摘要
应用以太网硬件协议栈芯片技术,设计并实现了具有网络数据高速传输功能的DSP嵌入式系统。以太网选用专用芯片W5100,该芯片适用于嵌入式系统,并具有Internet协议。通过配置系统网络信息来实现整套系统的TCP和UDP连接,同时以Server或Client模式进行数据传输。以基于W5100的DSP嵌入式数据采集系统为例,通过合理编写程序和配置各寄存器,验证表明,系统可以通过以太网成功传输数据。
The DSP embedded system offering high speed transmission function for network data is designed and implemented by adopting the technology of Ethernet hardware protocol stack chip. The dedicated chip WSI00 is selected for Ethernet, that chip is suitable for using in embedded system and possess Internet protocol. Through configuring system network information, the TCP and UDP connection in whole system can be realized for data transmission in Server or Client mode. With DSP embedded data acquisition system based on WS100 as example, through reasonable programming and configuring each register, the verification shows that successful data transmission through Ethemet can be conducted for the system.
