Design and Implementation of Ternary Bidirectional Barrel Shifter Using Multi-Valued Reversible Logic

Sunil Thomas Paul, M. Rajmohan

Abstract: Reversible logics are a promising application for low power computing, quantum computing and other emerging computing technologies. The application of multi-valued logic reduces the width of reversible and quantum computing gates. Barrel shifters are being used for high speed data shifting. In this paper, we propose a ternary bidirectional barrel shifter design which is a combination of Ternary Feynman and Modified Fredkin Gate. The proposed design is evaluated in terms of Operations, Garbage outputs, Quantum cost and the number of Ancilla inputs.

Keywords: Quantum cost, Ancilla inputs, Garbage output, Modified Fredkin gate, Ternary Feynman gate
