The BeagleBone's CPU has a normal ARM processor and a pair of PRUs. (This is much like how the Cell processor had a normal Power processor alongside some Cell SPUs.) PRUs can control GPIO pins running your dedicated, hard-realtime code without an OS, and they can do it while Linux runs on the same chip.

- bsder 10y agoI'm well aware of the on-board PRU's. They are very cool. They also are very specific to the TI processors and lock you into using the Sitara's forevermore. Not so good if I have a product with volume. In addition, the PRU's had absymal documentation when I last checked. Fortunately, that seems to be changing.
