| 摘 要： | 基于嵌入式文件系统CFFS提出一种快速挂载机制。该机制引入“静态超级块”、“引用节点”以及“页位图”等数据结构并采取相应算法，避免了在文件系统挂载过程中进行的全芯片扫描。测试表明，这种快速挂载机制减少了闪存文件系统在大容量NAND芯片上的挂载时间。

| Abstract: | Based on embedded file system Compact Flash File System(CFFS) which is oriented for large-scale NAND flash chips, this paperproposes a fast mounting mechanism.The mechanism uses the data structures such asstatic super block,reference node,page bit mapandadopts some corresponding algorithms, soit avoids the full scanning of the flash chip when the file system is being mounted.Test shows that themechanism can reduce the mounting time significantly when the file system is mounted on large-scale NAND flash chip... |
