CF卡在大容量數(shù)據(jù)存儲(chǔ)系統(tǒng)的典型應(yīng)用

介紹了一種采用數(shù)字信號(hào)處理器、CF 卡以及數(shù)據(jù)采集電路構(gòu)建的大容量數(shù)據(jù)存儲(chǔ)系統(tǒng)，并針對(duì)FAT 文件系統(tǒng)實(shí)際操作困難、訪問(wèn)效率不高等弱點(diǎn)，提出了CF卡中數(shù)據(jù)存儲(chǔ)的一種新格式——簡(jiǎn)化FAT 格式。實(shí)踐證明了，該格式操作簡(jiǎn)單、執(zhí)行效率高、穩(wěn)定可靠且可為Windows 操作系統(tǒng)所識(shí)別，適合大容量存儲(chǔ)系統(tǒng)應(yīng)用。

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.
