US 2017/0371807 A1 · CACHE DATA DETERMINING METHOD AND APPARATUS

Abstract

The present embodiments provide a cache data determining method and apparatus, and pertain to the field of computer technologies. The method includes: acquiring a data identifier of read cache miss data; selecting, based on the acquired data identifier, a data identifier of to-be-determined data; recording data identifiers by groups; collecting statistics on quantities of occurrence times, in each group, of the data identifiers; and selecting target to-be-determined data according to the quantities of occurrence times, and determining the target to-be-determined data as cache miss data to be written into a cache memory. Data identifiers are recorded by groups, and after statistics on quantities of occurrence times, in each group, of the data identifiers is collected, target to-be-determined data is selected according to the quantities of occurrence times, and the target to-be-determined data is determined as cache miss data to be written into a cache memory.
