Hi All,

Arm Processor supports both Big Endian and Little Endian So that operating system can use both.
But what is the deciding factor whether to choose Little Endian or Big Endian?

If you are starting from scratch with new software then it really doesn't matter.

The main driver is probably really either a personal preference or desire for compatibility with software running on other platforms (x86 is little-endian, PPC is big-endian), and the types of data sets you are working with.
When optimizing software, consider that the quickest code to run is the bit you removed from the call path.

The endianness of the system as a whole is implementation dependent and is determined by the circuitry that
connects the processor to its peripheral components
