Reversible logic is of the growing importance to many future technologies. A reversible circuit maps each output vector, into a unique input vector, and vice versa. This paper introduces an approach to synthesise the generalized multi-rail reversible cascades and minimizing the "garbage bit" and num...

A set of p-valued logic gates (primitives) is called universal if an arbitrary p-valued logic function can be realized by a logic circuit built up from a finite number of gates belonging to this set. In this paper, we consider the problem of determining the number of universal single-gate libraries ...

Irreversible logic circuits dissipate heat for every bit of information that is lost. Information is lost when the input vector cannot be recovered from its corresponding output vector. Reversible logic circuit naturally takes care of heating because it implements only the functions that have one-to...
