摘　　要：介绍了一种基于可编程片上系统(SOPC)的光纤通道(FC)网络接口卡(NIC)的总体设计方案;该方案采用了NiosⅡ软核处理器的嵌入式技术;并将NiosⅡ软核处理器和网络接口卡的控制逻辑集成在一块FPGA芯片中;且数据的发送和接收采用流水技术。测试结果表明该设计方案达到了设计要求,通信性能稳定可靠;该方案极大地提高了系统的集成度和稳定性,使NIC的通信协议得到了极大的简化;由于能够灵活的自定义外设,因此也能够加快NIC开发速度。The whole design scheme of a kind of fiber channel network interface card based on system on programmable chip （SOPC） is discussed in the thesis. The embedded technology Nios Ⅱ soft-core processor is used in this scheme, the Nios Ⅱ soft-core processor and the control logic of network interface card are integrated on one FPGA; Technology of streamline is used in the communication data＇s sending and receiving. The testing data indicate that the scheme reaches to the design need, the performance of communication is stable and dependable. The scheme can enhance the integration of the system greatly, and predigest the protocol of the NIC; It can define external equipment by yourself, so it expedites the speed of NIC＇ s exploitation.
