While the Internet of Things is growing at an incredible pace the chip manufacturers which are competing for this new market segment are running into problems when trying to design chips to add to appliances. There is a balance which needs to be found between processing power and energy savings, the goal is to design very inexpensive chips which can run on microWatts of power but still be incorporate networked communication and sensors. The new Cortex-M7 is a 32-bit processor which is directly competing with 8 and 16 bit microcontrollers which provide far less features but also consume far less power. Does a smart light bulb really need to have a 32bit chip in it or will a lower cost MCU provide everything that is needed for the light to function? Intel's Quark is in a similar position, the processing power it is capable of could be a huge overkill compared to what the IoT product actually needs. The Register has made a good observation in this article, perhaps the Cortex M0 paired with an M4 or M7 when the application requires the extra horsepower is a good way for ARM to go in. Meanwhile, Qualcomm's Snapdragon 600 has been adopted to run an OS to control robots so don't think this market is going to get any less confusing in the near future.
"The Internet of Things (IoT) is growing an estimated five times more quickly than the overall embedded processing market, so it's no wonder chip suppliers are flocking to fit out connected cars, home gateways, wearables and streetlights as quickly as they can."
