Reversible logic circuits have found emerging attention in nanotechnology, quantum computing and low power CMOS designs. In this paper we present a modular synthesis method to realize a reversible Binary Coded Decimal (BCD) adder/subtractor circuit. We use genetic algorithms and don’t care concept to design and optimize all parts of a BCD adder circuit in terms of number of garbage inputs/outpu...

Power dissipation has become one of the major concerns of VLSI circuit design with the rapid launching of battery operated applications. In high performance designs, the leakage component of power consumption is comparable to the switching component. This percentage will increase with technology scaling unless effective techniques are introduced to bring leakage under control. In this paper, a ...

Quantum-dot cellular automaton (QCA) is an up-coming nanotechnology in the area of nanoelectronics and is found to be an alternative solution to replace conventional CMOS technology for several reasons. It has attractive features such as faster speed, smaller size, and low power consumption compared to transistor-based technology. The experiments carried out in QCA demonstrated and realized the...

In this paper, we propose an efficient design of a reversible single precision floating point multiplier based on compressor. The single precision floating point multiplier requires the design of an efficient 24x24 bit integer multiplier. In the proposed architecture, the 24x24 bit multiplication operation is fragmented to nine parallel reversible 8x8 bit multiplication modules. In this paper, ...

Floating Point (FP) arithmetic is widely used in large set of scientific and signal processing computation. Adder/subtractor is one of the common arithmetic operation in these computation. The design of FP adder/subtractor is relatively complex than other FP arithmetic operations. This paper has shown an efficient implementation of adder/subtractor module on a reconfigurable platform, which is ...

Over the past decade, DNA has demonstrated remarkable potential in fabrication of molecular logic and arithmetic systems. In this work, a simple DNA-based system mimicking a full-subtractor that handles three inputs including one minuend and two subtrahends for eight input/output conditions is successfully designed. The whole system is established by one gate molecule and three input sequences,...

This work demonstrates two DNA-based logic circuits that behave as a half-adder and a half-subtractor. A half-adder is composed of an AND gate and an XOR gate, whereas a half-subtractor consists of an INH gate and an XOR gate. The proposed designs are inspired by molecular beacons.
