摘　　要：目前,NAND FLASH技术有了飞速发展,它以能抗震动,功耗小,容量大,掉电数据不丢失等特点而成为嵌入式系统的重要组成部分。如何合理、高效、可靠地使用NAND FLASH就显得尤为重要。讨论了在基于VxWorks的软件平台和基于AMCC公司的PPC440epx、三星公司的K9F2G08Q0M为核心的硬件平台上,实现TrueFFS文件系统的具体办法。以此为基础的系统在某机载设备上得到成功运用。At present, NAND FLASH technology is rapidly developing. Its antivibration,small power consumption,large capacity,power-down data is not lost,which make it is one important part of an embedded system. Thus,how reasonable, efficient and reliable use of NAND FLASH is particularly important. This paper describes how to achieve TrueFFS file system based on the VxWorks software platform and hardware platforms consisting of AMCC＇s PPC440epx and Samsung＇s KgF2G08QOM. These technologies are applied on the on - board equipment.
