PURPOSE:To suitably treat the difficulties by housing the locked address of microprogram words or address of instruction words, by setting a lock address housing section in addition to the housing section of processor number on the lock information housing section. CONSTITUTION:When an object to be locked is generated, a housing section 1 of processor number corresponding to the object to be locked is read out and it is checked whether other processor than that locks the object. In case when other processor had already locked it, it should be judged whether the release of the object to be locked should be waited or not. When the object is not set in locking condition, microprogram words are written in a lock address housing section 2. Next, information turned-on bit corresponding to the number of the processor is written in the housing section 1. |
