摘　　要：智能芯片离不开软件的支持,这些软件和配置文件一般存储在闪存中,处理器启动时从闪存中读取启动代码,然后由启动代码将各个软件模块和配置文件加载到相应的芯片,最后引导操作系统。本文介绍了一种可靠高效的适合于启动闪存使用的文件系统,包括文件系统的特点、结构、实现原理,并和其他同类型文件系统进行了比较。Smart cards need the support of software which exists in Flash with configuration files. The processor reads start code from Flash, then loads software modules and configuration files to the corresponding chip, and boots the operating system. The paper introduces a reliable efficient Flash file system, which is suitable for system boot Flash. The introduction focuses on the architecture, princi- ple, and advantages of the file system, and compares it with other similar file systems.
