Design of Embedded Storage Device Based on FPGA and NAND Flash

A small size embedded storage system based on FPGA and NAND Flash is designed for special data storage requirements in size under harsh working conditions. The system selects FPGA as the control core,NAND flash as the storage medium,and LVDS interface for data storages and replay. Communicates with computers are performed via gigabit network,and data are managed as files with data integrity guaranteed by bad-block management and ECC technology. The experimental results show that the system has the characteristics of high bandwidth and small size,is capable of real-time storage,replay,loading,unloading and management,and can work steadily in the harsh environment.
