QuickLogic offers sensor hub for mobile devices
This allows sensors to be always-on and to be ready to sense when a phone has been picked up and to be switched on automatically, the company said.
The ArcticLink 3 S1 integrates a combination of hard logic and reprogrammable fabric. The Sensor Manager block communicates with multi-axis sensors such as accelerometers, magnetometers, gyroscopes, ambient light sensors, and pressure sensors, sampling and buffering multiple seconds of the sensor data. It is a microcoded state machine and features an I2C controller. The Flexible Fusion Engine (FFE) is intended to filter and interpret sensor data before sending information up the line to the host application processor. The FFE is a microcoded finite state machine plus microcontroller ALU for processing sensor data. When coupled with the FreeMotion software from Sensor Platforms this allows the delivery of such functions as: change detector, pedometer and background magnetometer diversity.
As well as the sensor hub IC QuickLogic provides a software tool for developers to define, simulate and map their algorithms to the FFE.
