Re: Nueron / NuOS (ColdFire based project)

I've had a few folk ask me if my chipset design would be useful to this project.  I've decided on answering them all at once:

If I felt that it was close enough to completion, it probably would be yes.

But that is a big if, shoot, the linebuffer system was borked only a few weeks ago in a live test to humerous results.

95% of the changes from Coldfire to 68k would be invisible to applications, but on-target for the OS.  The Coldfire handles supervisor-mode differently, its memory systems slightly different, etc.

And the 5% difference is actually less than the difference in instructions between the 68030 and 68060.

Everything you've mentioned relates to how the OS works on the chip, not the software.  The software doesn't know nor care of the addressing modes available, it cares about getting data to or from an address and the OS handles that.

So, in short, AOS would need to be rewritten, but the software wouldn't for the most part.
