Yes, I had something like this in mind. However, IIRC the PIOs can only operate as fast as the ARM cores, correct? So, if my understanding is right, a large chunk of clock cycles would be wasted waiting for instructions and data to arrive over the serial link itself rather than actually executing them. Not to mention, the core on the other end of the link would probably want some data back, and that would take even more clock cycles to send over.I would start with a PIO-based UART-style connection for transferring 32-bits, that is '32N1' rather than '8N1', get that working and start building up from there. It won't be fast but it's a start. I have no idea how close you will get to what you hope to achieve but you'll never know until you try it.
For more than two chips I would use the same mechanism but use something more like a token ring.
I wonder if there is a solution to that specific problem. Ideas, anyone?
