VLIW was trying to do the same, by analyzing the code with the compiler and produce wide instructions, that can feed many parallel execution units...
But compilers weren't really as good in doing it as they predicted, being one of the reasons for Intels EPIC to fail.

Transmeta was doing the same by dynamically translate x86 into VLIW code and the Tegra CPUs do the same for ARM to VLIW.

According to the video, they now might try to put more and more silicon and software, AI and ML, and so on to that task ...

Sound like an overcomplicated mess to me to be honest and is probably nothing that will do anything for us in terms of an FPGA accelerator.
(WinUAE would automatically take advantage of this, when it ever happens)

For us it would probably be enough to concentrate on a more straight forward approach: modern RISC cores already do some parallelism in form of out-of-oder and superscalar execution. They can already execute 2 instructions at once (or more if you take FPU and SIMD into account).

The other step forward would be to give the AmigaOS the ability to take advantage of multiple processors ... some work has done already on AROS (clean way) some other by the Vampire team (hidden and "dirty") via multithreading on the 68080.

Thanks. This allowed me to do a better research and i found this :

But current cpus have several execution units already, so it's unclear to me where the benefit of dispatching to several cores could be...

The Dip 68000 cpu fits nicely and case will close (objective completed ). The A500 vampire a500 also works in the a600 but the case wont close which i think everyone knew it wouldnt. (our accel will be able to fit with the case closed and that was the primary objective. I will release files once its 100%
Hi Kipper, I was just wondering on the status of the A600 adaptor and it's release, or if you are waiting for the accelerator to be done.

I am keen to get it tested out with a terriblefire and maybe some other A500 accessories to see how it goes. and maybe re-jigging the layout to fit my setup better.

Oh, and nice work on the new board!

Hi,
Thanks for the kind words. I can't speak for Mike but i think there should be an update pretty soon, he has been able to make some progress. i will give it a couple of weeks before i show anything on the final adapter. I did modify it a bit so that you can use it with a 3D printed rail that will lock it into place. I have to send it in for one more build to confirm, but i think its good.

The SMD500 is giving me a hard time atm, pretty well all functions work but having stability issues. Agnus', Gotek/OSD, sound, composite,SVID/RGB etc works fine.

The A1k board is at similar level
