A methodology to implement real-time applications on reconfigurable circuits

Special Issue Engineering of Configurable SystemsInternational audienceThis paper presents an extension of our AAA rapid prototyping methodology for the optimized implementation ofreal-time applications onto reconfigurable circuits. This extension is based on an unified model of factorized datadependence graphs as well to specify the application algorihtm, as to deduce the possible implementations ontoreconfigurable hardware, in terms of graphs transformations. This transformation flow has been implemented inSynDEx, a system level CAD software tool

Implantation optimisée sur circuit dédié d'algorithmes spécifiés sous la forme d'un Graphe Factorisé de Dépendances de Données : application aux traitements d'images

On présente un flot de prototypage rapide pour l'implantation optimisée d'applications temps réel sur des circuits dédiés. Ce flot est basée sur un modèle unifié de graphes factorisés de dépendances de données autant pour spécifier l'algorithme que pour en déduire les implantaions possibles en termes de transformations de graphes

SysCellC: SystemC on Cell

International audienceHigh performance computing with low cost machines becomes a reality. As an example, the Sony playstation3 gaming console offers performances up to 150 gflops for a machine's retail price of $400. Unfortunately, higher performances are achieved when the programmer exploits the architectural specificities of its Cell processor: he has to focus on inter-processor communications, task allocations among the processors, task scheduling, external memory prefetching, and synchronization. In this paper, we propose and evaluate a compile flow that automates the transformation of a program expressed with the high level system design language SystemC used as a programming model, to its implementation on the Cell processor. SystemC constructs and scheduler are directly mapped to the Cell API, preserving their semantic. Inter-processor and external memory communications are abstracted by means of SystemC channels. We illustrate the approach on two case studies implemented on a Sony Playstation 3
