| With high bandwidth,multi-media,low latency,open interconnection and other advantages,fibre channel is widely used in the commercial field and expected to replace MIL-STD-1553,which has been widely used.Fibre channel will become the first choice of future avionics system and apply to the field of space eventually to build into a new generation of aerospace electronic network.So,the main task is developing the core of Fibre Channel processing chip independently nowadays to be used in the field of aerospace.In this paper,FC-AE protocol is analyzed in detail from the aspects of Fibre Channel layer structure,topology,service,building block and protocol,and the FC-0 physical layer,FC-1 coding layer and FC-2 protocol layer are focus on analyse and study.In addition,data transfer protocol,primitive sequence protocol and N_Port login and logout protocol of FC-2 are illustrated in detail.According to Class III service of Fibre Channel Protocol,a fibre channel protocol processing FPGA based on Virtex-6 is designed to complete: FC-2 transmission and reception,port state machine and flow control;FC-1 8B/10 B encoding and decoding;FC-0 parallel and serial conversion and other functions.In addition,a set of data transmission and reception systems based on fibre channel is established,and the correctness and performance of this system is verified by function simulation and hardware debugging.In addition,the shortcomings are summarized.This system has strong engineering significance for realization of FC-AE protocol chip. |
