A barrel shifter is a circuit that can shift a data word by a specified number of bits without the use of any sequential logic, only pure combinatorial logic. The main concern of this paper is to design and study about barrel shifter of 8-bit that is used in RISC processor using GDI (Gate-Diffusion-Input) technique. The main objective of this paper is to design a fully custom 8 bit barrel shifter using 8x1 multiplexer with the help of GDI technique and analyze the performance on basis of power consumption and number of transistors. The tool used to fulfill the purpose is Tanner EDA15.1 using 180nm technology.
