随着以太网络技术和数字信号处理技术的飞速发展,如何使嵌入式处理器具备网络通讯的功能成为目前研究的新领域。结合以DSP TMS320C6713为主处理器的SEED-DEC6713嵌入式控制板和新型10/100M自适应以太网控制器LAN9218I,主要讨论了如何扩展SEED-DEC6713的网络通讯模块,如何编写网卡的驱动程序,以及如何在嵌入式实时操作系统μC/OS-II上移植TCP/IP协议栈LwIP的问题。经过测试将所开发的这套硬件系统应用于网络音频数据的监听,收到了实效。
With the rapid development of Ethernet technology and digital signal processing technology, how to make the embedded processor have the function of network communication has become a new field of research at present. Combined with DSP TMS320C6713-based SEED-DEC6713 embedded controller and the new 10 / 100M adaptive Ethernet controller LAN9218I, mainly discussed how to expand SEED-DEC6713 network communication module, how to write the network card driver, and How to transplant TCP / IP protocol stack LwIP on embedded real-time operating system μC / OS-II. After testing the hardware system developed by the application of network audio data monitoring, has received real results.
