Endian Issues; Figure 4-1. Big-Endian Mode - Motorola MVME5100 Programmer's Reference Manual

Endian Issues

The MVME5100 series supports both Little and Big-Endian software.
Because the PowerPC processor is inherently big endian, and PCI is
inherently Little-Endian, it is easy to misinterpret the processing scheme.
For that reason, provisions have been made to accommodate the handling
of endian issues within the MVME5100. The following figures show how
the MVME5100 series handles the endian issue in Big-Endian and Little-
Endian modes:
