ABSTRACT:
In a multiprocessor system having a hierachal memory device employing a virtual memory system, serial communication means which makes it possible for memory management units, which are disposed for CPUs, respectively, to communicate with one another, so that any change of common memory management information can be exchanged directly between the memory management units. As a result, it is not necessary for each CPU to inform the memory management unit of any change of the memory management information by an operating system, so that the overhead of communication between CPUs can be reduced and memory management can be made correctly without applying any load to the operating system even when any change occurs in the memory management information.
