I haven't used both CPUs of these dual CPU systems yet. But in theory they should allow some quite nice division of tasks: The small CPU can handle the timing intensive application (maybe with some bare metal code). The second CPU can handle higher level control and communication. It would be interesting to implement something like that.

I have thought about this.  It's more hand-coding for the control loops, but it's traditional coding.  Not everyone thinks the eTPU/PowerPC architecture is as well-designed as I do - "Way too complicated!" is the feedback I get.
