The invention provides a method for realizing FC communication rate detection based on an FPGA, and the method mainly comprises an FC photoelectric conversion unit and an FPGA rate detection unit. The FC photoelectric conversion unit realizes optical signal detection and FC communication signal light-to-electricity medium conversion, and the FPGA rate detection unit is mainly realized through logic in an FPGA chip; a receiving line rate frequency division value of a data port is configured through a dynamic configurable interface to realize conversion between a high rate, a medium rate and a low rate, and detection of a current communication rate is realized by judging a matching condition of a special code pattern K28.5 corresponding to 8b / 10b conversion. The method provided by the invention is simple in implementation form, and the FC signal communication rate can be detected in real time only through a configurable phase-locked loop and a clock frequency dividing circuit in the FPGA without an external frequency sweeping circuit; the method can be used for equipment for detecting the communication rate of the FC network channel node, and has a wide application prospect in airborne FC bus communication monitoring and testing equipment.
Description
technical field [0001] The invention relates to the technical field of high-speed data communication, in particular to a method for realizing FC communication rate detection based on FPGA. Background technique [0002] With its high bandwidth, low latency, and high reliability, Fiber Channel technology is widely used in the field of distributed communication and network data transmission. The protocol standard FC-AE-ASM for avionics has also been widely used in the new generation of airborne In the bus interconnection scheme. Currently, the commonly used communication rates for FC-AE communication include 1.0625G, 2.125G, and 4.25Gbps. The FC communication rate also needs to be adjusted according to the difference in the usage environment and the amount of transmitted data. Therefore, we propose a method to detect FC communication speed based on FPGA. Contents of the invention [0003] The purpose of the present invention is to provide a method for detecting the FC commu...
