  • Method and apparatus for determining metric for selective caching
    Patent number: 10007614
    Abstract: System and method determining metric for selective caching, comprising determining a result of an access to a cache for at least one tracked attribute; determining a count value for the at least one tracked attribute in a translation look-aside buffer entry corresponding to the access to the cache in accordance with the determined result; comparing the count value for the at least one tracked attribute with a threshold associated with the at least one tracked attribute; assigning the metric of sticky property to a cache line corresponding to the translation look-aside buffer entry when the count value for at least one of the at least one tracked attribute exceeds the threshold. Selective caching then assigns different protection status to the cache lines with and without sticky property; and evicting a cache line in accordance with a cache eviction policy starting with the cache lines with the lowest protection status.
