ABSTRACT:
A method of identifying a shared main memory page containing a physical address corresponding to a virtual address included in an issued write instruction. The method includes determining the selected virtual address is not within a reach of a TLB entry that is currently loaded in the TLB. If one of the BBR entries includes the selected virtual address, then identifying one of the BBR entries that includes the selected virtual address, calculating a new TLB entry that includes the selected virtual address and loading the new TLB entry in the TLB.
