The Cortex-A72 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 as either:
- Big-endian format.
- Little-endian format.
See the ARM® Architecture Reference Manual ARMv8 for more information about big-endian and little-endian memory systems.
