Design and Comparison of Reversible and Irreversible Sequential Logic Circuits
S Nagarjun, R. Nagendra, Nagulapati Kiran · 2014
Reversible or information-lossless circuits have applications in digital signal processing, communication, computer graphics and cryptography. They are also a fundamental requirement in the emerging field of quantum computation. We investigate the synthesis of reversible circuits that employ a minimum number of gates and contain no redundant input-output line-pairs. It is not possible to realize quantum computing without implementation of reversible logic. The main purposes of designing reversible logic are to decrease quantum cost, depth of the circuits and the number of garbage outputs. A Fault tolerant reversible logic has gained importance as they consume low power and less heat dissipation. The benefits of logical reversibility can be gained only after employing physical reversibility. Every future technology will have to use reversible gates in order to reduce power. In this paper, we have designed RS flip flop, D flip flop by using reversible gate. The proposed designs are better than the existing proposed ones in terms of number of reversible gates and garbage outputs. So, this realization is more efficient and less costly than other realizations.
