Though I'm sure this is valuable in certain instances, thinking about many embedded designs today, is the CPU/micro really the energy hog in these systems?
We're building an EEG headband with bone-conduction speaker so in order of power, our speaker/sounder and LEDs are orders of magnitude more expensive than our microcontroller.
In anything with a screen, that screen is going to suck all the juice, then your radios, etc. etc.
I'm sure there are very specific use-cases that a more energy efficient CPU will make a difference, but I struggle to think of anything that has a human interface where the CPU is the bottleneck, though I could be completely wrong.
