Translating small page references
Figure 6-6 illustrates the complete translation sequence for a 4KB small page. Page
translation involves one additional step beyond that of a section translation. The level 1
descriptor is the page table descriptor, and this points to the level 2 descriptor, or page
table entry. As the access permissions are now contained in the level 2 descriptor they
must be checked before the physical address is generated. The sequence for checking
access permissions is described in Fault checking sequence on page 6-22.
