C programs can perform the same operations by using endian swap routines.
The PowerPC processor supports a little-endian addressing mode that changes the way in which real addresses are used to access physical storage. It applies a logical exclusive-OR operation with a constant to the lowest 3 bits of the address, using a different constant for each size of data. This modifies each address to the value it would have if the PowerPC processor used little-endian addressing. This appendix presents solutions to some of the problems that the computers encounter because they support both formats. If I'm wrong, I'll understand.
