[Abstract]:With the radar testing, remote sensing satellite, network system communication and other areas of system data bandwidth increasing, the corresponding data transmission system requirements are higher and higher, only with the ability of high-speed data acquisition and transmission, can realize the huge data flow interaction. In order to meet the demand of high speed data acquisition ability in related fields, this paper has carried out the research of 10Gbps level high speed data acquisition and transmission system related technology, this paper mainly studies the high speed optical fiber data acquisition and transmission system correlation technology, Including optical fiber communication theory research, computer communication bus protocol analysis, high-speed large capacity buffer circuit design, and test system integration solution analysis. The specific work includes the following aspects: (1) using SFP optical module to design high speed optical fiber data transceiver hardware circuit with 10Gbps level communication capability, and realizing 10Gbps class optical fiber communication controller based on Aurora protocol through Aurora IP core of Xilinx company and internal logic of FPGA. 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.
