<p>On a multiprocessor device, a cache line of a cache memory on each processor is divided into a plurality of partial writable regions. Each processor is given a partial exclusive right which is the exclusive right for each partial writable region. On a cache tag (30) of the cache memory, partial writing status PM is registered onto a cache status (32) of an entry (31) for registration of information on the partial writable regions. Setting of the partial exclusive right eliminates false sharing.</p> |
