Unique Sensor Hub Technologies

The S2 Gesture and Context Sensor Hub solution is based on the ArcticLink 3 S2 CSSP Sensor Hub platform, and contains a number of PSB technologies, including Communication Manager, Flexible Fusion Engine, and Sensor Manager.

System Architecture

The device autonomously samples and manages data from multiple sensors found in smartphone and wearable devices. This off-the-shelf solution enables OEMs to immediately integrate best-in-class context awareness and sensor management into their devices quickly.

The S2 Gesture and Context Sensor Hub Catalog CSSP is the ultra-low power sensor hub solution that delivers contexts and gestures in ~150µW, enabling OEMs and software developers to unleash new applications and use cases previously thought unattainable.

OS Support

The ArcticLink 3 S2 CSSP Sensor Hub is fully compatible with the Android OS and RTOS-based systems. QuickLogic provides standard Android driver libraries to allow for quick integration into an OEM system.

Communication Manager
  • Communicates with host applications processor/MCU through hard-wired SPI interface
Second Generation Flexible Fusion Engine (patent pending)
  • CISC-based ALU core for optimal combination of processing performance and power consumption
  • In-system reconfigurable for use in different context and applications
  • Four times the computational performance of previous generation
  • Four times the on-board algorithm capacity of previous generation
Sensor Manager
  • Autonomous initialization, sampling, and calibration of sensors through hard-wire I2C Master eliminates AP/MCU load and lessens overhead
  • 8KB of sensor data memory – support for up to 2000 individual time-stamped events
  • Compatible with all major inertial sensor manufacturers; see our QVL
