Abstract

PURPOSE: To ensure compatibility when each processor updates each TLB by invalidating the block of a parallel cache memory corresponding to an altered block and the block of a virtual memory-real memory converting means (TLB).
CONSTITUTION: When an element processor 2 writes data into a logical space A, namely a physical space B, and sets the altering flag of a TLB 5 and a parallel cache memory 9 at '1', an alteration notifying part 10 notifies the value to the other parallel cache memory part. The notification is received by an alteration receiving part 14 of a parallel cache memory part 8, and the corresponding cache block and TLB entry on the element processor 2 side are invalidated. Consequently when the element processor 2 is about to access a logical space C, a TLB mishit is decided, whereas, page table entry (PTE) data are supplied from the parallel cache memory 9. Thus the incompatibility of the contents of the TLB is eliminated.
