US 2026/0086943 A1 · CACHE MANAGEMENT METHOD, CACHE MANAGEMENT DEVICE, AND ELECTRONIC APPARATUS

Abstract

A cache management method may include receiving a data access request associated with first data, incrementing activity information of first data, and adjusting a priority of the first data based on the incremented activity information of the first data, in response to the first data already being stored in a cache, and deleting second data, the second data being data having a lowest priority level in the cache, loading the first data into the cache, and setting the priority and the activity information of the first data, in response to the first data not already being stored in the cache and the cache being full.

Claims20

Dependent claims

A cache management method, comprising:

receiving a data access request associated with first data;
incrementing activity information of the first data, and adjusting a priority of the first data based on the incremented activity information of the first data, in response to the first data already being stored in a cache;
and
deleting second data, the second data being data having a lowest priority level in the cache, loading the first data into the cache, and setting the priority and the activity information of the first data, in response to the first data not already being stored in the cache and the cache being full.

A cache management device, comprising:

memory configured to store a cache;
and
processing circuitry configured to execute computer readable instructions to,
receive a data access request associated with first data;
increment activity information of the first data, and adjust a priority of the first data based on the incremented activity information of the first data, in response to the first data being stored in the cache;
and
delete second data, the second data being data having a lowest priority level in the cache, load the first data into the cache, and set the priority and the activity information of the first data, in response to the first data not already being stored in the cache and the cache being full.
