The STM32 chip has hardware quadrature decoders. These are a set of
flip-flops and counters that exist on the

Hey Chris,
AFAIK, the Pi has better HDMI support compared to the Beagle but then it was
designed more for multimedia. The Beagle PRUs have the advantage that they
have access to some of the Beagle Processor RAM. That gives them a bit of an
