Abstract: An on-chip sensor hub fabricated on a chip with a main processor of a mobile device, and the mobile device, and a method for multi-sensor management on the mobile device. An on-chip sensor hub includes a co-processor and uses an inter-process communication interface. The co-processor and main processor of the mobile device are fabricated on the same chip and communicate with each other via the inter-process communication interface. The co-processor controls a plurality of sensors in the mobile device in accordance with requests issued from the main processor. The co-processor further collects and manages sensor data from the sensors to be processed by the main processor.
