for those of us not willing to write a fucking CPU

There's insane maniacs who've written fucking CPUs in CSS, Minecraft, and Conway's game of life, among many other environments not intended for writing fucking CPUs.

Can't some insane maniac simply write a fucking CPU for FPGAs and release it as open source?

Plenty of insane maniacs have released lots of more useless stuff as open source, why not this?

(Using insane maniac as a compliment here; the world would be a much more boring and unenjoyable place without insane maniacs willing to waste their time making it a better or at least more interesting place.)

My fucking CPU comment was not that serious. The projects we were doing were just that. I have a notebook full of diagrams that I understand less and less every year.

It was just a bit shitty that the CPU part wasn’t included with the chip itself. IIRC the nicer ones had hardware CPUs/CPU cores anyway.

I meant it more as “hey I need to do this simple task, better write a processor real quick” which is not convenient. I’m almost certain there are dozens of FOSS RISC cores that could be burned to all of Xilinx’s FPGAs. It’s theoretically hardware agnostic but these are super popular parts.

The FPGA itself is just the chip. You can find them pre-installed in development boards though, but these are more expensive. But at least they might of a microprocessor if that's what you want.

And if you're fed up with Xilinx, check out Lattice semiconductors. They have a somewhat more open ecosystem

Thank you Sir/Maam, a better day was had here due to this...
