The standard system bus PCI-Express 2.1 communication protocol is studied, and the PCI-Express communication engine based on DMA data transmission mode is designed by using PCI-Express2.1IP core of Xilinx Company. In order to solve the problem of insufficient cache capacity in high speed data acquisition system, an extensible cache circuit with high speed capacity is designed. The maximum supporting capacity is extended to 8GB, the maximum working frequency is 1600MHz, and the buffer circuit controller is designed by using the internal logic of FPGA to realize data cache. The system testing platform is built, and the function of the system is verified by time-domain and frequency-domain analysis. The test results show that the high speed optical fiber data acquisition and transmission system designed in this paper can collect and transmit data at high speed. The maximum data transmission capacity of the system is up to 10Gbps. it meets the needs of high-speed data acquisition and transmission in most test fields and has strong practicability.
