In recent years low power and small size are the keyword in the IC industry. This is where the importance of reversible gate and QCA (Quantum dot cellular automata) comes in. In nonreversible gates there is a definite amount of power loss involved. Interest in reversible computation arises from the desire to reduce heat dissipation, thereby allowing – higher densities and higher speed. The QCA ...

Owing to the exponential nature of the memory and run-time complexity, many methods can only synthesize 3-bit reversible circuits and cannot synthesize 4-bit reversible circuits well. We mainly absorb the ideas of our 3-bit synthesis algorithms based on hash table and present the efficient algorithms which can construct almost all optimal 4-bit reversible logic circuits with many types of gates...

Quantum dot cellular Automata (QCA) is leading technology for alternative of CMOS design. Reversible Logic design is found to be Low power design which becomes emerging technology in Low power Nanotechnology era. In this work we devoted to design a Reversible Logic Gate which is a universal gate (known as URLG) and can be design with alternative of co-planer cross over wire. We introduce a pass...

Background: The SubBytes and InvSubBytes transformations of Advanced Encryption Standard (AES) algorithm are conventionally implemented by using either look-up tables or combinational logic circuits. Both implementations are susceptible to power analysis attacks as they consume substantial amount of power during their normal operation. Objective: To overcome the power analysis attacks in SubByt...

Conventional logic dissipates more power by losing bits of information whereas reversibility recovers bit loss from the unique input-output mapping. Reversible Computation has high promise of low power consumption. In this paper, we have proposed a new 4x4 reversible gate (namely BJ gate) which is used to design reversible J-K flip-flop. We have also proposed the design of low power reversible ...

Abstract: Reversible circuits are currently on of top approaches to power minimization and the one whose importance will be only growing with time. In this paper, the well known Feynman gate is generalized to k*k gate and a new generalized k*k family of reversible gates is proposed. A synthesis method for multi-output SOP function using cascades of the new gate family is presented. For utilizin...

A Fault tolerant reversible logic has gained importance as they consume low power and less heat dissipation. The benefits of logical reversibility can be gained only after employing physical reversibility. Every future technology will have to use reversible gates in order to reduce power. This paper proposed a new fault tolerant reversible 4*4 RR-gate which satisfies the reversible and parity p...

The atomistic quantum-dot cellular automata (QCA) based implementations of the reversible circuits have got tremendous exposures in the last few days, due to “room-temperature workability” of the QCA. The researchers are in serious need of a methodology that can realize the area-efficient QCA counterparts of reversible benchmark circuits. In this work, a novel methodology named majoritylayered ...

Reversible logic is one of the new paradigms for power optimization that can be used instead of the current circuits. Moreover, the fault-tolerance capability in the form of error detection or error correction is a vital aspect for current processing systems. In this paper, as the multiplication is an important operation in computing systems, some novel reversible multiplier designs are propose...
