so yes, then.

  It's kind of a middle ground, it looks more like a barebones MCU. RP2040's PIO is extremely limited with only 9 available instructions, this looks a bit more involved, but functionally it's very similar.

  The PRUs are simple single-issue in-order CPUs designed to make cycle-counting easy. They are more than an accidentally turing complete useful combination of a down-counter and shift-register. Don't get me wrong the RP2040 PIO is a very flexible, powerful peripheral for a sub-$1 MCU. A single PRU is probably larger than the whole RP2040.
