摘要
根据航空电子综合系统的特点,对FC标准簇进行简化,设计了先锋交换网的通信协议(FC-Pio(Fibre Channel-Pioneer Net)协议)。重点介绍其在网卡(NIC)中的实现。由于简化了通信协议,软硬件的合理分工,使全部控制电路集成在一片FPGA之中,用双面PCB板实现。采用FC-Pio精简协议,也有效地降低了软件通信开销,提高了数据通信效率。
According to the special requirements of Avionics Integrated System （AIS）, the Standard Protocol of Fiber Channel has been simplified to be a new protocol, FC-Pio （Fiber Channel-Pioneer Net）. The implementation of the new protocol in Net Interface Card （NIC） is described specifically. Due to the simplification of FC-Pio and the reasonable assignment between the hardware and the software, the whole circuit of control is integrated in only one FPGA chip, just with a double-faced PCB board. With the FC-Pio Protocol, the software communication overhead is also greatly reduced. As a result, the high performance/cost ratio is achieved.
