Fundamental of reversible logic

Abstract

All classical logic circuits are physically irreversible, because these circuits comprise irreversible logic. With irreversible logic, all the energy transferred by the power supply is finally converted into heat. Irreversible logic does not allow traverse the state sequences in the reverse direction to gain the initial state after the end of logical computation. This chapter discusses different aspects of both irreversible and reversible logic gates. © Springer Nature Singapore Pte Ltd 2020.
