This book was released on 1997 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: LES PROGRES TECHNOLOGIQUES CONSTANTS DANS LES DOMAINES DES ASIC ET DES CURS DE PROCESSEURS PERMETTENT D'INTEGRER DES SYSTEMES EMBARQUES DE COMPLEXITE CROISSANTE AU SEIN D'UN MEME CIRCUIT. PAR AILLEURS, DEPUIS QUELQUES ANNEES L'UTILISATION DE SYSTEMES EMBARQUES DEVIENT REGULIERE DANS DE NOMBREUX DOMAINES D'APPLICATION. LEURS IMPLEMENTATIONS NECESSITENT GENERALEMENT LA MISE EN UVRE DE COMPOSANTS HETEROGENES ET LA VERIFICATION DE CONTRAINTES DE CONCEPTION SEVERES (E.G., SURFACE, PERFORMANCE, CONSOMMATION). DE PLUS, LES EXIGENCES DES UTILISATEURS ENTRAINE LA DIMINUTION DES DUREES DE VIE DE CES SYSTEMES EMBARQUES. AINSI, L'IMPORTANCE DE LA CONCEPTION CONJOINTE LOGICIEL/MATERIEL CROIT FORTEMENT AFIN D'AIDER LES CONCEPTEURS A RESPECTER LES CONTRAINTES DE TIME TO MARKET. LA CONCEPTION DES INTERFACES DE COMMUNICATION ENTRE LES COMPOSANTS LOGICIELS ET MATERIELS DE L'ARCHITECTURE GARANTISSANT DES TRANSFERTS DE DONNEES ET DE CONTROLE CORRECTS EST PARTICULIEREMENT LONGUE ET DIFFICILE. AINSI, SUR LA BASE D'UNE ARCHITECTURE GENERIQUE DEDIEE AUX APPLICATIONS EMBARQUEES DE TELECOMMUNICATION ET DE MULTIMEDIA, NOUS PROPOSONS UNE METHODE DE SYNTHESE DES COMMUNICATIONS QUI REALISE LA CARACTERISATION ET L'IMPLEMENTATION DES COMMUNICATIONS DANS L'ARCHITECTURE FINALE. CETTE METHODE PREND PLACE APRES LES ETAPES DE PARTITIONNEMENT ET D'ORDONNANCEMENT ET PEUT CONSTITUER LES FONDEMENTS D'UNE APPROCHE DE CONCEPTION CONDUISANT A L'INTEGRATION LOGICIEL ET MATERIEL D'APPLICATIONS DE TRAITEMENT DU SIGNAL.

Available in PDF, EPUB and Kindle. Book excerpt: La conception des systèmes embarqués représente un défi majeur d'une importance croissante. Les technologies submicroniques permettent de fabriquer des systèmes toujours plus complexes, gagnant de nouveaux marchés dans les domaines des moyens de transport ou des télécommunications, tels que la téléphonie mobile, la télévision numérique, ou le multimédia. Cependant, cette potentialité est de plus en plus sous utilisée, car l'évolution de la capacité à concevoir de tels systèmes n'augmente pas au même rythme. Cette croissante capacité d'intégration accentue le besoin d'une nouvelle méthodologie de conception. L'objectif de cette thèse est de tentes d'apporter des éléments de réponse au problème de la conception des systèmes embarqués. Nous étudions pour ce faire une approche reposant sur la conception concurrente des parties matérielles câblées et des parties logicielles enfouies, en confrontant cette approche à la conception d'un équipement avionique. Cette thèse propose de passer d'une conception de niveau composant vers une conception qui appréhende le problème à partir d'un point de vue plus global : le niveau système. Les bénéfices issus de cette élévation d'abstraction doivent apporter un gain d'optimisation de la conception aussi bien en terme de qualité qu'en terme de productivité. Les étapes d'une méthodologie de codesign incluent au delà de la spécification de l'application au niveau système, un partitionnement matériel/logiciel, une modélisation des architectures potentielles, une sélection de l'architecture, une synthèse concurrente du matériel et du logiciel, et une covérification.

This book was released on 2004 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: La technologie de fabrication des circuits intégrés a permis de passer des composants spécifiques ASIC aux systèmes embarqués sur une seule puce (SoC). Ces systèmes sont construits par un assemblage de composants hétérogènes préconçus. De plus, le flot de conception de SoC nécessite l'intégration de plusieurs outils provenant de différentes sources et ayant des domaines d'application variés, dans le but d'obtenir un flot de conception complet. L'intégration de composants hétérogènes est difficile. Elle requiert une adaptation de leurs interfaces au réseau de communication. Cette adaptation nécessite la construction d'adaptateurs divers et très sophistiqués. Ces derniers sont obtenus par un assemblage de composants d'interface élémentaires. L'intégration d'outils dans un environnement de conception existant est aussi difficile. Elle nécessite une interopérabilité entre les différents outils dans le cadre d'un seul flot de conception complet. La manipulation d'outils et de composants dans un flot complet de conception est un travail fastidieux, source d'erreurs, et coûteux en terme de temps de conception. Vu la pression du temps de mise sur le marché, un environnement ouvert à l'intégration d'outils et de composants logiciels/matériels est devenue cruciale. La contribution de cette thèse concerne la construction d'un environnement de conception ouvert autour d'un format intermédiaire. Cet environnement permet l'intégration d'outils selon un modèle bien défini. Il permet aussi l'intégration de composants logiciels/matériels selon un flot générique et des techniques de composition. Les concepts proposés ont été validés sur deux études de cas différentes : l'intégration de l'outil VCC de Cadence et l'intégration d'un IP de communication décrit à un haut niveau d'abstraction dans le flot de conception ROSES.

