Reversible logic circuits have drawn attention from a variety of fields, including nanotechnology, optical computing, quantum computing, and low-power CMOS design. Low-power and high-speed adder cells (like the BCD adder) are used in binary operation-based electronics. The most fundamental digital circuit activity is binary addition. It serves as a foundation for all subsequent mathematical operations. The main challenge today is to reduce the power consumption of adder circuits while maintaining excellent performance over a wide range of circuit layouts. Error detection in digital systems is aided by parity preservation. This article proposes a concept for a fault-tolerant parity- preserving BCD adder. To reduce power consumption and circuit quantum cost, the proposed method makes use of reversible logic gates like IG, FRG, and F2G. Comparing the proposed circuit to the current counterpart, it has fewer constant inputs and garbage outputting devices and is faster.

In recent years, there has been an increasing tendency towards designing circuits based on reversible logic, and has received much attention because of preventing internal power dissipation. In digital computing systems, multiplier circuits are one of the most fundamental and practical circuits used in the development of a wide range of hardware such as arithmetic circuits and Arithmetic Logic Unit (ALU). Vedic multiplier, which is based on Urdhva Tiryakbhayam (UT) algorithm, has many applications in circuit designing because of its high speed in performing multiplication compared to other multipliers. In Vedic multipliers, partial products are obtained through vertical and cross multiplication. In this paper, we propose four [Formula: see text] reversible Vedic multiplier blocks and use each one of them in its right place. Then, we propose a [Formula: see text] reversible Vedic multiplier using the four aforementioned multipliers. We prove that our design leads to better results in terms of quantum cost, number of constant inputs and number of garbage outputs, compared to the previous ones. We also expand our proposed design to [Formula: see text] multipliers which enable us to develop our proposed design in every dimension. Moreover, we propose a formula in order to calculate the quantum cost of our proposed [Formula: see text] reversible Vedic multiplier, which allows us to calculate the quantum cost even before designing the multiplier.

In network routers, Ternary Content Addressable Memory (TCAM)[1] based search engines take an important role. One of the improved versions of Content Addressable Memory (CAM) is TCAM. For high speed and broader searching operation TCAM is used. Unlike normal CAM, TCAM has 3 logic states: 0, 1, ‘X’. In TCAM within one single clock cycle, search operation can be performed. That is why it is called special type of memory. Also, quick search ability is one of the popular features of TCAM. To compare the search and stored data, TCAM array acts parallel in every location. But high power dissipation is the main disadvantage of TCAM. To overcome this power dissipation in this paper we proposed a low power TCAM implementation by using Reversible logic.[2] Reversible logic has less heat dissipating characteristics property with respect to irreversible gate. Also, Reversible logic has ultra-low power characteristics feature. In recent past it has been proved that reversible gates can implement any Boolean function.

Recently, low-power consuming devices are gaining demand due to excessive use and requirement of hand-held & portable electronic gadgets. The quest for designing better options to lower the power consumption of a device is in high-swing. The paper proposes two 32 x 32 – bit multipliers. The first design is based only on the Urdhava Tiryakbhyam Sutra of Vedic Mathematics. The use of this sutra has created a multiplier with higher throughput and lesser power utilization than conventional 32 x 32 – bit multipliers. The second design incorporates the reversible logic into the first design, which further reduces the power consumption of the system. Thus bringing together Vedic sutra for multiplication and reversible gates has led to the development of a Reversible Vedic Multiplier which has both the advantages of high-speed and low-power consumption.
