3.8. Memory model

The Cortex-A9 processor views memory as a linear collection of bytes numbered in ascending order from zero. For example, bytes 0-3 hold the first stored word, and bytes 4-7 hold the second stored word. The processor can store words in memory in either big-endian format or little-endian format.

Instructions are always treated as little-endian.


ARMv7 does not support the BE-32 memory model.
