vhdl code for radix 16 booth multiplier

ABSTRACT:

Low power consumption and smaller area are some of the most important criteria for the fabrication of DSP systems and high performance systems. Optimizing the speed and area of the multiplier is a major design issue. However, area and speed are usuallyconflicting constraints so that improving speed results mostly in larger areas. In our project we try to determine the best solution to this problem by comparing a few multipliers. This project presents an efficient implementation of high speed m ....etc

Introduction

This report presents three main topics we investigated as part of a project to build a Booth encoded multiply/accumulate VLSI chip. The original scope of work included synthesizing VHDL code using the Mentor Graphics tools. Exemplar was the VHDL compiler. Leonardo Spectrum was the synthesizer. Since my team, which included Kevin Delaney, did not meet a Mosis deadline our chip funding was lost. Since we did not actually fabricate a chip, we cannot discuss the success of our results. Likewise, VHDL synthesis using the Exemp ....etc

radix 8 booth multiplier verilog code

Abstract

Novel multi-modulus designs capable of performing the desired modulo operation for more than one modulus in Residue Number System (RNS) are explored in this paper to lower the hardware overhead of residue multiplication. Two multi-modulus multipliers that reuse the hardware resources amongst the modulo 2n-1, modulo 2n and modulo 2n+1 multipliers by virtue of their analogous number theoretic properties are proposed. The former employs the radix- 22 Booth encoding algorithm and the latter employs t ....etc
