To handle the increasing storage needs of data-intensive applications in the era of big data,we design and implement a high-performance flash memory-based solid state drive (SSD)prototype system.The FPGA-based SSD consists of flash memory chips,and communicates with the host through PCIe.PCIe interface module,DRAM controller,flash translation layer and flash memory controllers are implemented in the FPGA.In this paper,the design of PCIe interface,flash translation layer and synchro-nous flash controller are described in detail.Experiment results show that the SSD prototype system can meet high-bandwidth and high-throughput storage needs,providing 2.6 GB/s write bandwidth,2.93 GB/s read bandwidth and 300 000 read/write IOPS.
