<p>A cache controller receives a reference request from a CPU executing a program in which information indicative of a reference request specifying in shared memory, an area not having an update request and information indicative of a snoop reference request are distinguished from one another. When the reference request specifying an area not having the update request is received, the cache controller acquires from the shared memory and without performing a snoop process, information stored in the specified area. The cache controller stores the information acquired from the shared memory to the cache memory of the CPU executing the program.</p> |
