摘要
针对Philips公司的多媒体处理芯片PNX1500硬件结构特点,设计了适应实时信号处理的高性能H.264编码器架构。采用了先进的快速变换和搜索算法,完成了对代码的逐步优化和调试。实验结果表明,该编码器能实现对各种运动幅度视频数据的快速编码,满足不同运动级别视频信号的实时处理。
Based on the architecture of multimedia chip PNX1500 invented by Philips Semiconductor, a design of a H.264 encoder with high performance for real time signal processing is presented in this paper, which chooses the advanced integer translation and searching algorithm, accomplishes the optimization and debugging for codes. The result of experiment indicates that the encoder can encode all kinds of video data rapidly and can fulfil the real time processing for all kinds of video signals.
