1. A method of generating motion data comprising;
- receiving a gyroscope data from a gyroscope sensor;
performing integration using the gyroscope data and generating an integrated gyroscope data using a first processor;
receiving a data from one or more sensors, other than the gyroscope sensor; and
performing sensor fusion using the integrated gyroscope data and the data to generate motion data using at least one second processor.

Abstract
A method includes generating motion data by receiving a gyroscope data from a gyroscope sensor, performing integration using the gyroscope data and generating an integrated gyroscope data using a first processor. The method further includes receiving a data from one or more sensors, other than the gyroscope sensor, and performing sensor fusion using the integrated gyroscope data and the data to generate motion data using a second processor.
