The arm side of the beaglebone is certainly not impressive, but the PRU cores are potentially interesting for driving realtime hardware. It's what they are for. Of course they are not arm cores, they use their own instructions so one would have to write code for a TI proprietary core that only a small number of processors support. But it does mean you have dedicated cores designed for driving hardware without having to share resources with the main OS. Certainly the raw arm processing power of the Pi4 is easier to work with and more portable to other systems in the future. -- Len Sorensen
