Abstract
This disclosure provides a cache replacing method applied to a heterogeneous multi-core system, the method including: determining whether a first application currently running is an application running on the GPU; when it is determined that the first application currently running is an application running on the GPU, determining a cache priority of first data accessed by the first application according to a performance parameter of the first application, the cache priority of the first data including a priority other than a predefined highest cache priority; and caching the first data into a cache queue of the shared cache according to a predetermined cache replacement algorithm and the cache priority of the first data, and replacing data in the cache queue.
