Design Of A Optimized Parallel Array Multiplier Using Parallel Prefix Adder

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...

A Fast and Energy Efficient Radix-8 Booth Multiplier using Brent kung Parallel prefix Adder

An exceptional moduli set Residue Number System (RNS) of high element go (DR) can accelerate the execution of very large word-length tedious increases found in applications like open key cryptography. The modulo 2-1 multiplier is normally the noncritical data path among all modulo multipliers in such high-DR RNS multiplier. This planning slack can be abused to diminish the framework region and ...

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...

Parallel Prefix Speculative Han Carlson Adder

Binary addition is one of the most important arithmetic function in modern digital VLSI systems. Adders are extensively used as DSP lattice filter where the ripple carry adders are replaced by the parallel prefix adder to decrease the delay. The requirement of the adder is fast and secondly efficient in terms of power consumption and chip area. Speculative variable latency adders have attracted...
