Flexible signal processing on programmable platforms are increasingly important for consumer electronic applications. Scalable video algorithms (SVAs) using the novel principle of priority processing guarantee real-time performance on programmable platforms, even with limited resources. Dynamic resource allocation is required to maximize the overall output quality of independent, competing priority processing algorithms that are executed on a shared platform. In this paper we describe the mapping of a priority processing application on the Cell/B.E. platform. We compare the performance of different implementations for dynamic-resource-allocation mechanisms, and show that priority processing achieves real-time performance
