摘要

提出了一种在多核处理器上设计并行H.264视频编码器的高度模块化和可配置平台。从H.264/AVC参考软件出发，进行了初步优化并开发了新的数据结构，以支持编码器的并行化，并赋予开发的平台灵活，用户可配置和高度可扩展的特性，涉及目标具体化中使用的可用内核数量。在使用平台的不同实例进行仔细评估后，实验结果表明，通过同时利用该平台提供的几种不同的并行化模型，可以获得与实现帧率相关的显着且接近线性的加速。

p264: open platform for designing parallel H.264/AVC video encoders on multi-core systems

A highly modular and configurable platform for designing parallel H.264 video encoders on multi-core processors is presented. Departing from the H.264/AVC reference software, preliminary optimizations were conducted and new data structures were developed, in order to support the encoder's parallelization and to confer the developed platform with a flexible, user configurable and highly scalable characteristics in what concerns the number of available cores to be used in the target concretization. After a careful assessment using different instantiations of the platform, the experimental results have shown that significant and close to linear speedups in what concerns the achieved frame-rate can be obtained, by simultaneously exploiting the several different parallelization models that are made available by this platform.
