METHOD AND APPARATUS FOR MANAGING TEMPORAL AND NON-TEMPORAL DATA IN A SINGLE CACHE STRUCTURE

摘要

A method is provided for managing temporal and non-temporal data in the same cache structure. The temporal or non-temporal character of data targeted by a cache access is determined (220), and a cache entry for the data is identified. When the targeted data is temporal, a replacement priority indicator associated with the identified cache entry is updated to reflect the access (210). When the targeted data is non-temporal, the replacement priority indicator associated with the identified cache entry is preserved (230). The method may also be implemented by employing a first algorithm to update the replacement priority indicator for temporal data and a second, different algorithm to update the replacement priority indicator for non-temporal data.
