Problems solved by technology

[0003] In related technologies, the scheme of UFS combined with the host performance booster HPB (Host Performance Booster) is used to perform data reading. Although this scheme has a relatively fast data reading speed, the following problems still exist: the reading ratio of HPB is low and The waste of cache resources, so that the read performance cannot be fully reflected

Abstract

The invention discloses a data caching method and a data caching device.The method comprises the steps that in response to a read request sent by a host, a process corresponding to the read request is determined; according to historical process information in the cache, historical access information of a process corresponding to the read request is obtained, the historical process information comprises historical access information of at least one process, and the historical access information of each process comprises popularity information of one or more data blocks historically accessed by each process; according to historical access information of a process corresponding to the read request, determining a first data block of which the heat information of historical access of the process corresponding to the read request meets a first preset condition; and the physical address of the first data block into the cache from storage equipment is loaded. According to the scheme, the HPB read proportion in all read operations can be high, it is guaranteed that the cached data blocks can be frequently accessed subsequently, and therefore the read performance of equipment is improved.

Description

technical field [0001] The present disclosure relates to the storage field, and more specifically, to a data caching method and a data caching device. Background technique [0002] At present, hosts based on UFS (Universal Flash Storage, universal flash storage) storage (such as Android mobile phones) need to read data from UFS during operation. The speed of reading data directly affects the running speed of the device, such as large-scale games. This is even more evident at startup. [0003] In related technologies, the scheme of UFS combined with the host performance booster HPB (Host Performance Booster) is used to perform data reading. Although this scheme has a relatively fast data reading speed, the following problems still exist: the reading ratio of HPB is low and The waste of cache resources makes the read performance not fully reflected. Contents of the invention [0004] The present disclosure provides a data caching method and a corresponding data caching dev...
