmetically and logically. The design is purely MUX-based, and therefore, designing a MUX for low power to use it as a repetitive block in the barrel shifter will improve its efficiency. In this paper, an 8-bit barrel shifter using multiplexers (MUX) is implemented and is designed in cadence tool for demonstrating in power and its functional operations. The paper analyzes and optimizes the area and power of the barrel Shifter in 180 nm technologies. Cadence Virtuoso tool is used for implementing the block.
