Design of novel high speed parallel prefix adder

Design and Implementation of High Speed Parallel Prefix Ling Adder

Parallel-prefix adders offer a highly efficient solution to the binary addition problem and are well-suited for VLSI implementations. In this paper, a novel framework is introduced, which allows the design of parallel-prefix Ling adders. The proposed approach saves one-logic level of implementation compared to the parallelprefix structures proposed for the traditional definition of carry look a...

High Speed radix256 algorithm using parallel prefix adder

An efficient model for design of 64 - bit High Speed Parallel Prefix VLSI adder

To make addition operations more efficient parallel prefix addition is a better method. In this paper 64-bit parallel prefix addition has been implemented with the help of cells like black cell and grey cell operations for carry generation and propagation. This process gives high speed computations with high fan-out and makes carry operations easier. Xilinx 14.1 vivado tool has been used for th...

A Novel Power Delay Optimized 32-bit Parallel Prefix Adder For High Speed Computing

Parallel Prefix addition is a technique for improving the speed of binary addition. Due to continuing integrating intensity and the growing needs of portable devices, low-power and high-performance designs are of prime importance. The classical parallel prefix adder structures presented in the literature over the years optimize for logic depth, area, fan-out and interconnect count of logic circ...

4 Parallel Prefix Adder

VLSI Integer adders find applications in Arithmetic and Logic Units (ALUs), microprocessors and memory addressing units. Speed of the adder often decides the minimum clock cycle time in a microprocessor. The need for a Parallel Prefix Adder (PPA) is that it is primarily fast when compared with a ripple carry adder. PPA is a family of adders derived from the commonly known carry look ahead adder...
