Problems solved by technology

However, when the related technology eliminates the cache content, the determination of the cache content to be eliminated is not accurate enough, which leads to serious cache pollution, reduces the hit rate of the cache, and seriously affects the access speed to data.

Abstract

The invention discloses a cache management method and device, computer equipment and a storage medium, and the method comprises the following steps: determining the access time and access frequency corresponding to cache contents when an access request for the cache contents in a cache is received; determining the ratio of the access times to the maximum access times corresponding to the cache content in the cache to obtain the access frequency corresponding to the cache content; when a cache elimination condition is met, determining a popularity value of each cache content according to the access time and the access frequency corresponding to each cache content in the cache; determining cache content to be eliminated according to the popularity value of each cache content in the cache; and deleting the cache content to be eliminated from the cache. According to the method, the time dimension and the access frequency dimension are combined to comprehensively consider the cache contentto be eliminated, so that the cache content to be eliminated is determined more accurately, cache pollution is avoided, and the cache hit rate is increased.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a cache management method, device, computer equipment and storage medium. Background technique [0002] Cache (Cache) is a small-capacity memory between the central processing unit (Central Processing Unit, CPU) and the main memory. The access speed is faster than the main memory and close to the CPU. It can provide instructions and data to the CPU at high speed and improve the execution speed of the program. Cache technology is an important technology adopted to solve the speed mismatch between CPU and main memory. [0003] In related technologies, when the cache space is completely occupied, that is, when the cache is full, it is necessary to eliminate some cache contents in the cache, so as to release part of the cache space. However, when the relevant technology eliminates the cache content, the determination of the cache content to be eliminated is not accurate e...
