How to Improve Hard Disk Operation Speed of Mobile Switching System

摘要

The present invention relates to a bitmap in which a file system included in a part of an operating system for driving a main processor of a mobile communication switch reflects the use of a block, which is a logical partition unit of a disk, for creating and destroying a file or for formatting a disk. In order to update the bitmap, the bitmap is updated by performing an operation directly on the cache memory to improve the operating speed of the disk by speeding up the update speed. When the update of the bitmap is required, the requested bit is updated. The map area is saved from the disk to the cache memory, and the data of the bitmap area stored in the cache memory is directly updated. In this way, the contents of the cache memory are directly updated, and the contents of the updated cache memory are written to the disk, thereby rapidly improving the bitmap of the disk.
