摘　　要：针对传输视频流业务的应用需求,设计并实现了以达芬奇技术系列芯片DM3730处理器和以太网处理芯片W5300为组成核心的嵌入式视频传输系统。深入分析了基于W5300的以太网卡驱动程序设计方法,分别实现了W5300软/硬件协议栈在Linux环境下的移植,并通过实验以FTP传输方式测试了视频流业务的传输性能。实测表明该系统达到了2.6Mbps的传输速率,可以满足传输视频流业务的性能要求。For the requirements of video streaming transmission services, an embedded video transmission system is designed and implemented based on DM3730 DaVinci technology processors and Ethernet interface chip W5300. The design method of the driver for Ethernet interface card based on W5300 is analyzed. The transplants of both hardware and software protocol stack for W5300 are achieved in Linux OS environment. Moreover, by using FTP transmission experiments, the performance of video streaming transmission services is verified. It is shown that 2.6Mbps transmission rate can be achieved, which satisfied the system performance requirements.
