摘　　要：为解决大数据量传输系统中传输速率低、带宽小、可靠性差的问题,提出一种基于SRIO协议的FPGA间大量数据高速传输的设计方案。设计使用FPGA内嵌SRIO IP核对传输数据进行发送、解析和接收;使用FPGA内部GTP高速串行收发器作为物理层传输基础;利用光电转换模块实现光、电信号的转换,以完成数据远距离传输。通过测试验证本设计数据传输准确可靠,传输速率可达280 MB/s,且本方案已成功应用于遥测系统存储器地面测试台项目,可实现两FPGA设备间大量数据高速可靠传输。In order to solve the problems of low transmission rate,small bandwidth and poor reliability in large data transmission system,this paper proposes a design scheme of high speed data transmission between FPGAs based on SRIO protocol.The design uses SRIO IP embedded in FPGA to check the transmission data for sending,parsing and receiving;The FPGA internal GTP high-speed serial transceiver is used as the physical layer transmission basis.Photoelectric conversion module is used to convert optical and electrical signals to complete data long-distance transmission.The data transmission rate can reach 280 MB/s,and the scheme has been successfully applied to the telemetry system memory ground test platform project,which can realize high-speed and reliable data transmission between two FPGA devices.
