Developing streaming applications on heterogenous multi-processor architectures like the Cell is difficult. Currently, application developers need to know about hardware details to deal with issues like scheduling, memory management and communication/synchronization. Worse, with multiple alternatives for communication available, developers spend significant… (More)
Core specialization is currently one of the most promising ways for designing power-efficient multicore chips. However, approaching the theoretical peak performance of such heterogeneous multicore architectures with specialized accelerators, is a complex issue. While substantial effort has been devoted to efficiently offloading parts of the computation,… (More)
Programming multimedia applications for System-on-Chip (SoC) ar-chitectures is difficult because streaming communication, user event handling, re-configuration, and parallelism have to be dealt with. We present Hinch, a runtime system for multimedia applications, that efficiently exploits parallelism by running the application in a dataflow style. The… (More)
Efficient programming of multimedia streaming applications for Consumer Electronics (CE) devices is not trivial. As a solution for this problem, we present SP@CE, a novel programming model designed to balance the specific requirements of CE streaming applications with the simplicity and efficiency of the Series-Parallel Contention (SPC) programming model.… (More)
Consumer electronics applications are becoming increasingly complex because of increased functionality requirements , such as watching multiple compressed video streams on a single screen. We address this complexity by allowing a programmer to specify the application in terms of independent components. Components interact using streaming communication and… (More)
