Abstract

The invention discloses a page caching method based on a nonvolatile medium. The page caching method comprises: dividing the nonvolatile medium to serve as a cache of back-end equipment; when a data modification command is received, executing the data modification command on the nonvolatile medium to set the page data to be modified dirty, and recording the flashing state of the dirty page data; and correspondingly processing the dirty page data according to the flash state when the system is shut down or the related program exits. The invention provides a technical scheme. By utilizing the characteristic that the non-volatile medium does not lose data after power failure, the non-volatile medium is divided into the caches of the rear-end equipment, so that relevant measures of memory power failure protection do not need to be set, cache data loss during memory power failure can be avoided, and the security of computer system data is improved. The invention further provides a caching system and equipment based on the nonvolatile medium and a computer readable storage medium which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of caching, and in particular to a non-volatile medium-based page caching method, system, device, and computer-readable storage medium. Background technique [0002] As we all know, in order to improve computer performance in existing systems, a large number of caches are used, including page caches associated with ordinary files and swap partitions associated with swap partitions. The page cache of the associated ordinary file contains a lot of user data, which may not have been synchronized with the underlying device. [0003] Regarding cache data processing, there is also a related solution now, that is, when the system is powered off, the capacitor embedded in the system will be used for power supply in order to save the cache data. However, if the power-failure protection related measures of the memory fail, data may be lost when the power of the memory is lost. [0004] Therefore, how to avoid cache ...
