摘要：
A technique is provided for cache management of a cache. The processing circuit determines a miss count and a hit position field during a previous execution of an instruction requesting that a data element be stored in a cache. The miss count and the hit position field are stored for a data element corresponding to an instruction that requests storage of the data element. The processing circuit places the data element in a hierarchical order based on the miss count and/or the hit position field. The hit position field includes a hierarchical position related to the data element in the cache.
