This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: De nombreuses techniques de codage de canal sont spécifiées dans les nouvelles normes de communications numériques, chacune adaptée à des besoins applicatifs spécifiques (taille de trame, type de canal de transmission, rapport signal-à-bruit, bande-passante, etc.). Si l'on considère les applications naissantes multi-mode et multi-standard, ainsi que l'intérêt croissant pour la radio logicielle et la radio cognitive, la combinaison de plusieurs techniques de correction d'erreur devient incontournable. Néanmoins, des solutions optimales en termes de performance, de consommation d'énergie et de surface sont encore à inventer et ne doivent pas être négligées au profit de la flexibilité. Dans ce contexte, ce travail de thèse a exploré le modèle d'architecture multi-ASIP dans le but d¿unifier l'approche orientée sur la flexibilité et celle orientée sur l'optimalité dans la conception de décodeurs de canal flexibles. En considérant principalement les applications exigeantes de décodage itératif des turbocodes et des codes LDPC, des architectures multi-ASIP de décodeurs de canal sont proposées ciblant une grande flexibilité combinée à une haute efficacité architecturale en termes de bits/cycle/iteration/mm2. Différentes solutions architecturales et différentes approches de conception sont explorées pour proposer trois contributions originales. La première contribution concerne la conception d'un décodeur LDPC/Turbo multi-ASIP extensible, flexible et haut débit. Plusieurs objectifs de conception sont atteints en termes d'extensibilité, de partage de ressources, et de vitesse de configuration. Le décodeur proposé, nommé DecASIP, supporte le décodage des codes LDPC et turbocodes spécifiés dans les normes WiFi, WiMAX et LTE. L'extensibilité apportée par l'approche multi-ASIP basée sur des réseaux sur puces (NoC) permet d'atteindre les besoins en haut débit des normes actuelles et futures. La deuxième contribution concerne la conception d'un ASIP paramétré pour le turbo-décodage (TDecASIP). L'objectif étant d'étudier l'efficacité maximale atteignable pour un turbo décodeur basé sur le concept ASIP en maximisant l'exploitation du parallélisme de sous-blocs. En outre, avec cette architecture nous avons démontré la possibilité de concevoir des coeurs de traitement paramétrables et dédiés à l'application en utilisant le flot de conception ASIP existant. La troisième contribution correspond à la conception d'un ASIP optimisé pour le décodage des codes LDPC (LDecASIP). Comme pour TDecASIP, l'objectif étant d'étudier l'efficacité maximale atteignable pour un décodeur de codes LDPC basé sur le concept ASIP en augmentant le degré de parallélisme et la bande passante des mémoires. Une quatrième contribution principale de cette thèse porte sur le prototypage matériel. Une plateforme de communication complète intégrant 4-DecASIP pour le décodage de canal a été prototypé sur une carte à base de circuits FPGA. À notre connaissance, c'est le premier prototype FPGA publié de décodeur de canal flexible supportant le décodage des turbocodes et des codes LDPC avec une architecture multi-ASIP intégrant des NoC. De plus, une intégration ASIC de ce décodeur a été réalisée par le CEA-LETI dans la puce MAG3D visant des applications de communications pour la 4G. Ces résultats démontrent le cycle de conception rapide et l'efficacité offerte par l'approche de conception basée sur le concept ASIP dans ce domaine d'application, permettant ainsi d'affiner les compromis de conception par rapport aux divers objectifs ciblés
