I'd suggest a different name to avoid confusion with this thing.
Some people have been calling it the N68070. That should be enough to avoid confusion with the existing 68070.

Actually I miss the point of recreating a completely new (?) RISC core to have it run/emulate/whatever 68k code.
1. It's not emulation. FPGAs give you the chance to build the real thing.
2. The main reason behind the N68070 is to integrate it with SuperAGA into one chip, giving cost and speed benefits over a 68060.

There are lots of low cost, high speed available CPUs (well, most of em x86), why not use on of them? While you're at it, add one of the off-the-shelf mobos that don't cost a fortune and are wickedly fast. Obviously you end up where Amithlon started - so I'd rather see a PCIe (or PCI if need be) board sporting an original AGA chipset or a nice vamped up Minimig/Natami/... chipset to get 100% compatibility. Most work (UAE) is already done.
How many f**king times have I got to answer this question. The NatAmi is called such because it is a NATive AMIga. You can have your emulation fun elsewhere, myself (and many others) want beefed up classic hardware, that's what the NatAmi offers. No x86, PPC, ARM, etc... or at least not as the main CPU.

as I said before.. I enjoy my A2000/060 as it is fun and makes me young again, but come on people, unless you make a 'new' Amiga OS run on x86 forget it ! (just finish aros and then add some 1000 features it is currently lacking... ok ?)
Then run AROS and leave the NatAmi to the people who want it... ok?

I tried to give some positive feedback, but it is just showing the gulf between his ambitions and his capabilities.
The document is just a rough draft, a sketch of where they'd like to go. If you can help them with technical suggestions (as you did on the EAB thread) then that is the positive feedback you are looking for in vain.

He optimistically suggests 200Mhz speed... Something as complex as a 68k CPU is never going to get even 20Hmz real speed on an FPGA... I'd be surprised if that to be honest...
Who said it would be on a FPGA? When they are designing it, yes. When they are manufacturing it a structured ASIC is much more likely, so let me ask you this, is 200MHz out of the question on a reasonably priced structured ASIC (like one of the Altera HardCopy series)?

Hmmm... I've not got to read about that 68070 thing but... I did read about the fact that Freescale seems to offer custom-made processor solutions where the buyer specifies the functions he / she wants to see added over the standard feature-set. As I understood it, you could take a 'standard' Coldfire processor and ask for adding instructions, say... the missing instructions that were available on the 68060 creating a more compatible Coldfire processor. And while you're at it, why not throw in some extra features that could make your special system just that little quicker ;-).
But then.. I could be wrong :-S.
amiga_3k, it's a decent idea, but AFAIK Freescale don't let you modify the Coldfire core, but just build functions around it, so the issues with certain processor functions would still exist.
@all
As I've mentioned, the document is a rough draft. The Natami60 will be released without the N68070, there is plenty of time for discussion about how best to construct the N68070 without interfering with the Natami60 release. If you want to see the N68070 be the best CPU it can be and you have some 68k ASM knowledge then share your ideas with the Natami team.
