Tri-core hub packs 3-axis accelerometer, 3-axis gyroscope

Of course, Bosch begs to differ with this characterisation as does PNI Sensor Corp., which offer both a single-chip solution, sans the sensors, plus board-level solutions that combine Bosch sensors with PNI's sensor hub.

"PNI's device is a sensor hub with no sensors, and doesn't seem to have a built-in framework. This normally would translate into customers having a long ramp-up time with bringing up the device, optimising power and then getting to a point where they can start developing their own value-added software. And with an ARC core, PNI's customers will find themselves with limited tools and ecosystems," Khemani indicated.

The software stack spans from user applications, to the hardware abstraction layer (HAL) all the ways to the framework engine, motion algorithms and custom user code on the Cortex M0 to power management, real-time-operating system (RTOS) and drivers for each sensor. (Source: InvenSense)

Of course it's up to the designer and engineer to choose between the pros and cons of the Invensense, Bosch and PNI solutions to the growing sensor hub problem, now that smartphones, Internet of Things (IoT) and wearables are all studded with sensors whose raw output has to be fused to make sense of all that data.

The Bosch and PNI devices are available whereas the Invensense solution will begin sampling later in 1H15.
