Évaluation comparative de plates-formes reconfigurables et programmables pour les télécommunications de 3ème génération
- L'évolution des systèmes de radio-communications cellulaires se traduit par un accroissement important de la complexité des applications à implanter. En particulier, l'utilisation de la technologie WCDMA (Wideband Code-Division Multiple Access) dans les systèmes de troisième génération nécessite des capacités de calcul élevées. Dans cet article, les résultats de l'implantation d'un récepteur WCDMA au sein de différentes plates-formes programmables ou reconfigurables sont présentés. Les différentes solutions d'implantation sont comparées en termes de coût, de performances et d'efficacité énergétique. De plus, la méthodologie proposée pour obtenir la spécification en virgule fixe du récepteur est exposée

Securing a RISC-V architecture: A dynamic approach
International audienceThe SecureV (also known as SecV) project offers aninnovative, open-source hardware, secure, and high-performanceprocessor core based on the RISC-V ISA. The originality of theapproach lies in the integration of a complete solution to increasesecurity based on dynamic code transformation, covering 4 ofthe 5 NIST1 functions of cybersecurity via monitoring (identify,detect), obfuscation (protect), and dynamic adaptation (react)
