Book Description
Designing VLSI systems represents a challenging task. It is a transfonnation among different specifications corresponding to different levels of design: abstraction, behavioral, stntctural and physical. The behavioral level describes the functionality of the design. It consists of two components; static and dynamic. The static component describes operations, whereas the dynamic component describes sequencing and timing. The structural level contains infonnation about components, control and connectivity. The physical level describes the constraints that should be imposed on the floor plan, the placement of components, and the geometry of the design. Constraints of area, speed and power are also applied at this level. To implement such multilevel transfonnation, a design methodology should be devised, taking into consideration the constraints, limitations and properties of each level. The mapping process between any of these domains is non-isomorphic. A single behavioral component may be transfonned into more than one structural component. Design methodologies are the most recent evolution in the design automation era, which started off with the introduction and subsequent usage of module generation especially for regular structures such as PLA's and memories. A design methodology should offer an integrated design system rather than a set of separate unrelated routines and tools. A general outline of a desired integrated design system is as follows: * Decide on a certain unified framework for all design levels. * Derive a design method based on this framework. * Create a design environment to implement this design method.

Book Description
This book is the first in a set of forthcoming books focussed on state-of-the-art development in the VLSI Signal Processing area. It is a response to the tremendous research activities taking place in that field. These activities have been driven by two factors: the dramatic increase in demand for high speed signal processing, especially in consumer elec tronics, and the evolving microelectronic technologies. The available technology has always been one of the main factors in determining al gorithms, architectures, and design strategies to be followed. With every new technology, signal processing systems go through many changes in concepts, design methods, and implementation. The goal of this book is to introduce the reader to the main features of VLSI Signal Processing and the ongoing developments in this area. The focus of this book is on: • Current developments in Digital Signal Processing (DSP) pro cessors and architectures - several examples and case studies of existing DSP chips are discussed in Chapter 1. • Features and requirements of image and video signal processing architectures - both applications specific integrated circuits (ASICs) and programmable image processors are studied in Chapter 2. • New market areas for signal processing - especially in consumer electronics such as multimedia, teleconferencing, and movie on demand. • Impact of arithmetic circuitry on the performance of DSP pro cessors - several topics are discussed in Chapter 3 such as: number representation, arithmetic algorithms and circuits, and implementa tion.

Book Description
La transformation de Fourier (Vol. IV et VI) est un outil très précieux en traitement des signaux, elle intervient en particulier dans l'analyse spectrale, qui en est une application fondamentale. Avec les méthodes classiques, le calcul de cette transforma- tion par voie numérique nécessite un temps de calcul prohibitif. L'algorithme de cal- cul rapide - connu sous le nom de transformation de Fourier rapide (en anglais : Fast Fourier Transform ou FFT) — a permis de réduire considérablement ce temps de calcul. Plusieurs méthodes, en particulier un certain nombre de traitements non linéaires déve- loppés préalablement sur le plan théorique, ont pu être appliquées avec succès grâce à cet algorithme. Le traitement numérique des signaux bidimensionnels — c'est-à-dire des images — a également bénéficié très fortement de cet algorithme, dont l'introduction dans cette discipline a constitué un tournant. Les progrès technologiques continus dans le domaine des circuits intégrés, surtout à large échelle, ont permis la réduction des prix et des dimensions des systèmes numéri- ques, tout en permettant la conception de circuits de plus en plus complexes. C'est ainsi qu'on est passé des ordinateurs aux mini-ordinateurs, dont l'architecture peut être conçue de manière à optimiser les traitements numériques. Actuellement, des organes périphériques spécialisés, de complexité croissante, se développent pour augmenter la vitesse tout en maintenant un coût économiquement admissible. Le développement relativement récent des microprocesseurs a permis une miniaturisation plus grande tout en gardant l'avantage de la souplesse. Parallèlement, des circuits intégrés spécialisés, moins souples mais rapides, ont été développés permettant l'élaboration de systèmes de traitements numériques complexes qui travaillent en temps réel. Aujourd'hui, une gran- de partie des systèmes modernes de transmission de parole, de radar et de sonar sont entièrement numériques. Grâce aux progrès mentionnés précédemment, le traitement numérique de signaux est devenu, de nos jours, une discipline à part entière dont l'im- portance ne fait que croître. C'est pour les raisons citées ci-dessus que le volume XX s'insère dans le Traité d'Electricité, afin de couvrir le volet complémentaire du volume VI, tout en signalant les concepts similaires. Hormis quelques notions fondamentales sur la décomposition en série de Fourier — introduites dans le volume IV et développées dans le volume VI — la lecture du présent volume ne nécessite comme connaissances préalables, que les bases élémentaires de la théorie des probabilités, des fonctions complexes et du calcul matriciel.

Book Description
Symbolic analysis is an intriguing topic in VLSI designs. The analysis methods are crucial for the applications to the parasitic reduction and analog circuit evaluation. However, analyzing circuits symbolically remains a challenging research issue. Therefore, in this book, we survey the recent results as the progress of on-going works rather than as the solution of the field. For parasitic reduction, we approximate a huge amount of electrical parameters into a simplified RLC network. This reduction allows us to handle very large integrated circuits with given memory capacity and CPU time. A symbolic analysis approach reduces the circuit according to the network topology. Thus, the designer can maintain the meaning of the original network and perform the analysis hierarchically. For analog circuit designs, symbolic analysis provides the relation between the tunable parameters and the characteristics of the circuit. The analysis allows us to optimize the circuit behavior. The book is divided into three parts. Part I touches on the basics of circuit analysis in time domain and in s domain. For an s domain expression, the Taylor's expansion with s approaching infinity is equivalent to the time domain solution after the inverse Laplace transform. On the other hand, the Taylor's expansion when s approaches zero derives the moments of the output responses in time domain. Part II focuses on the techniques for parasitic reduction. In Chapter 2, we present the approximation methods to match the first few moments with reduced circuit orders. In Chapter 3, we apply the Y-Delta transformation to reduce the dynamic linear network. The method finds the exact values of the low order coefficients of the numerator and denominator of the transfer function and thus matches part of the moments. In Chapter 4, we handle two major issues of the Y-Delta transformation: common factors in fractional expressions and round-off errors. Chapter 5 explains the stability of the reduced expression, in particular the Ruth-Hurwitz Criterion. We make an effort to describe the proof of the Criterion because the details are omitted in most of the contemporary textbooks. In Chapter 6, we present techniques to synthesize circuits to approximate the reduced expressions after the transformation. In Part III, we discuss symbolic generation of the determinants and cofactors for the application to analog designs. In Chapter 7, we depict the classical topological analysis approach. In Chapter 8, we describe a determinant decision diagram approach that exploits the sparsity of the matrix to accelerate the computation. In Chapter 9, we take only significant terms when we search through determinant decision diagram to approximate the solution. In Chapter 10, we extend the determinant decision diagram to a hierarchical model. The construction of the modules through the hierarchy is similar to the Y-Delta transformation in the sense that a byproduct of common factors appears in the numerator and denominator. Therefore, we describe the method to prune the common factors.
