Cadence Design Systems has announced that the FreeMotion Sensor Fusion and Context Awareness Libraries from Sensor Platforms (SPI) are being ported to the Cadence Tensilica HiFi Audio/Voice digital signal processing (DSP) core. This software is scheduled to be available in the second quarter of 2014.
The FreeMotion Library interprets sensor data to determine the position and orientation of the device and the context of the user. The library provides sensor fusion, the algorithmic technique of combining the outputs from two or more sensors, to record a common event so that the fused result better captures the event than any single input. This allows applications to get more reliable information from sensors and provides context awareness, which is a layer of algorithms on top of sensor fusion that interprets sensor data to deduce higher-level information. These algorithms determine a context even when users are not directly interfacing with their devices.
