Prototypage Rapide et Génération de Code pour DSP Multi-Coeurs Appliqués à la Couche Physique des Stations de Base 3GPP LTE
TLDR
Un distributeur adaptatif capable of faire des choix en temps reel sur the base of temps d'execution predits sur the differents cœurs contenus dans un eNodeB is presented.Abstract:
Le standard 3GPP LTE (Long Term Evolution) est un nouveau standard de telecommunication terrestre dont la couche physique des stations de base, appelees eNodeB, est particulierement couteuse. Les processeurs de traitement du signal (DSP) sont largement employes dans les stations de base pour calculer les algorithmes de la couche physique. Les DSPs de derniere generation sont des systemes complexes et heterogenes. Il n'existe pas actuellement de solution ideale pour distribuer les parties d'une application comme le LTE sur les differents cœurs contenus dans un eNodeB. Dans cette these, nous presentons une methode de travail pour le prototypage rapide et la generation de code automatique. Certains algorithmes de la couche physique du LTE etant trop variables pour une distribution hors-ligne, nous presentons un distributeur adaptatif capable de faire des choix en temps reel sur la base de temps d'execution predits.read more

Optimized dynamic compilation of dataflow representations for multimedia applications
TL;DR: Dataflow representations from the upcoming MPEG Reconfigurable Media Coding (RMC) standard are used to supply the decoding information to adaptive decoders and two optimizations based on dataflow representations and dynamic compilation are proposed that enhance flexibility and performance of multimedia applications.

Memory bounds for the distributed execution of a hierarchical Synchronous Data-Flow graph
TL;DR: An application analysis technique to define the boundary of shared memory requirements of Multiprocessor System-on-Chip (MPSoC) in early stages of development is presented and a heuristic approach is proposed to provide a near-optimal solution of the MWC problem.
