【Abstract】 This paper designed a high-speed data acquisition and storage system,used NAND FLASH as the storage device.The organizational structure and storage characteristics of the NAND FLASH were introduced. The pipeline technology was applied based on the study of the principle of the NAND FLASH,which made the high speed data storage achieved. The bad block management program was implemented that can make the reliability of data storage greatly improved. This system has been applied on vehicle,and is proved accurate and reliable. It is very important to the study of the vehicles’ s automatic transmission control system.更多还原
