Abstract

A technique for on-line testable reversible logic circuit is presented. Three new reversible logic gates have been introduced in this paper. These gates can be used to implement reversible digital circuits of various levels of complexity. The major feature of these gates is that they provide online testability for circuits implemented using them. The application of these gates in implementation of a subset of MCNC benchmark circuits is provided.
