A further innovation
If you are a proud owner of an iPhone you have purchased a device which is in someway much more sensitive than any human being ever can be. And it's not the incredible SIRI I'm talking about. iPhone's sensors know all about your movements, your finger, the distance between your ear and the device, your actual location, and even the brightness of the environment.
Your iPhone forms a liaison with you but it's an arranged marriage, it's a childless marriage, it's a miscegenation, and Apple hopes that it will not get a broken marriage. And if you are an Apple freak it's even a same-sex marriage.
Neither our brain nor any single processor can execute more than one task at a time.
So the central processing unit (abbreviation CPU) of your mobile has a painful task when measuring your movements all day long. That's the reason why Apple introduced to M7 Motion processor .
Think of it like this:
Every time the CEO (the A7) is focused on a task and needs help from his assistant (the M7) because the proud owner again jumps for joy while viewing Apple's Keynote, he sends a request to get motion data. Then he can refocus on actions depending on the devices motion.
The 64-Bit architecture of the A7 main processor in cooperation with the M7 Motion processor results in an awesome performance of the new iPhone 5S and the iPad Air.
Thanks for your attention.
