| Abstract | Newer video compression standards provide high video quality and greater compression efficiency, compared to their predecessors. Their increased complexity can be outbalanced, by leveraging all the levels of available parallelism, taskand data-level, using available off-theshelf hardware, such as the current generation‟s chip multiprocessors. As we move to more cores, though, scalability issues arise and need to be tackled in order to take advantage of the abundant computational power. In this paper we evaluate a previously implemented parallel version of the AVS video decoder on the experimental 32-core Intel Manycore Testing Lab. We examine this previous version‟s performance bottlenecks and scalability issues and introduce a distributed queue implementation as the proposed solution. Finally, we provide insight on separate optimizations regarding inter macroblocks, and investigate performance variations and tradeoffs, when combined with a distributed queue scheme. |
