I'm unfamiliar with the "minion cores" reference in your comment. Is this the same things as this RISCv architecture? https://www.lowrisc.org/docs/minion-v0.4/

  That's what I was referring to. The PRUs in a TI AM335X (like the BeagleBone) are similar. Basically real time capable microcontrollers that share memory with the mainstream CPU that is probably running Linux. Allows for interesting use cases, like high speed data in or out to drive LED displays, sample signals, generate audio, etc.

    Thanks, this is really interesting. Might you have any other links or resources on this you could share? Cheers.
