摘　　要：针对FPGA多应用任务中数据突发传输的丢包问题,文中提出了一种适用于FPGA流量管理的RFCF算法。在基于速率的流量管理策略基础上,接收端通过控制字符将剩余资源反馈至发送端。发送端根据资源余量采用不同数据优先级传输策略,保证在多应用任务下及时处理突发数据。在FPGA板卡中对该算法进行实现及验证,结果表明RFCF算法有效改善了FPGA在多应用任务场景下的数据传输能力。与基于速率的流量管理算法相比,文中所提方法的丢包率降低了14.9%。In view of the packet loss problem of data burst transmission in FPGA multi-application tasks,this study proposes a RFCF algorithm for FPGA traffic management.Based on the rate-based traffic management strategy,the receiver feeds back the remaining resources to the sender by controlling the characters.The sender adopts different data priority transmission strategies according to the resource margin,so as to ensure that the burst data can be processed in time under multi-application tasks.The algorithm is implemented and verified in FPGA board.The results show that the RFCF algorithm can effectively improve the data transmission capability of FPGA in multi-application task scenarios.Compared with the rate-based traffic management algorithm,the packet loss rate of the proposed method is reduced by 14.9%.
