D68000 FPGA core ?

Anyone seen or know anything about this ...

I have contacted them to see what their licensing policy is....

While I am clocking 32 MHz, I was looking at moving towards 64Mhz with the 68SEC000 CPU, but I think there will be bottlenecks in terms of SRAM & ROM access speeds which will be tricky to get beyond 32MHz.. Even so, being able to run internal instructions at superspeed would still be a huge gain, assuming the core can actually run at 32 MHz or faster..

There is also the LGPL licensed TG68 open core. https://opencores.org/project,tg68

I have seen that one, but it does not seem to have been updated in rather a long time ? I do not know if it is actually complete or not either..

Emailed from xlinix site as well, still no reply :roll:

Without trying to start another huge debate on this, It's a shame the Apollo guys wasn't more co-operative when we approached them like 2 years ago. They seem to be the only ones doing active CPU clones.
