Many processors I have programmed were Big Endians. With the addition of Freescale Kinetis (an ARM Cortex M4) and DSC in MCU10.2, I have a daily mixture with Big Endian (S08, ColdFire, …) and Little Endian (DSC and Kinetis).

The term “endian” is described nicely in the IEN 137 written 1980 by Danny Cohen:
“ON HOLY WARS AND A PLEA FOR PEACE“.

Well, this is maybe a too simplistic answer, but I think it has some truth. An embedded system programmer cares a lot about the memory of his system, and so do I. My post on flash programming was the aspect of permanently programming the memory. This one is is about RAM and Flash.
