Reversible logic circuits are of interests to power minimization having applications in low power CMOS design, optical information processing, DNA computing, bioinformatics, quantum computing and nanotechnology. In this paper we propose a novel 4x4 bit reversible multiplier circuit. The proposed reversible multiplier is faster and has lower hardware complexity compared to the existing counterpa...

Many universal reversible libraries that contain more than one gate type have been proposed in the literature. Practical implementation of reversible circuits is much easier if a single gate type is used in the circuit construction. This paper proposes a reversible n-bit gate that is universal for reversible circuits synthesis. The proposed gate is extendable according to the size of the circui...

Field programmable gate arrays (FPGA) are increasingly being used in the high performance and scientific computing community to implement floating-point based system. The reversible single precision floating point multiplier (RSPFPM) requires the design of reversible integer multiplier (2424) based on operand decomposition approach. Reversible logic is used to reduce the power dissipation than...

In modern technologies, management of energy loss is an important issue in digital logic design for both the manufacturer and the customer. A part of energy dissipation may occur because of nonideality of switches or devices. With the exponential growth of packing density, the traditional technologies like CMOS are reaching to a limit. So some alternative technology is required to overcome from...

In recent years, reversible logic has emerged as a promising computing paradigm having its applications in low power computing, quantum computing, nanotechnology, optical computing and DNA computing. The classical set of gates such as AND, OR, and EXOR are not reversible. Recently, it has been shown how to encode information in DNA and use DNA amplification to implement Fredkin gates. Furthermo...

The paper discusses the asymptotic depth of a reversible circuit consisting of NOT, CNOT and 2-CNOT gates. Reversible circuit depth function $D(n, q)$ for a circuit implementing a transformation $f\colon \mathbb Z_2^n \to \mathbb Z_2^n$ is introduced as a function of $n$ and the number of additional inputs $q$. It is proved that for the case of implementing a permutation from $A(\mathbb Z_2^n)$...

We present new algorithms to synthesize exact universal reversible gate library for various types of gates and costs. We use the powerful algebraic software GAP for implementation and examination of our algorithms and the reversible logic synthesis problems have been reduced to group theory problems. It is shown that minimization of arbitrary cost functions of gates and orders of magnitude are ...
