摘要
Abstract
In allusion to the problems of slow data reading and low data stability in the current serial port and USB 2.0 methods for detecting bad blocks and implementing data reading,NAND FLASH is commonly used in the design of high-speed and high-capacity storage devices.A NAND FLASH data storage design based on the USB 3.0 bus is designed.FPGA is used as the logic control unit,the USB 3.0 chip CYUSB3014 is used as the communication bridge between FPGA and upper computer,and ECC data verification and error correction as well as bad block management for NAND FLASH are designed on FPGA software.Users can read,erase,and analyze data by means of the upper computer.The experimental results show that the designed system can transfer the data stored in NAND FLASH to the upper computer by means of the USB 3.0 interface,and the actual transmission speed can reach 39 MB/s.关键词
