摘要
Xscale PXA27x是Intel公司新近推出的一款高性能数字多媒体处理器,具有Wireless MMX协处理单元,为高效实现H.264视频编码算法提供了有力的保证。文章提出了一种优化策略,较好地实现了PDA或3G手机中的实时视频编码。在HP2490实验平台上,码率为64kbps的QCIF的编码速率为31ms/帧。
Xscale PXA27x is a high performance digital multi-media processor with Wireless MMX unit put out recently by Intel Corp. It could help realize video coding algorithm efficiently. An optimization strategy is proposed to realize the real-time video Encoding. Running on the HP 2490 test platform, the encoding speed reaches 3 lms per frame for QCIF foreman sequences with 64kbps.
