| 摘 要： | 详细介绍了一个嵌入式文件系统CEFS的设计与实现。该文件系统是基于实时嵌入式操作系统CR-TOSII内核,采用IMFS和FAT位图文件系统格式实现的。CEFS文件系统分为3个实现层次,自底向上分别是：设备驱动程序、高速缓存管理和文件系统核,并向用户提供了基于POSIX的文件系统API接口。它的最大优点就是文件系统的开放式体系结构。

| Abstract: | The design and implementation of the embedded file system CEFS is introduced.It is based on the real-time operation system CRTOSII.The CEFS is implemented using the technology of the IMFS and the FAT bitmap which is a widely used file system format.The CEFS is divided into three levels: the drivers of the devices,the management of the Cache and the kernel of the file system.The CEFS also has provided the POSIX interface. |
