    Abstract: A processor is described having cache circuitry and logic circuitry. The logic circuitry is to manage the entry and removal of cache lines from the cache circuitry. The logic circuitry includes storage circuitry and control circuitry. The storage circuitry is to store information identifying a set of cache lines within the cache that are in a modified state. The control circuitry is coupled to the storage circuitry to receive the information from the storage circuitry, responsive to a signal to flush the cache, and determine addresses of the cache therefrom so that the set of cache lines are read from the cache so as to avoid reading cache lines from the cache that are in an invalid or a clean state.
