A high-speed data unloading scheme based on XC7K325 FPGA chip is designed.GTX channel of user-defined protocol is used to receive high-capacity data on data acquisition equipment,and support data flow control through user-defined flow control protocol.The received data and status information are sent to the data analysis system through PCIE interface.In the opposite direction,the commands and data of the data analysis system are transmitted to the data acquisition equipment.Through the actual measurement,the unloading rate can reach more than 850 MB,which has high application value.
