ABSTRACT:
A virtual memory control multiprocessor system has a plurality of processors each having a translation lookaside buffer (TLB). A purge request source processor commonly supplies a purge request signal to other processors so as to cause them to perform TLB purge operations. A purge end signal sent back from other processors is stored in flip-flops in the source processor in units of processors. The source processor detects the end of TLB purge operations of all processors, in accordance with the statuses of the flip-flops.
