Run-Time Scheduling for Multimedia Applications on Dynamically Reconfigurable Systems

Current multimedia applications are characterized by highly dynamic and non-deterministic behavior as well as high-performance requirements. In addition, portable devices demand also low energy consumption. Potentially, Dynamically Reconfigurable Hardware resources (DRHW) present the ideal features to fulfill these requirements since they can be reconfigured at run-time to match the performance and energy consumption requirements. However, the lack of programming support for dynamic task placement as well as the large configuration overhead has prevented a broader use of DRHW resources on embedded system design. To cope with these two problems, we have adopted a DRHW model with specific support for task migration and inter-task communication. On top of it we have applied an energy-aware run-time scheduling technique capable of taking advantage of the DRHW flexibility. Finally, we have developed a set of modules that greatly reduces the reconfiguration overhead, making it affordable fo...
