一种基于FPGA高速存储设备的级联存储系统OA

In high-speed storage devices based on FPGA,the cascading capability between devices is crucial for the compatibility and scal-ability of the devices.Therefore,this paper designs a cascading storage system for high-speed storage devices based on FPGA,which in-tegrates the high bandwidth of FPGA-based high-speed storage devices and the flexible scalability of general storage devices.Experimen-tal results show that under the"one master and multiple slaves"management mode of global clock synchronization and token polling,this cascading storage system can maintain a storage bandwidth of 6.40 GB/s.In the continuous writing and replay tests of large-scale data,the data is stably written and there are no error codes in the verification,effectively achieving the transparent expansion of the storage system.
