9.11 Translating Large Page References
·
Figure 9-8: Large page translationillustrates the complete translation sequence for
a 64Kb Large Page. Note that since the upper four bits of the Page Index and low-order
four bits of the Page Table index overlap, each Page Table Entry for a Large Page must
be duplicated 16 times (in consecutive memory locations) in the Page Table.
