Abstract

A method for determining a single reference residency time of a cache comprises the steps of causing test data to be staged to the cache and measuring a response time after a wait time has elapsed. The measuring step is repeated for a plurality of values of wait time. The method also includes the step of determining a boundary value of the wait time. A wait time of less than or equal to the boundary value yields a corresponding response time representing a cache hit and a wait time of greater than the boundary value yields a corresponding response time representing a cache miss. The boundary value is an estimate of the single reference residency time of the cache.
