Sounds like the Parallax Propeller 1/2 as well.

It's a good model for MCU stuff. There were people pushing Chip Gracey (Parallax) to use RISC-V instead of his custom ISA when he designed the P2 a few years ago, but he chose to do his own thing. Which has made compiler development difficult.

This seems more on the RPI side rather than propeller, propeller was never a really good choice for production integration. This looks like it could hold its own in many contexts.
