Programmable Logic Devices (PLDs) have become the key implementation medium for the vast majority of digital circuits designed today. While the highest-volume devices are still built with full-fabrication rather than field­ programmability, the trend towards ever fewer ASICs and more FPGAs is clear. This makes the field of PLD architecture ever more important, as there is stronger demand for faster, smaller, cheaper and lower-power programmable logic. PLDs are 90% routing and 10% logic. This book focuses on that 90% that is the programmable routing: the manner in which the programmable wires are connected and the circuit design of the programmable switches themselves. Anyone seeking to understand the design of an FPGA needs to become lit­ erate in the complexities of programmable routing architecture. This book builds on the state-of-the-art of programmable interconnect by providing new methods of investigating and measuring interconnect structures, as well as new programmable switch basic circuits. The early portion of this book provides an excellent survey of interconnec­ tion structures and circuits as they exist today. Lemieux and Lewis then provide a new way to design sparse crossbars as they are used in PLDs, and show that the method works with an empirical validation. This is one of a few routing architecture works that employ analytical methods to deal with the routing archi­ tecture design. The analysis permits interesting insights not typically possible with the standard empirical approach.

David Lewis and his small yacht, ICE BIRD, set sail from Sydney, Australia, on a search for high adventure. Their voyage, full of drama, emotion, and pain, took them to one of the least hospitable and most fascinating parts of the globe – the Antarctic. No one had ever sailed a yacht single-handed to Antarctica before David Lewis. For more than fourteen weeks, he never once touched land. He faced mountainous seas, constant gales, snow storms, and freezing temperatures; twice his small yacht capsized, and once it was dismasted 3,500 miles from help. He survived through a miracle of fortitude, skill, and luck. One of the great true sea stories of the twentieth century, ICE BIRD is a gripping tale of human endurance, a testimony to one man's will to overcome any obstacle – whether physical or psychological – to stay alive. “It was an epic more than 30 years ago, and remains so. Time has not dimmed the achievement, nor diminished the power of the story. It is as gripping, awesome, and ‘living,’ today, as it was then.” —Sailing & Yachting

Convention was immediately recognized as a major contribution to the subject and its significance has remained undiminished since its first publication in 1969. Lewis analyzes social conventions as regularities in the resolution of recurring coordination problems-situations characterized by interdependent decision processes in which common interests are at stake. Conventions are contrasted with other kinds of regularity, and conventions governing systems of communication are given special attention.

This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.

Outlines the proceedings of the conference on 'Quadratic Forms and Their Applications' held at University College Dublin. This work includes survey articles and research papers ranging from applications in topology and geometry to the algebraic theory of quadratic forms and its history.

Counterfactuals is David Lewis' forceful presentation of and sustained argument for a particular view about propositions which express contrary to fact conditionals, including his famous defense of realism about possible worlds.

Based on interviews with people throughout Siberia, Central Asia and European Russia about their spiritual experiences, this book brings together insights into the 'religious' worldview of those who claim to be Buddhist, Muslim, Christian, pagan or even 'atheist'. Throughout the ex-Soviet Union peoples of many different ethnic backgrounds report such experiences but often do not know how to interpret them, a position helped or hindered by the fact that at the same time these people are trying to rediscover their ethnic and cultural identity.

This volume is devoted to Lewis's work in ethics and social philosophy. Topics covered include the logic of obligation and permission; decision theory and its relation to the idea that beliefs might play the motivating role of desires; a subjectivist analysis of value; dilemmas in virtue ethics; the problem of evil; problems about self-prediction; social coordination, linguistic and otherwise; alleged duties to rescue distant strangers; toleration as a tacit treaty; nuclear warfare; and punishment. This collection, and the two preceding volumes, will disseminate more widely the work of an eminent and influential contemporary philosopher.

This volume is devoted to Lewis's work in metaphysics and epistemology. Topics covered include properties, ontology, possibility, truthmaking, probability, the mind-body problem, vision, belief, and knowledge. The purpose of this collection, and the volumes that precede and follow it, is to disseminate more widely the work of an eminent and influential contemporary philosopher. The volume will serve as a useful work of reference for teachers and students of philosophy.

This is the first of a three-volume collection of David Lewis’s most recent papers in all the areas to which he has made significant contributions. The purpose of this collection (and the two volumes to follow) is to disseminate even more widely the work of a preeminent and influential late twentieth-century philosopher. The papers are now offered in a readily accessible format. This first volume is devoted to Lewis’s work on philosophical logic from the last twenty-five years. The topics covered include: deploying the methods of formal semantics from artificial formalised languages to natural languages, model-theoretic investigations of intensional logic, contradiction, relevance, the differences between analog and digital representation, and questions arising from the construction of ambitious formalised philosophical systems. The volume will serve as an important reference tool for all philosophers and their students.

This book provides an introduction to matrix theory and aims to provide a clear and concise exposition of the basic ideas, results and techniques in the subject. Complete proofs are given, and no knowledge beyond high school mathematics is necessary. The book includes many examples, applications and exercises for the reader, so that it can used both by students interested in theory and those who are mainly interested in learning the techniques.
