Prior art methods of maintaining coherency among multiple TLBs in a multiprocessor system were time-consuming. One microprocessor halted all other microprocessors in the system, and sent an interrupt to each of the halted microprocessors. Rather than invoking an interrupt handler, the TLB shootdown operation of the present invention provides for a TLB flush transaction communicated between multiple processors on a host bus. One microprocessor issues a TLB flush request on the host bus. The TLB flush request includes a page number. The microprocessors receiving the request invalidate the TLB entry corresponding to the page number. |
