PRU-> programmable real time unit BBB-> BeagleBone Black The BBB has an extra dual core processor that runs at 200Mhz. It is interesting because it is like the processor they teach you about in your intro to computer architecture classes, every instruction is a single cycle instruction. Since it is a co-processor(not running an OS but controllable from the BBB's OS) and execution of instructions is deterministic, it is a good choice for running hard real time code.
