介绍了一种采用数字信号处理器、CF 卡以及数据采集电路构建的大容量数据存储系统,并针对FAT 文件系统实际操作困难、访问效率不高等弱点,提出了CF卡中数据存储的一种新格式——简化FAT 格式。实践证明了,该格式操作简单、执行效率高、稳定可靠且可为Windows 操作系统所识别,适合大容量存储系统应用。 关键词: CF 卡; IDE 接口; 简化 FAT 格式 Abstract: The design of bulky data storing system based on Digital Signal Processor, Compact Flash card and data acquisition circuit is discussed firstly. Considering the deficiency of the FAT file system such as the difficulty to use and inefficient access , a new format named Simplified-FAT format for data storing in CF card is presented. It is proved that Simplified-FAT format is simple, efficient, stable and compatible with Windows OS and it is suitable to be used in bulky data storing system.
