Translation table base
31
The hardware translation process is initiated when the TLB does not contain a
translation for the requested MVA. The Translation Table Base Register (TTBR), CP15
register c2, points to the base address of a table in physical memory that contains section
or page descriptors, or both. The 14 low-order bits [13:0] of the TTBR are
Unpredictable on a read, and the table must reside on a 16KB boundary. Figure 3-1
shows the format of the TTBR.
The translation table has up to 4096 x 32-bit entries, each describing 1MB of virtual
memory. This enables up to 4GB of virtual memory to be addressed.
Figure 3-2 on page 3-7 shows the table walk process.
