defined segment table to provide an 80-bit virtual address space (to replace the segment registers used in 32-bit addressing that provided a 52-bit virtual address space)
The address translation mechanism for 64-bit processors is similar to the translation mechanism used on 32-bit implementations, except that the segment registers are replaced with a segment table to handle the larger logical and virtual address spaces, and the page table format was extended to accommodate the larger virtual and physical address spaces.
