Abstract: A versioning group cache system uses cache keys which each include, amongst other things, version information and a group key. When a cache key is first updated to include these, the cache system determines the group key and adds version information thereto to produce the cache key, which is mapped to cached data. When the cache key is later updated, the version information is updated to produce an updated cache key which is mapped to the cached data. The cache key updating is in response to a change request received at the cache system. The change request includes a command processable at the cache system in connection with cached data and/or cache keys. For example, the change request may be a request for a batch deletion of cache keys. The versioning group cache system fulfills the change requests with efficient use of system resources.

Abstract: A method for controlling dynamic change of a screen refresh rate and an electronic device are provided. In a scenario of dynamic change of the refresh rate, a refresh rate switching instruction may be sent immediately through an added refresh rate setting interface (displaySetFps) within a current ith frame period before a current Vsync periodicity ends. After receiving the refresh rate switching instruction, a DDIC drives a display screen to switch a screen refresh rate, and then the DDIC returns a new TE signal. After receiving the new TE signal, SurfaceFlinger starts a new Vsync periodicity corresponding to a switched screen refresh rate. In an embodiment of this application, a switching speed at which the screen refresh rate is switched may be increased by adding a new path. For example, it may be ensured that each switching of the screen refresh rate is completed within one frame.
