In this approach, a low-power motion platform combines high-performance accelerometer and MCU technology to simplify sensor fusion. "This is typically a more limited solution in terms of features, but has some power and integration simplicity advantages," the Hillcrest spokeswoman said.
Other sensor hub competitors include Freescale Semiconductor, which launched the Xtrinsic fusion platform in 2012. Designed to exceed basic three-axis market requirements, the Xtrinsic integrates an onboard accelerometer with the ability to manage multiple external sensors.
When the Xtrinsic was launched, Freescale said it provides an ideal platform for making smarter system-level decisions by enabling complex calculations required for sensor fusion algorithms via interpreted sensing information and control, rather than simple raw data processing.
Hillcrest's design wins with China's Coolpad and Oppo are significant, considering the strengths of both brands in that country.
According to Counterpoint Technology Market Research, Coolpad ranked fourth in smartphone shipments to China in the first quarter, after Samsung, Lenovo, and Xiaomi.
Coolpad shipped more smartphones in China than Apple in the first quarter of 2014.
