Méthodologie de conception d'architectures reconfigurables dynamiquement, application au transcodage vidéo

Abstract : Despite clear benefits in terms of fexibility and surface efficiency, dynamic reconfiguration of FPGAs is still finding it hard to break through into massive industrial project. One of the main reasons is the lack of means and methods for evaluation of reconfigurable architectures. Worse, main FPGA vendors do not provide official tools allowing developers to easily determine an optimal scheduling reconfiguration for a specific architecture. Within this framework, the proposed research work described in this thesis proposes a methodology for modeling dynamically reconfigurable architectures based on SystemC. The proposed methodology allows designers to save significant time during the design phases of an application specific reconfigurable architecture by providing an initial estimate of performance and resources needed for its development. It also allows development and validation of scheduling reconfiguration scenarios, while respecting real-time constraints associated with the given application. To validate our methodology on a real application, video transcoding IP have been developed and tested. This application consists in the realization of a H.264/MPEG-2 transcoder made self-adaptable through the use of dynamic reconfiguration. This work was conducted as a part of the ARDMAHN project sponsored by the National Research Agency (Agence Nationale de Recheche) with the reference number ANR-09-SEGI-001
