Abstract
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, 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. When the targeted data is non temporal, the replacement priority indicator associated with the identified cache entry is preserved. 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.
