Abstract: The paper introduces two innovations in the design of prefix adder carry trees: use of high-valency prefix cells to achieve low logical depth and end-around carry adders with reduced fan-out ...

Abstract: One of the essential components of applications like signal processing, adders play a crucial role. Integrated circuits are the main technology used in the modern world, and adder modules ...

A Kogge-Stone adder is a parallel prefix form carry look-ahead adder. It was developed by Peter M. Kogge and Harold S. Stone in 1973. This adder is known for its speed and efficiency in performing ...

Description for 32-bit Brent-Kung Adder A 32-bit Brent-Kung Adder is a parallel prefix adder designed for high-speed binary addition. It efficiently computes the carry signals required for addition ...

This paper presents a novel low-delay 4-bit Parallel Prefix Adder (PPA) implemented as a multilayer circuit using Quantum Dot Cellular Automata (QCA) technology. PPAs are among the most suitable ...

Basically in digital system there are two type of circuit: combinational logic circuit and sequential logic circuit. When the authors talk about combinational circuit, this circuit is that circuit of ...

In this paper, design of 32-bit parallel multiplier is presented, by introducing Carry Save Adder (CSA) in partial product lines. The multiplier given in this paper is modeled using VHDL (Very High ...

The design and optimisation of low-power full adders is a critical endeavour in modern electronic engineering. Full adders form the backbone of arithmetic logic units, performing essential binary ...
