I appreciate the intro, motivation and comparison to the PIO of the RP2040/2350. How would this compare to the (considerably older, slower, but more flexible) Parallax P8X32A ("Propeller")?
- t-3 7mo agoThe Propeller 2 would be an interesting comparison as well, with it's own smart pins playing a similar role.
- crest 7mo agoIIRC the Propeller is an eight thread barrel CPU with the same number of pipeline stages. So it "retires" just one instruction per cycle. All PIO state machines can run every cycle so they should be considered very small CPU cores. You can think of them as channel I/O co-processors for a microcontroller instead of a mainframe.
