If you own an iPhone or an iPad, then you probably have heard of the motion coprocessor. This small but powerful chip is an essential component of Apple’s M-series and is responsible for gathering and processing sensor data from integrated accelerometers, gyroscopes, and compasses.
First introduced in 2013, the M-series motion coprocessor’s primary function is to take the burden of processing sensor data off the central processing unit (CPU) of the device. This feature helps reduce power consumption and allows for the efficient operation of the device.
The first iteration of the motion coprocessor was the M7, which was introduced in the iPhone 5S in 2013. This chip made use of an ARM Cortex-M3 core and was manufactured by NXP. It was then followed by the M8, which came with built-in barometers and was released in 2014.
If you are interested in the technical details, then you would be interested to know that the M7 and M8 motion coprocessors both feature an LPC18A1-based NXP LPC1800 microcontroller. However, the naming and packaging conventions of the M-series motion coprocessor are Apple-specific, making it unique to the brand.
