Abstract
A tag match determination unit determines, in response to an acquisition request for predetermined data, whether predetermined data is present in a primary cache. When the predetermined data is not present in the primary cache, the move-in buffer outputs the acquisition request for the predetermined data to a secondary cache management unit or the storage device and holds determination purpose information based on state information on a predetermined area that stores therein the predetermined data. A storage processing unit determines, when an acquired response from the secondary cache management unit or the storage device is a predetermined type, based on the determination purpose information, whether or not to acquire the state information stored in the primary cache; invalidates the predetermined area when it is determined not to acquire the state information; and stores, in the predetermined area, the predetermined data included in the response.
