Based Embedded Operating System, File System And Its Applications In The Vehicle Traveling Data Recorder

At first this article introduces the research backgroud of the paper, i.e. the development of Automobile Data Recorder based on Embedded Operating System and File System, the emphasis and direction of the research are pointed out. The concepts of Embedded system are also introduced. What is E.S. and how to develop it are given in details.And then the realizing of the Automobile Data Recorder is introduced.The hardware is given in detail. The real-time kernel of μC/OS, which is a kernel of real time operation system, is introduced.First the concepts are introduced, then through analysis and research of source codes of μC/OS, the kernel are known well. And the research plan is given based on ARM processor. The resear of I/O part is introduced.And the I/O devices in Recorder are disscussed in details,we also realization based on μC/OS. The File System - uMFS is discussed in details.First the principles of file system is discussed.Then the details of how to design and realizing μMFS are introduced, mainly based on NandFlash. Finally the whole work is summarized,the disadvantages and the further work are pointed out.
