Apple motion coprocessors

The Apple M7 (codename Oscar), M8, and M9 are motion coprocessors used by Apple Inc. in their mobile devices. Their function is to collect sensor data from integrated accelerometers, gyroscopes and compasses and offload the collecting and processing of sensor data from the main central processing unit (CPU). The M7 was introduced in September 2013 with the iPhone 5S and the updated version, M8 was introduced in September 2014 with the iPhone 6 and also processes data from the barometer that is included in the iPhone 6 and iPad Air 2. September 2015 brought the M9 motion coprocessor embedded within the A9 chip found in the iPhone 6S, iPhone 6S Plus, and within the A9X chip found in the iPad Pro.

Chipworks found that the M7 most likely is a NXP LPC1800 based microcontroller called LPC18A1. It uses an ARM Cortex-M3 core with a customised packaging and naming scheme indicating that it is for an Apple customized part. iFixit have identified the M8 in the iPhone 6 to be an NXP device with a very similar name, the LPC18B1.

M7 (railcar)

The M7 is an electric multiple unit railroad car built by Bombardier, with delivery beginning in 2002, used by the MTA on the Long Island Rail Road (M7) and Metro-North Railroad (M7A). The M7 replaced the M1 railcars, which had previously provided electric service on these lines. The M7 are powered from an electric third rail.

Cars are arranged as married pairs, where each car contains a complete set of controls for an engineer, conductor, or brakeman. However, the 'B' Cars (denoted by odd-numbered car designations) contain a handicapped accessible restroom, which is larger than the restroom provided on the M1 and M3 railcars and designed to accommodate a wheelchair, as well as an attendant and/or service animal (such as a guide dog, hearing dog or service dog) accompanying the passenger. The enlarged bathroom reduces the number of seats in the car.

The M7 was built as two separate, but similar models owing to the different electrical and signaling systems on the LIRR and Metro-North. The M7 has AC traction motors and can accelerate more quickly from a standing stop than previous MU sets. The two different cars also contain different door-closing lights; the LIRR (Long Island Rail Road) has small red button-sized closing-lights, while Metro-North has white light strips. Unlike the M7s, the M7As have pads behind each headrest. On the M7, the seats face toward the center, but on the M7As, the seats face away from the center.
