Abstract
A VIVT (virtual index, virtual tag) cache ( ) uses an interruptible hardware clean function to clean dirty entries in the cache during a context switch. A MAX counter ( ) and a MIN register ( ) define a range of cache locations which are dirty. During the hardware clean function, the MAX counter ( ) counts downward while cache entries at the address given by the MAX counter ( ) are written to main memory ( ) if the entry is marked as dirty. If an interrupt occurs, the MAX counter is disabled until a subsequent clean request is issued after the interrupt is serviced.
