Real-time priority processing on the Cell platform

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.
