Abstract

In recent years, reversible logic has emerged as a promising computing paradigm having application in low power CMOS, quantum computing, nanotechnology, and optical computing. The classical set of gates such as AND, OR, and EXOR are not reversible In this paper, different type of counters designed using reversible Fredkin and Feynman gates(tested using electronic workbench v5.12)It is demonstrated that the counter architectures designed using the proposed gate are much better and optimized, compared to their existing counterparts in literature; in terms of number of reversible gates and garbage outputs. Thus, this paper provides the initial threshold to building of more complex system which can execute more complicated operations using reversible logic.

Abstract

Before built any complex logic system we must find all the possible way to establish this system with minimum logic components so, in this paper we design and implement intelligent program (using DELPHE programming language), this program work on simplifying and drawing any logic equation according to knowledge base built from Boolean algebra rules.
