Cache set replacement order based on temporal set recording

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.

1. A computer system for cache management, the system comprising:
a processing circuit, and a cache, the system configured to perform a method comprising: tracking, by the processing circuit, a miss count and a hit position field for an instruction requesting access to a data element in the cache, the miss count and the hit position field generated by a previous execution of the instruction and saved in a tracking table; wherein the tracking table comprises the miss count and the hit position field associated with an instruction address for the instruction requesting access to the data element; and placing the data element in a hierarchical replacement order based on at least one of the miss count and the hit position field, the hit position field comprises a hierarchical position associated with the instruction related to the data element.
