Abstract:
A system and method for identifying a TLB entry having a physical address that is within a specified range are disclosed. The method includes obtaining a tentative TLB entry from a page table entry and accessing a physical address associated with the tentative TLB entry. The method further includes comparing the physical address of the tentative TLB entry with a predetermined range of addresses. If the physical address is within the finite range of addresses, an exception is invoked. In response to the exception, the physical address and/or an attribute of the tentative TLB entry can be modified. The tentative TLB entry can then be stored in a TLB.
