Besides the main 64-bit A7 processor in the new iPhone 5s, Apple has included a dedicated motion co-processor called the M7. The chip powers many of the sensor technologies in the iPhone, such as the accelerometer, compass, and gyroscope in order to move the weight off of those technologies from the phone’s main chip. This, in turn, will make the new iPhone more efficient for both performance and battery life for the user.
Apple briefly explained some of the consumer-facing abilities of the M7 motion chip, highlighting that the chip could greatly enhance fitness apps such as those from Nike. But, just like with the new iPhone’s Touch ID fingerprint scanner, Apple’s ambitions for the M7 are greater than those discussed earlier this week. According to a source with knowledge of the chip’s development, Apple plans to tightly integrate the chip with its own Maps service in the coming years.
On its official website, Apple presents a brief teaser of what the M7 can do, highlighting a feature in the iPhone 5s (which was not discussed during the keynote presentation):
