<p>A processor (12 to 12g) includes a cache memory (12a) that temporarily retains data stored in a main storage (17 to 24). The processor includes a processing unit (40 to 40b) that executes an application by using the data retained in the cache memory (12a), The processor includes a storing unit (12c, 12e, 42, 46) that stores therein update information indicating data that has been updated by the processing unit (40 to 40b) within the time period specified by the application executed by the processing unit (40 to 40b). The processor includes a write back unit (52) that, when the time period specified by the application ends, writes back, to the main storage (17 to 24) from the cache memory (12a), data that is from among the data retained in the cache memory (12a) and that is indicated by the update information stored in the storing unit (12c, 12e, 42, 46).</p> |
