    • A file system having a cache memory management function is provided to minimize disk access by installing a cache memory controlling module to the inside of the file system and utilizing the cache memory controlling module. If a read command for a file is received from an API(Application Program Interface)(21), a cache memory manager(23) reads file contents from a cache memory(40) and provides the read file contents to the API. If the corresponding file contents are not found in the cache memory, the cache memory controller stores the corresponding file contents accessed by a device driver(22) to the cache memory. A file reference frequency manager(24) increases a reference frequency of the file if the file is searched from a reference frequency table. The cache memory manager stores the file contents over the predetermined reference frequency to the cache memory by comparing the reference frequency stored in the table with the predetermined reference frequency.
    • 提供具有高速缓冲存储器管理功能的文件系统,以通过将高速缓冲存储器控制模块安装到文件系统的内部并利用高速缓冲存储器控制模块来最小化磁盘访问。 如果从API(应用程序接口)(21)接收到用于文件的读取命令,则高速缓冲存储器管理器(23)从高速缓冲存储器(40)读取文件内容,并将读取的文件内容提供给API。 如果高速缓冲存储器中没有找到相应的文件内容,则高速缓冲存储器控制器将由设备驱动器(22)访问的相应的文件内容存储到高速缓冲存储器。 如果从参考频率表搜索文件,则文件参考频率管理器(24)增加文件的参考频率。 高速缓冲存储器管理器通过将存储在表中的参考频率与预定参考频率进行比较,将预定参考频率上的文件内容存储到高速缓存存储器。
