The system comprises the steps of determining by a processing circuit a miss count and a hit position field of a data element corresponding to an instruction requesting storage said element in the cache, the miss count and hit position field being generated by a previous execution of the instruction; and placing the data element in a hierarchical replacement order based on the miss count and/or the hit position field, where the hit position field comprises a hierarchical position related to the data element. If the miss count is not set, the element may be placed according to an inverted relationship of the hierarchical position in the hit position field, wherein following a cache hit the element is prevented from moving higher in the replacement order than the inverted relationship to the hierarchical position. If miss count and hit position field conflict, then the miss count may be used to determine the hierarchical replacement order. |
