摘　　要：随着信息技术的发展,数据存储对带宽和容量的要求越来越高。针对此需求,设计了一种基于SW831处理器+FPGA+非易失性存储器快速通道(NVME)的存储系统。系统前端使用FPGA采集数据,为了保证数据不丢失,FPGA先将数据缓存到内存,由于缓存空间有限,需要及时地将缓存数据写入到存储盘中。基于此目的,提出了一种基于SW831处理器的数据管理方法,通过无容错的条带化磁盘阵列(RAID0)方式管理NVME存储阵列,应用链表直接管理NVME盘的存储块,通过SW831的控制,将FPGA缓存的数据直接搬移到NVME存储盘中,有效提高了数据存储效率,经实际测试,在系统总容量为12 TB的情况下,平均存储速率可达6.4 GB/s。另外,通过管理软件的配合,用户可以以文件的方式管理、访问数据,使用较为方便。With the development of information technology,data storage requires higher and higher bandwidth and capacity.To meet this demand,a storage system based on SW831 processor+FPGA+non-volatile memory express(NVME)is designed.The front-end of the system uses FPGA to collect data,and in order to ensure that the data is not lost,the FPGA caches the data into the memory first.The caching space is limited,so the cached data should be written to the storage disk in a timely manner.Based on this purpose,a data management method based on SW831 processor is proposed,which manages the NVME disk array using striped disk array without fault tolerance(RAID0)method and applies a linked list to manage the blocks of the NVME disk directly,and the data cached by the FPGA can be moved to the NVME disk directly through the control of SW831,which effectively improves the efficiency of data storage.Through practical test,with a total system capacity of 12 TB,the average storage rate is up to 6.4 GB/s.In addition,the user can manage and access the data in the form of files with management software,and it is user-friendly.
