Tooling for the RPI PIO design is probably a bit more accessible than the TI PRU situation. I'd say its not really a miss - more of a necessity given bennies' proclivity towards open/available tools. Getting access to architecture details of the TI PRU would necessitate an NDA, would it not? |

Nope. All the information is right in the publicly available architecture manuals. However, you don't need to copy the PRUs, per se. All this can be done with RISC-V.
The important parts are deterministic execution, the register file sideload between paired processors, and, possibly, single cycle instruction execution. None of these are precluded by using RISC-V.
And, given how large his PIO stuff is, I'd argue it would be better to do this with RISC-V.
