ABSTRACT:
An address lock register managing address exclusive control is made to retain not only an address but also a request type, an access destination, and a cache block. Upon receiving a new request, firstly, the address lock register is referred to judge whether an exclusive condition is satisfied, that is, whether an address match, CPU match, LINE match or SX-WAY match is present, and whether the address lock is busy in accordance with the output of an AND circuit. Further, the configuration is such that the address lock register is referred to confirm that the addresses are identical to each other, and, additionally, the response source is validated to be identical to a lock flag and the new request causing the lock is validated to be consistent with the response request upon receiving a response request so that the lock is not released unless a correct response is made.
