| 摘 要： | DSP处理器一般不带网络接口,设计了基于TMS320F2812连接高性能网络控制器AX88796组成的带网络接口的开发系统.该系统采用了AX88796的底层驱动程序,裁减TCP/IP协议栈并将其移植到DSP开发系统上.重点解决了驱动初始化,网卡的接收缓冲环管理和TCP/IP协议校验和计算等问题,实现了F2812驱动AX88796,通过TCP/IP协议接入互联网.

| Abstract: | Usually, there is no network interface in DSP processor. A developing system with network interface which connected high performance network controller AX88796 with TMS320F2812 is designed. A driving program of AX88796 is adopted by the DSP developing system, and the TCP/IP protocol is cut out to transplant to it. This paper mainly resolves the driving initiation, receiving ring buffer management of the network card, and the check sum of TCP/IP etc. F2812 connected into internet by driving AX88796 and throng TCP/IP is realized. |
