New type of accelerator design?

[bloodline]

I was wondering. Since there are now things for the Amiga such as the CFIDE68k, and the MiniMig was invented, how difficult would it be to have an accelerator the size of an A1200 trapdoor that had either a programmable chip or an AMD 64x2, which could emulate a very fast 68020 or 68040?
    I'm thinking of a board whose sole purpose is to allow memory expansion and this emulation. Nothing else, unless it would be convenient in the case of a programmable chip to also provide USB, SATA, etc.
    I'm also wondering if this emulation would run Amiga programs much faster than a real chip? I know in WinUAE it is quite fast!
    Any thoughts? Would this be possible? Would you own such a device? There must be some interest in Amiga if GVP has recently come out with new accelerators?

Thanks for your consideration,

The problem is that when you use a modern chip like one of the nice intel or AMD chips you can use all the support chips that are very easy to interface with them!

Look here: http://www.via.com.tw/en/initiatives/spearhead/pico-itx/

That is an entire modern computer (with USB, Audio, VGA and Ethernet) on a board smaller than an Amiga trapdoor accelerator (10cm x 7.2cm)!

Then you have to wonder what the point of using the A1200 is...

... until you add USB...

Exactly!

So, instead of building an accelerator based on a modern CPU... what you really want is an amiga USB keyboard... that idea has merit...

not that i care too much. neither for aros or mos or os4 alltogether. but if they ever succeed i will get one for sure.

You can use all three now... I can't really see how they could succeed any more that that?

Depending on accelerator design it could theoretically be possible to keep both CPUs on the bus, but don't expect anything Amigaish to support a 2nd CPU for SMP. You'd need to run a separate OS on the secondary CPU (similar to a WarpOS setup) and some elaborate method to make them communicate.

What would be nice is to have a re-distribushin of some 'old' accelerator card which was available back then! Are these boards still under patent/copyright? if not, then why can't they just be copied by some company (or a group of people) and re-sold. A pre-order model could be used to make sure no money gets lost.

Any old design is a total no go. Any design now must be RoSH, so any new electronics would be a redesign.
