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.
