摘　　要：针对某嵌入式项目需要实现基于龙芯1B处理器的计算和以太网通信功能。文中采用龙心1B处理器集成两路千兆以太网,基于天脉1嵌入式实时操作系统,设计实现了龙芯1B处理器平台下双网卡以太网驱动。网卡驱动可同时支持基于以太网的调试和通信功能;也可通过一路网卡进行调试,同时使用另外一路网卡进行通信。实验结果证明,所设计实现的以太网驱动功能正确,在天脉1嵌入式操作系统下,能正确实现对龙芯1B处理器两路千兆网卡的控制;网卡驱动能正确,可靠地工作,以太网通信功能正常。A driver for the double Gigabit Ethemet cards integrated in the Loongson 1 B processor on the Tianmai embedded real-time operating system is designed and implemented. The driver supports not only simultaneous Ethernet-based debugging and communication but also one card for debugging and the other for communication. Experimental results show that the designed Ethernet driver functions correctly for the Loongson 1 B double Gigabit Ethernet cards on the Tianmai embedded operating system, realizing reliable operation and normal Ethernet communication functions.
