【摘要】 文章提出一种基于SOC架构的嵌入式网络视频服务器的设计思路,从硬件结构、软件框架等方面介绍了系统的实现方法.采用智源公司的GM8120作为系统主控芯片,该芯片的最大优点在于除功能强大的FA526 RISC 32位CPU外,整合了MPEG4编解码器,无需设计音视频压缩编码模块,简化了系统组成.软件平台采用可移植、裁减和实时多任务特性的Linux操作系统,用于处理复杂的网络传输协议,具有良好的稳定性和可靠性.更多还原

【Abstract】 This paper introduces the design of embedded network video server based on SOC architecture, and its implementation in terms of hardware structure and software frame,which uses GM8120 as the mastership chip,integrating the encoding and decoding of MPEG4 in addition to 32 bit CPU of FA526 RISC. Therefore,there’s no need to design the audio and video module,thus simplifying the system.Software platform adopts the Linux operating system,which is transportable,cuttable and real-time multi-tasking,to deal with complex network transfer protocol,which ensures the stability and reliability.更多还原
