First-level fetch
First-level descriptor
Translation base
Translation base
Bits [31:14] of the TTBR are concatenated with bits [31:20] of the MVA to produce a
30-bit address as shown in Figure 3-3.
This address selects a 4-byte translation table entry. This is a first-level descriptor for
either a section or a page table.
The first-level descriptor returned is a section descriptor, a coarse page table descriptor,
or a fine page table descriptor, or is invalid. Figure 3-4 on page 3-9 shows the format of
a first-level descriptor.
