ABSTRACT:
In an information processing apparatus composed of two or more processor units each including a cache memory and a processor which accesses stored data via the cache memory, and a main storage, a cache memory control method in which, using information concerning control object data, such as identification of a storage area and whether or not the data are program data, a judgment is made as to whether or not the data has a high possibility of being used by another processor. If the data has a high possibility of being used by another processor, the cache memory is controlled by the store-through system. If the data has a low possibility of being used by another processor, the cache memory is controlled by the store-in system.
