VxWorks文件系统中的CBIO机制研究

Research on CBIO Mechanism of VxWorks File system

为了提高文件系统的块输入输出效率,新版本的VxWorks文件系统中引入了CBIO机制。本文分析了支持该机制的各个CBIO模块的功能、内在联系,对CBIO机制所采用的关键技术进行了深入的研究,给出了利用CBIOAPI创建CBIO设备分区并在各分区上建立两种不同文件系统的实现过程。

In order to enhance the IO efficiency, the file system of new version VxWorks introduces CBIO mechanism. This paper analyzed the function and inter-relationship of each CBIO module that support this mechanism, then we looked into the key technology that adopted by CBIO mechanism. An implementation procedure is given, in which we use tile CBIO API to create the CBIO device partition, and setup two different file systems on the partition.
