Hillcrest develops MotionEngine Wear for IoT devices

However, the MotionEngine Wear firmware is completely processor and sensor agnostic, with Hillcrest maintaining an up-to-date library for all the major MEMS sensor makers and all the major microcontroller makers including Atmel (reportedly to be acquired by U.K.-based Dialogue Semiconductor), NXP, ST Microelectronics, and supporting designs using ARM Cortex-M, Cadence Tensilica Fusion DSP and Synopsys ARC EM. It is also OS agnostic, so it can be deployed when using platforms with Android, Android Wear, Tizen, WebOS and any RTOS.

"Wearables are adding more and more sensors, when most only had an accelerometer a few years ago," Lucien said. "And as more sensors are added, it becomes more difficult for OEMs to write their own software making MotionEngine Wear an increasingly attractive alternative."

MotionEngine Wear can run on any application processor or any auxiliary microcontroller or sensor hub, including ARM Cortex-M or digital-signal processors such as Cadence Tensilica Fusion DSP, and Synopsys ARC EM.

MotionEngine Wear automatically senses the activity state of the wearable such as stationary, walking, running, biking, in-vehicle, and can also be run on the application processor itself or on the separate sensor hub processor for more robust systems such as the Android SoC + Hub like SAM-G or any other sensor hub processor, including the Alcatel One-Touch Watch which uses a subset of MotionEngine Wear.
