This paper Proposes 4 bit Barrel Shifter (BS) acting an important role in the data shifting (DS)and data rotation. It is having application in many areas. The BS is mostlyutilized for generalization of DS. The Arithmetic & Logical Shifters can also be exchange by BS cause by rotation of data it also gives application data right, left shifting either arithmetically or logically. The principle of this paper is to propose4 bit BSutilizing universal gates with assist of CMOS logic. The additionalsuperioredition of BS is 4 bit DS that is also projected here. The paper analyzes, optimizes and compares delay andpower of the 4 bit Barrel Shifter using 90 nm and 45nm technologies. Bit-wise function is pivotal whenprogramming hardware registers in embedded method.There are many instances where we need to change only onebit of a complete register, in this case, changing the wholeregister value can be time consuming and undesirable. Bitshifting is one of the many useful bit operations one canperform. In paper it have presents 4 BS which is used in right-shift, left-shift, depending on what user approach&considered its distinctiveness. The simulationresults are carried out using Cadence.