Available in PDF, EPUB and Kindle. Book excerpt: Ultra Wide Band Technology (UWB) has reached a level of maturity that allows us to offer wireless links with either high or low data rates. These wireless links are frequently associated with a location capability for which ultimate accuracy varies with the inverse of the frequency bandwidth. Using time or frequency domain waveforms, they are currently the subject of international standards facilitating their commercial implementation. Drawing up a complete state of the art, Ultra Wide Band Antennas is aimed at students, engineers and researchers and presents a summary of internationally recognized studies.

Download or read book Anthropology Of China The China As Ethnographic And Theoretical Critique written by Stephan Feuchtwang and published by World Scientific Publishing Company. This book was released on 2016-07-13 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Putting China into the context of general anthropology offers novel insights into its history, culture and society. Studies in the anthropology of China need to look outwards, to other anthropological areas, while at the same time, anthropologists specialised elsewhere cannot afford to ignore contributions from China. This book introduces a number of key themes and in each case describes how the anthropology and ethnography of China relates to the surrounding theories and issues. The themes chosen include the anthropology of intimacy, of morality, of food and of feasting, as well as the anthropology of civilisation, modernity and the state.The Anthropology of China covers both long historical perspectives and ethnographies of the twenty-first century. For the first time, ethnographic perspectives on China are contextualised in comparison with general anthropological debates. Readers are invited to engage in and rethink China's place within the wider world, making it perfect for professional researchers and teachers of anthropology and Chinese history and society, and for advanced undergraduate and graduate study.

Download or read book An Historical Geography of France written by Xavier de Planhol and published by Cambridge University Press. This book was released on 1994-03-17 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this 1994 book, Xavier de Planhol and Paul Claval, two of France's leading scholars in the field, trace the historical geography of their country from its roots in the Roman province of Gaul to the 1990s. They demonstrate how, for centuries, France was little more than an ideological concept, despite its natural physical boundaries and long territorial history. They examine the relatively late development of a more complex territorial geography, involving political, religious, cultural, agricultural and industrial unities and diversities. The conclusion reached is that only in the twentieth century had France achieved a profound territorial unity and only now are the fragmentations of the past being overwritten.
Download or read book Routledge International Handbook of Ignorance Studies written by Matthias Gross and published by Routledge. This book was released on 2015-05-15 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once treated as the absence of knowledge, ignorance today has become a highly influential topic in its own right, commanding growing attention across the natural and social sciences where a wide range of scholars have begun to explore the social life and political issues involved in the distribution and strategic use of not knowing. The field is growing fast and this handbook reflects this interdisciplinary field of study by drawing contributions from economics, sociology, history, philosophy, cultural studies, anthropology, feminist studies, and related fields in order to serve as a seminal guide to the political, legal and social uses of ignorance in social and political life.

Download or read book Signal Processing for Communications written by Paolo Prandoni and published by Collection Savoir suisse. This book was released on 2008-06-17 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a novel, less classical approach to the subject, the authors have written a book with the conviction that signal processing should be taught to be fun. The treatment is therefore less focused on the mathematics and more on the conceptual aspects, the idea being to allow the readers to think about the subject at a higher conceptual level, thus building the foundations for more advanced topics. The book remains an engineering text, with the goal of helping students solve real-world problems. In this vein, the last chapter pulls together the individual topics as discussed throughout the book into an in-depth look at the development of an end-to-end communication system, namely, a modem for communicating digital information over an analog channel.
Download or read book Xenakis written by James Harley and published by Routledge. This book was released on 2004-08-02 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Xenakis: His Life in Music is a full-length study of the influential contemporary composer Iannis Xenakis. Following the trajectory of Xenakis’s compositional development, James Harley, who studied with Xenakis, presents the works together with clear explanations of the technical and conceptual innovations that shaped them. Harley examines the relationship between the composer and two early influences: Messiaen and Le Corbusier. Particular attention is paid to analyzing works which were vital to the composer’s creative development, from early, unpublished works to the breakthrough pieces Metastasis and Pithoprakta, through the oft-discussed decade of formalization and the evolving styles of the succeeding three decades.
