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

INTRODUCTION
The prolific growth in semiconductor device industry has led to the advancement of high performance
portable systems with heighten reliability in data transmission. Multiplication is a heavily used arithmetic
operation that figures distinguished in signal processing and scientific applications. Typical DSP applications
where a multiplier plays an important role include digital filtering, digital communications and spectral analysis.
Many current DSP applications are aimed at portable, battery-operated systems, so that power di ....etc

32 bit vedic multiplier verilog code

Abstract

Binary multipliers and addresses are used in the design and development of Arithmetic Logic Unit (ALU), Digital Signal Processing (DSP) Processors, Multiply and Accumulate (MAC).The objective of this paper is to implement digital multipliers based on the concept of Vedic mathematics. In order to develop a digital multiplier, Urdhva-tiryakbyham sutra of Vedic mathematics is used to implement vertical and cross wise operations. Since these are digital multipliers, they are implemented on FPGA board ....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
