AT91SAM9XE128/256/512 Preliminary
A first level of address decoding is performed by the Bus Matrix, i.e., the implementation of the
Advanced High performance Bus (AHB) for its Master and Slave interfaces with additional
features.
Decoding breaks up the 4 Gbytes of address space into 16 banks of 256 Mbytes. The banks 1 to
7 are directed to the EBI that associates these banks to the external chip selects EBI_NCS0 to
EBI_NCS7. Bank 0 is reserved for the addressing of the internal memories, and a second level
of decoding provides 1 Mbyte of internal memory area. Bank 15 is reserved for the peripherals
and provides access to the Advanced Peripheral Bus (APB).
Other areas are unused and performing an access within them provides an abort to the master
requesting such an access.
Each Master has its own bus and its own decoder, thus allowing a different memory mapping
per Master. However, in order to simplify the mappings, all the masters have a similar address
decoding.
Regarding Master 0 and Master 1 (ARM926 Instruction and Data), three different Slaves are
assigned to the memory space decoded at address 0x0: one for internal boot, one for external
boot, one after remap, refer to Table 8-3, “Internal Memory Mapping,” on page 25 for details.
A complete memory map is presented in Figure 8-1 on page 20.
