The AMD-K6-IIIE+ processor can physically address up to four
Gbytes of memory. This memory can be segmented into pages.
The size of these pages is determined by the operating system
design and the values set up in the page directory entries (PDE)
and page table entries (PTE).
The processor can access both 4-Kbyte pages and 4-Mbyte
pages, and the page sizes can be intermixed within a page
directory. When the page size extension (PSE) bit in CR4 is set,
the processor translates linear addresses using either the
4-Kbyte translation lookaside buffer (TLB) or the 4-Mbyte TLB,
depending on the state of the page size (PS) bit in the page
directory entry. Figures 46 and Figure 47 on page 57 show how
4-Kbyte and 4-Mbyte page translations work.
