High-Speed VLSI Arithmetic Units: Adders and Multipliers


Introduction

Digital computer arithmetic is an aspect of logic design with the objective of developing
appropriate algorithms in order to achieve an efficient utilization of the available hardware .
Given that the hardware can only perform a relatively simple and primitive set of Boolean
operations, arithmetic operations are based on a hierarchy of operations that are built upon the
simple ones. Since ultimately, speed, power and chip area ar ....etc

INSTRUCTOR’S MANUAL FORVolume 2: Presentation Material



Preface to the Instructor’s Manual
This instructor’s manual consists of two volumes. Volume 1 presents solutions to selected
problems and includes additional problems (many with solutions) that did not make the cut for
inclusion in the text Computer Arithmetic: Algorithms and Hardware Designs (Oxford
University Press, 2000) or that were designed after the book went to print. Volume 2 contains

Abstract
In this paper, we review the logical effort model presented in . Based on the HSPICE simulation results using 0.18/Jm, CMOS technology as applied to logic blocks used in arithmetic circuits; we analyze the efficiency of the model and also present modifications that include modeling of wire delay. We propose a new model for logical effort that will better fit the behavior of these blocks. The results are applicable for evaluation of arithmetic units as well as for development of new arithmetic algorithms. Our ultimate objective is ....etc

Simple Hardware-Oriented Algorithms For Cellular Mobiles Positioning
Abstract
Locating a mobile station position is one of the most significant features of cellular mobile phones in wireless communications. All location determination algorithms are based on trigonometric calculations which are usually implemented in software.This seminar propose two new hardware oriented algorithms that use just simple add, shift and subtract operations in finding the location of a mobile station. The first algorithm uses fixed rotations to ....etc

1. INTRODUCTION
An arithmetic-logic unit (ALU) is the part of a computer processor (CPU) that carries out arithmetic and logic operations on the operands in computer instruction words. In some processors, the ALU is divided into two units, an arithmetic unit (AU) and a logic unit (LU). Some processors contain more than one AU - for example, one for fixed-point operations and another for floating-point operations.
Generally ar ....etc

Optimal Designs and Comparison of the Doubly
Salient Permanent Magnet Machine and
Flux-reversal Machine in Low-speed Applications

Abstract
The subject of this is to optimize the design and to compare
The performances of a low-speed doubly salient permanent magnet machine with
Those of a low-speed flux-reversal machine devoted to direct drive applications. The
Optimization, focused on the maximization of the machines mass-to-torque ratio,
is done by a genetic algorithm combined with the finite-element method (FEM) ....etc
