Abstract

A cache management method, a cache manager, a shared cache and a terminal, relating to the field of storage technology, the method is used for a cache manager (121), and the method includes: accessing the first thread in the volatile memory (122) In the process of a volatile cache partition (1211), if the first thread needs to perform a long time-consuming operation, the first data in the first volatile cache partition (1211) is backed up to the non-volatile memory (123 ), the threads locked by any two volatile cache partitions (1221) are different, and each volatile cache partition (1221) is prohibited from being accessed by threads different from the threads locked by the volatile cache partition (1221); in the first During the process of the thread performing a long time-consuming operation, the first volatile cache partition (1211) is set to a state that can be accessed by a thread different from the first thread. The method solves the problem of low cache utilization rate of the terminal, improves the cache utilization rate of the terminal, and can be used in the terminal.

Description

Technical field [0001] The present application relates to the field of storage, and in particular, to a cache management method, a cache manager, a shared cache, and a terminal. Background technique [0002] A processor and volatile memory are provided in the terminal. The processor includes a plurality of processor cores, each processor core includes a plurality of threads, each thread being used to access data in the volatile memory, such as writing data in the volatile memory. Multiple threads in the same processor core can share vulnerability memory such that the plurality of threads can simultaneously access data in volatile memory. [0003] Currently, in a shared volatile memory, the data will be replaced by other data when a certain amount of data is not accessed. When a thread is executing a longer operation (such as data loss operation), the thread is originally accessed in the volatile memory will be replaced by the data of other threads due to the long time, and the da...
