摘　　要：针对传统基于嵌入式平台或DSP构建的H.264编码系统编码性能差,可扩展性低的缺点,提出基于FPGA开发平台设计的H.264视频编码SoC系统。本文主要介绍了其中最重要的熵编码模块。实验结果表明,与传统的基于嵌入式处理器的编码系统相比,基于FPGA开发平台的编码系统可以实现视频采集、实时编码和存储,编码后视频播放流畅,无数据丢失或数据出错等情况,系统各项功能运行良好,并且系统具有很好的可移植性与可配置性,占用资源少、速度快、具有广泛的应用前景。The H.264 encoding system based on the traditional embedded developing platform has many disadvantages such as has low encoding performance,low e xtensibility and so on.In order to solve the problems,the H.264 video encoding SoC system based on FPGA development platform design is proposed.The most important module is the entropy encoding module in the system.The experiment re- sults indicate that, the encoding system can realize the video collecting, encoding, and storage comparing with the H.264 encoding system based on the traditional embedded developing platform.After encoding, the video plays smoothly, without data missing or errors.Further- more,the system has good portability and configurability,therefore it has a broad application prospects.
