Well, the RPi offloads things like A/V codecs to dedicated hardware on
the die outside the CPU core, and Raspbian and the like run on the CPU
driving that hardware. The CPU can just as easily drive such dedicated
hardware if it's outside the RPi board altogether, e.g. crypto ASIC's.
Maybe Alvin already thought along such lines but erroneously selected
the Arduino platform to fill the ASIC role, rather than either
off-the-shelf ASIC's or an FPGA?
