PNI's Sentral sensor fusion hub is an IC for motion processing in mobile devices. It's designed for the offloading of sensor management and fusion work from host CPUs, thereby helping to reduce power usage.
The Sentral sensor fusion hub is the first hub designed specifically to manage sensor outputs on a low-power integrated circuit, making 9-axis motion sensing outputs both super-precise and practical to implement. Carrying top-of-the-line sensor fusion algorithms on an extremely low-power integrated circuit, Sentral eliminates the need for complex sensor configurations, calibrations and algorithm development. Further, it dramatically reduces power usage, offloading sensor fusion work from less efficient host CPUs or sensor CPUs onto an ultra low-power IC tailor-made for sensor optimization.
It is compatible with Android and Windows 8-based mobile products, and has a stated accuracy of 2° rms (root mean square).
Being a mobile-oriented product, the company emphasises power efficiency, claiming "the Sentral IC is ultra low power and consumes less than 10% of the power used by other CPUs performing the task of sensor fusion".
