摘　　要：为了满足遥测系统大容量数据高速可靠传输的需求,提出了一种基于FPGA和Serial RapidIO(SRIO)的数据传输链路优化设计,传输链路为4x模式,传输速率为2.5 Gb/s。针对测试过程中链路异常被训练成1x模式而造成数据传输异常的现象进行深入分析,采用上电复位和软件复位相结合的方法对传输链路进行优化,经测试验证,优化后的链路数据传输稳定,1路SRIO数据传输速率可达585 MB/s,且无丢帧、误码现象。该设计已成功应用于遥测系统项目,实现高速数据稳定传输。In order to meet the demand for high speed and reliable transmission of large-capacity data in telemetry system,a data transmission link optimization design based on FPGA and Serial RapidIO(SRIO)is proposed,the transmission link is in 4x mode,and the transmission rate is 2.5 Gb/s.In-depth analysis is carried out for the phenomenon that the link is abnormally trained to be in 1x mode during the testing process,which results in the data transmission abnormality,and a combination of power-on reset and software reset is adopted to optimize the transmission link.In-depth analysis of the phenomenon of abnormal data transmission caused by the link abnormally trained to 1x mode during the test,the transmission link is optimized by the combination of power-on reset and software reset,and the optimized link is verified to be stable in data transmission,and the data transmission rate of 1-channel SRIO can reach 585 MB/s without frame loss and BER phenomenon.The design has been successfully applied in telemetry system projects to achieve high-speed data stable transmission.
