用于数控车床的嵌入式Linux文件系统的设计与实现

Design and realization of embedded file system for numerically controlled lathe

针对数控车床对系统功能、空间利用率、时间效率的需求,提出并实现了一种用于数控车床的嵌入式Linux文件系统。该系统以Cramfs为根文件系统,Yaffs作为用户的数据存储分区,用Tmpfs存储临时数据,采用Initramfs引导根文件系统。实验结果表明,系统的空间利用率高,启动时间快。

Aiming at meeting requirements of numerically controlled lathe such as system function, space utilization and time efficiency, a file system of embedded Linux used for numerically controlled lathe is presented, using Cramfs as root file system, Yaffs as user＇ s data partition, Tmpfs as system＇ s temporary＇ data, and Initramfs as leading root file system. The experiment shows that the size is smaller and boot is faster.
