    摘要: Disclosed is a file accessing method of a file system which manages data by a block unit of a fixed size having an index and provides information associated with a file via a plurality of entries having an index and linked information of each of blocks forming the file. The file accessing method includes providing a hint information area to each of the plurality of entries so as to record an access mode or continuous allocation information for the file, allocating the plurality of blocks to record contents of the file, and recording the access mode in each of the hint information areas of entries corresponding to a first chain group of the allocated blocks and the continuous allocation information in the hint information area of at least one entry corresponding to a second chain group of the allocated blocks.

    摘要: A method and apparatus for reducing a page replacement time in a system using a demand paging technique are provided. The apparatus includes a memory management unit which transmits a signal indicating that a page fault occurs, a device driver which reads a page having the page fault from a nonvolatile memory, and a page fault handler that searches and secures a space for storing the page having the page fault in a memory. The searching and securing of the space in the memory is performed within a limited time calculated beforehand and a part of data to be loaded to the memory of the system is stored in the nonvolatile memory.

    摘要: An apparatus for reducing a page fault rate in a virtual memory system includes a page table stored in a main storage unit which stores a reference address so as to read page information from the main storage unit; a buffer unit which stores a portion of the page table; and a processor which reads data from the main storage unit or which stores data in the main storage unit. When changing information for referring to a first page that exists in the page table, the processor performs a task invalidating information related to the first page in the buffer unit. A method of reducing the page fault rate includes resetting reference information stored in the page table; detecting whether the reference information exists in a buffer unit; and invalidating the reference information when the reference information exists in the buffer unit.
