sensor hub

A sensor hub is a microcontroller unit/coprocessor/DSP set that helps to integrate data from different sensors and process them.{{cite web|url=http://www.mobilitytechzone.com/topics/4g-wirelessevolution/articles/2013/05/13/337815-atmel-sensor-hub-mcu-helps-enhance-samsung-galaxy.htm |title=Atmel Sensor Hub MCU Helps Enhance Samsung Galaxy S4 User Experience, Battery Life |publisher=Mobilitytechzone.com |date=2013-05-13 |accessdate=2013-09-29}} This technology can help off-load these jobs from a product's main central processing unit, thus saving battery consumption{{cite web|url=http://news.mydrivers.com/1/275/275848.htm |title=iPhone 5S懂你"芯"：M7协处理器浅析-iPhone 5S, M7,协处理器,浅析-驱动之家 |publisher=News.mydrivers.com |date= |accessdate=2013-09-29}} and providing a performance improvement.{{cite web|url=http://www.atmel.com/products/touchsolutions/sensor_hub/default.aspx |title=Sensor Hub |publisher=Atmel.com |date= |accessdate=2013-09-29}}

Intel has the Intel Integrated Sensor Hub. Starting from Cherrytrail and Haswell, many Intel processors offers on package sensor hub. The Samsung Galaxy Note II is the first smart phone with a sensor hub, which was launched in 2012.

Examples

Some devices with Snapdragon 800 series chips, including HTC One (M8), Sony Xperia Z1, LG G2, etc., have a sensor hub, the Qualcomm Snapdragon Sensor Core,{{Cite web|url = http://www.qualcomm.com/snapdragon/features/sensors|title = Snapdragon Sensor Core | Qualcomm|date = 2013|accessdate = 16 July 2014|website = |publisher = |last = |first = }}

and all HiSilicon Kirin 920 devices have sensor hub embedded in the chipset with its successor Kirin 925 integrated an i3 chip with same function into it.{{Cite web |url=http://www.usdaycarejobs.com/huaweis-new-phablet-gets-an-iphone-5s-like-fingerprint-reader.html |title=Huawei's new phablet gets an iPhone 5s-like fingerprint reader | US Day Care Jobs |access-date=2014-09-04 |archive-date=2014-09-04 |archive-url=https://web.archive.org/web/20140904194419/http://www.usdaycarejobs.com/huaweis-new-phablet-gets-an-iphone-5s-like-fingerprint-reader.html |url-status=dead }} Some other devices that are not using these chips but with a sensor hub integrated are listed below:
