I visited TI's Kilby labs a while back and they were doing all kinds of experiments with motors to reduce power consumption. It was fascinating, because you don't often think of semiconductor firms doing motor research... but low power needs are pushing the big players into those spaces
It's funny that at the mean time ARM is losing in power efficiency. The Samsung Exynos 5 is power hungry in both Cromebook and Nexus 5. The ARMy smartphones consume more power than the medfield phones. The ARM's arguments are always about the maximum performance and idle power consumption, while the others about both the full load performance and top power consumption.
@wsw1982. Watch out. You are in the wrong place. This is ARMTimes (aka EETimes) and you cant say anything bad about ARM. Even though the Exynos in your Chromebook is sucky and consumes about 10W, you cant say anything negative.
