NoC based virtualized accelerators as cloud services

2016

National audience; Hardware accelerators(HwAcc) provide good performance in computation intensive applications. Integrating hardware accelerators in a cloud environment is the optimal way to improve the quality of service. However, mapping all possible application statically into the reconfigurable fabric of the FPGA is rather impractical and prohibitively expensive in terms of resource and power consumption. This problem can be alleviated via time multiplexing the access to the underlying hardware resources, FPGA, by designing dynamically reconfigurable accelerators in the cloud. Similarly, the connection and communication between the accelerators and the reconfigurable control will not be…

Sharing spatial data with a 3D component as a collaborative and dissemination tool for archaeology: conceptual challenges and technical issues

2018

International audience; Due to INSPIRE directive, various spatial data infrastructure (SDI) were developed to support research activities. In practice, these toolsremain underexploited by researcher for many reasons. First, their use is time-consuming and researchers usually consider that they provide noimmediate benefits. Second, their use is often complex and needs a substantial investment for researchers who have a limited expertise in spatial data. Finally, often based on 2D GIS environment, they do not provide an adequate tool for collaborative research in archaeology. From this experience, an interdisciplinary team designed and developed an SDI based on GeOrchestra, synchronized with …

Extensions matérielles pour processeurs embarqués de traitement d'images.

2007

12p; Le marché des imageurs embarqués est entré dans une ère nouvelle avec l'avènement des téléphones portables munis d'appareils photographiques et de caméras. Il est attendu qu'à l'horizon 2009, leur nombre dépassera celui de l'ensemble des appareils photos vendus depuis l'invention de la photographie, et ce qu'ils soient numériques ou non. Le marché des imageurs électroniques embarqués est donc un secteur porteur, notamment au travers de la téléphonie et de la visiophonie mobile. Les applications ne sont plus limitées à la simple photographie ou la transmission de vidéo ; les lecteurs de codes matrices, la reconnaissance de visages, la biométrie, ou la vision 3D sont des exemples parmi l…

PROCEDE DE PRE-DISTORSION NUMERIQUE D’UN SIGNAL ET REPETEUR DE TELECOMMUNICATION INTEGRANT UN FILTRE A REPONSE IMPULSIONNELLE FINIE POUR METTRE EN OE…

2013

L'invention concerne un procédé de pré-distorsion numérique d'un signal de télécommunication traité dans un circuit électronique 100 intégrant un filtre à réponse impulsionnelle finie 321. Ce procédé consiste successivement: - à identifier, à la sortie du circuit 100, les paramètres de distorsions de phase et/ou d'amplitude du signal en fonction de la fréquence, - à partir des susdits paramètres de distorsions relevés, à générer, par un algorithme basé sur une interpolation, des coefficients permettant d'effectuer dans ledit filtre 321, des prédistorsions du signal numérique destinées à engendrer une précorrection des susdites distorsions, - à transférer lesdits coefficients de pré-distorsi…
