Abstract: The reversible logic has the promising applications in emerging computing paradigm such as quantum computing, quantum dot cellular automata, optical computing, etc. In reversible logic gates there is a unique one-to-one mapping between the inputs and outputs. Barrel shifter is an integral component of many computing systems due to its useful property that it can shift and rotate multiple bits in a single cycle. The design methodologies considered in this work targets 1.) Reversible logical right shifter, 2.) Reversible universal right shifter that supports logical right shift, arithmetic right shift and the right rotate, 3.) Reversible bidirectional logical shifter, 4.)Reversible bidirectional arithmetic and logical shifter, 5) Reversible universal bidirectional shifter that supports bidirectional logical and arithmetic shift and rotate operations.
