Motion Coprocessor for Android 4.4 KitKat

General Description

The Motion Coprocessor is an ultra-low power sensor hub to support all Android 4.4 KitKat-compliant sensors, providing a full solution of processing plus algorithm in one tiny and efficient package.

The Motion Coprocessor embeds the complete range of KitKat sensor features in hardware on a low-power coprocessor, allowing smart phone OEMs to support always-on context aware applications such as Google Now - without having to worry about power consumption.

The Motion Coprocessor offers a single solution for both enabling hardware and software for KitKat and «always-on» operation of the highest performance motion, context and location algorithms.

Compared to FLASH-based sensor hub microcontrollers (MCUs) with on-board floating point units (FPUs), the motion coprocessor operates at <1/10 power. It can routinely run over 140’000 floating point operations per second at ~200μAmps average current consumption at 1.8V.

The Motion Coprocessor accommodates up to 6 different sensor inputs and is the only sensor hub in the market that can run all the KitKat sensors simultaneously for under 200 μAmps.
