Abstract
A cache cleaner controller is described. In one or more examples, an apparatus includes a cache directory including status bits associated with cache locations within cache storage and a cache cleaner controller. The cache cleaner controller is configured to detect that a cache cleaner threshold has been reached. The cache cleaner threshold defines that a threshold number of the status bits indicate data maintained at the cache locations, respectively, has been changed. The cache cleaner controller is also configured to cause the data indicated as changed by the status bits to be copied from the cache locations within cache storage to the physical volatile memory.
