Reversible logic functions can be realized as networks of Toffoli gates. The synthesis of To oli networks can be divided into two steps. First, nd a network that realizes the desired function is determined. Second, transform the network such that it uses fewer gates, while realizing the same function. This paper addresses the second step. Transformations are accomplished via template matching. ...

Filters are widely used in the world of communication and computation. To design a finite impulse response (FIR) filter that satisfies all the required conditions is a challenge. Power consumption by the multiplier and adder blocks in the architecture is the prime cause for concern in FIR design. In this paper, design of an FIR filter entirely using Reversible logic is presented. Reversible log...

The paper describes the design of programmable reversible logic gate structures, targeted for the ALU implementation and their use in the realization of an efficient reversible ALU. Using reversible logic gates instead of traditional logic AND/OR gates, a reversible ALU whose function is the same as traditional ALU is constructed. Comparing with the number of input bits and the discarded bits o...

Reversible Logic is gaining significant consideration as the potential logic design style for implementation in modern nanotechnology and quantum computing with minimal impact on physical entropy .Fault Tolerant reversible logic is one class of reversible logic that maintain the parity of the input and the outputs. Significant contributions have been made in the literature towards the design of...

Block cellular automata (BCA) make local, parallel, synchronous and uniform updates of innnite lattices. In the one-dimensional case, there exist BCA with 11 states which are universal for computation. The Billiard ball model of Margolus is a reversible two-dimensional BCA which is able to simulate any two-register automaton and is thus universal. This simulation is achieved by embedding a logi...
