Cache replacing method and apparatus, heterogeneous multi-core system and cache managing method

A cache replacing apparatus applied to a heterogeneous multi-core system, the heterogeneous multi-core system including at least one central processing unit CPU, at least one graphic processing unit GPU and a shared cache, the apparatus including:

• an application determining unit configured to determine whether a first application currently running is an application running on the GPU;
• a cache determining unit configured to, when it is determined that the first application currently running is an application running on the GPU, determine 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
• a data caching unit configured to cache 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 replace data in the cache queue.
