Simulation de haut niveau de systèmes d'exploitations distribués pour l'exploration matérielle et logicielle d'architectures multi-noeuds hétérogènes

Abstract : Designing an embedded system implies to look for the right algorithm/architecture compromise depending on the real-time constraints. For MPSoC an especially with reconfigurable devices which enable to modify the running executing support, a validation by a preliminar evaluation of the variable behaviors of a reactive system becomes necessary. This could be done by a high level simulation allowing to explore, early in the design flow, the architectural design space, hardware and software, especially the RTOS. The platform manager point of view is used to explore the systems reactions to the partitioning choices and also the influence of the various algorithms and the impact of implementations of the operating system's services refined in hardware or software. For that, a SystemC model composed of modular OS services allow to jointly and functionally simulate hardware, software tasks and the operating system, distributed on heterogeneous communicating execution nodes. To evaluate the perfect real-time reconfigurable architecture of a dynamical robot vision application, we explored its partitioning and the useful OS services accordingly. This model has been integrated in a big simulator of an heterogeneous chip designed to provide a Tera operations per second power.
