Conservative and reversible logic gates are widely known to be compatible with revolutionary computing paradigms such as optical and quantum computing. A fundamental conservative reversible logic gate is the Fredkin gate. This paper presents efficient adder circuits based on the Fredkin gate. Novel full adder circuits using Fredkin gates are proposed which have lower hardware complexity than th...

Over the last two decades, FIR filters have been subject of intense research. The design an adder, which is a major building component in circuit design, determines overall performance system. Finite Impulse Response (FIR) filter has increasingly popular signal processing applications recent years. For field and VLSI systems, many adders are implemented. Signal denoising, as well production eff...

Montgomery modular multiplication is one of the fundamental operations used in cryptographic algorithms, such as RSA and Elliptic Curve Cryptosystems. The previous Montgomery multipliers perform a single Montgomery multiplication in approximately 2n clock cycles and it requires more number of addition stages for large word length additions, where n is the size of operands in bits. In this paper...

In asynchronous systems, average function delays principally govern overall throughput. This paper compares the performance of six adder designs with respect to their average delays. Our results show that asynchronous addres (32 or 64-bits) with a hybrid structure (e.g., carry-select addres) run 20-40% faster than simple ripplecarry addres. Hybrid adders also outperform high-cost, strictly sync...

This paper presents a comparative research of low-power and high-speed 4-bit full adder circuits. The representative adders used are a ripple carry adder (RCA) and a carry-lookahead adder (CLA). We also design a proposed carrylookahead adder (PCLA) using a new method that uses NAND gate for modification which helps in reducing the powerdelay product (PDP) for high performance applications. To y...

The growing design complexity has attracted the designs with Reconfigurable fabrics, where adaptable fabrics are utilized to solve the computational problems. Reconfigurable computing provides the flexibility in arriving at the problem specific architectures which helps in improving the performance due to custom approach. In this paper, a flexible reconfigurable architecture with different adde...

Addition is one of the vital parts of any electronic system design because every electronic system needs this basic operation. Researchers have done a lot of work on various adders to optimise their performance. So, they found that Carry Save adder is best in terms of delay calculation and power consumption. That is why this proposed work use this adder. This paper is primarily focus on design ...
