FILE PAGE MANAGEMENT UNIT, PROCESSING DEVICE AND FILE PAGE MANAGEMENT METHOD

摘要

Provided are a file page management unit, a processing device and a file page management method. The file page management unit (10) comprises: a register (11), which is used for storing a file page table of a progress, wherein the file page table is used for recording information about a virtual address field allocated for a target file and a physical page base address of the target file, wherein the target file is stored in a non-volatile memory by taking a physical page as a unit; and a processing circuit (12), which is used for querying the file page table stored in the register according to a target virtual address when the progress accesses the target file so as to determine the physical page base address corresponding to the target virtual address. The processing circuit is further used for determining a physical page address of the target file according to the physical page base address and the target virtual address, and sending the physical page address to a memory controller. The file page management unit can improve a file management performance.
