Delay-Optimistic Multiplier Design using Parallel Prefix Adder with Compressors

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 of Wallace Tree Multiplier using Compressors

A multiplier is one of the key hardware blocks in most digital and high performance systems such as FIR filters, digital signal processors and microprocessors etc. With advances in technology, many researchers have tried and are trying to design multipliers which offer either of the followinghigh speed, low power consumption, regularity of layout and hence less area or even combination of them ...

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...
