Chuck Moore, creator of Forth, gives his annual Fireside Chat at Forth Day 2011 at Stanford. He talks about his multi-core GreenArrays chip design and demonstrates code running on it.
HN recommends it as a window into Moore's minimalist CPU design and the GA144 chip, despite the slow pace.

I was blown away by this 2011 video of Charles Moore talking about his CPU design and running code, talking about how the different nodes are creating the frequencies to produce the images you see on the projector - this video
The following two points are highly tangential and don't squarely answer your question; I'm just mentioning them as things to file away in case they turn out to be relevant. - [LINK] shows an experimental new CPU architecture which appears to be single-core but demonstrates interesting power savings and speedups by eschewing standard on-chip caching and building a smarter compiler. TL;DR closed-source compiler, but I think the people making the design are trying to make the architecture design/registers/overview/etc as open as practical/viable with free documentation etc. I'm not sure if there's a simulator for it. I'm very sure they're already taking on commercial customers, and getting access to it is likely to be not overly nontrivial. (I realize you're not likely to need one just yet, but "can't access at all" makes for something much less interesting to file away.) - Forth, Inc. makes the GA144, a 144-core microcontroller that natively runs Forth (and will NOT comfortably run transpiled <any other language here>). At one point a production company was making evaluation boards. this video is a (1hr long, somewhat slow-paced) presentation that provides a good overview of the GA144. I half wonder whether I'm looking at a chip designed by people who don't understand SMP when I watch this, but I also think that it's possible that the brutal simplicity that Forth (and Chuck Moore) applies to everything means that I'm really staring at the raw complexity of SMP here. I've read tha
There's some on youtube in the manufacturer's channel, Greenarray. this video Also maybe try the designer's site, Chuck Moore. Google Colorforth.
