WIPO Patent Application WO/2018/157278

A1

Disclosed are a cache management method, a cache manager, a shared cache, and a terminal, relating to the technical field of storage. The method is applied to a cache manager (121). The method comprises: during the process of a first thread accessing a first volatile cache partition (1221) in a volatile memory (122), if the first thread needs to carry out a time-consuming operation, backing up first data in the first volatile cache partition (1221) to a non-volatile memory (123), wherein threads locked by any two volatile cache partitions (1221) are different and each volatile cache partition (1221) is prohibited from being accessed by a thread different from the thread locked by the volatile cache partition (1221); and during the process of the first thread carrying out the time-consuming operation, setting the first volatile cache partition (1221) to be in a state of being accessible to a thread different from the first thread. By means of this method, the problem of the cache utilization rate of a terminal being relatively low is solved, and the cache utilization rate of the terminal is improved. This method can be used for a terminal.
