SENtral

Motion Coprocessor

General Description

The SENtral

Motion Coprocessor is a

custom integrated circuit that makes it easy
to quickly incorporate, optimize and operate
multiple

motion

sensors

on

mobile

consumer electronics devices. SENtral
employs and manages a user-specified
3-axis magnetometer, 3–axis accelerometer,
and 3–axis gyroscope to provide reliable
motion tracking, and accurate heading and
orientation data. SENtral gathers data from
the individual sensors, then integrates and
fuses this data using PNI’s proprietary
Kalman filtering and heuristic algorithms.

By offloading the sensor fusion and
interface from a dedicated sensor hub MCU
or the host CPU to SENtral, overall power
requirements are dramatically lowered and
processing power is opened up for other
uses.

These advantages make SENtral the ideal
choice for mobile and consumer electronics
devices

desiring

ultra-lower

power

consumption and best-in-class sensor fusion.
