Type to enter text M ot i o n Co p r o C e s s o r SENtral™ Motion Coprocessor A powerfully freeing way to do sensor fusion on mobile devices. For unparalleled sensor fusion that consumes only 1% as much power as other processors. SENtral is a powerfully freeing way of doing sensor fusion. TM SENtral saves power. With top-ofthe-line embedded 9-axis sensor fusion algorithms, SENtral is an extremely lowpower motion coprocessor that completely offloads all motion sensor management and fusion work from your application processor thus saving you loads of power and a ton of headaches. Because it’s an ultra low-power chip tailor-made for motion sensor fusion, it fuses and continuously auto-calibrates the sensors for always-on requirements. All at a small fraction of the power of even a low power microcontroller sensor hub. In fact SENtral draws less than 1% of the power of 9-axis sensor fusion running on a Cortex M0 processor running less robust fusion algorithms without continuous auto-calibration. It moves 9-axis sensor fusion work off the application processor or hub processor onto an ultra low-power coprocessor that’s 100 times more power efficient, consuming less than 100 µA. Essential to the always-on requirements of motion sensors in mobile devices and the low power requirements of wearable devices. SENtral runs “best-in-class” 9axis sensor fusion with 2 degrees of accuracy. Using continous autocalibration technology, it polls individual sensors, integrating, fusing and filtering their data with patented Kalman filter algorithms. SENtral uses much faster sampling rates to deliver output that is lightening quick, accurate and immune to magnetic interference. Works with any sensor from any manufacturer. The SENtral motion coprocessor makes it practical because it supports virtually all gyroscopes, accelerometers and magnetic sensors from virtually any vendor. It allows you the control and flexibility you need. Sensor fusion that won’t hold you up. For many customers, working out the subtleties of sensor integration, signal enhancement, calibration, magnetic interference, sensor drift and power consumption has proven to be more difficult than first thought. It’s time consuming work that can delay product releases. Made with real world expertise. SENtral’s 9-axis sensor fusion technology is custom engineered by PNI Sensor, a leading expert in high end sensor fusion, and is built on a tailor-made ultra low-power coprocessor from EM Microelectronic, experts in producing ultra-low power microelectronic components.
