The "emulation" would be very very similar in concept to 68040.library or 68060.library. In fact, it's the exact same concept, but will probably need to trap and emulate more instructions than those libraries did. If they put it on the board and not in a file on disk, I sure hope they use a nice FLASH that can easily be rewritten with bugfixes and performance improvements.

> If the Coldfire doesn't trap 32-bit muls and mulu instructions

Does it fail, or are you "if-ing" about hypothetical stuff? Id think that in trapping an instruction it doesn't have implemented, it wouldn't say anything about  afew certain functions like muls or mulu being non-implemented but not allowed to trap...

Does it not just say "I don't implement that instruction, I don't care what it is, just trap it." ???

I didn't realize that they had changes somewhat the results of certain instructions. That can make it more difficult than just being able to trap everything. But I doubt it's impossible. Come on, we've got the Amiga background, a tradition of doing the unnecessary, the bizarre, and the nigh-impossible.

No, it may not be easy, but if we all wanted to take the easy route we'd all be Windows users right now, wouldn't we?
