Ultra-low Power Sensor Hubs

Available as Catalog or Fully-customizable Solutions, Ideal for Always-on Context Awareness

Always-on Context Awareness

Smartphone & wearable OEMs and mobile application developers envision a near-term future where our mobile devices, even when idle, are always aware of our activities and surroundings. Called Always-on Context Awareness, this is delivered through the fusion of data from a number of sensors in a device.

QuickLogic ArcticLink® 3 S1 Ultra-Low Power Sensor Hub Overview

OEM Sensor Hub Requirements

QuickLogic’s ArcticLink 3 S1 Ultra-low Power Sensor Hub (ULPSH) is the first device to meet the power thresholds and support the sensor processing functions required to make always-on sensing in smartphones, wearables and tablets a mainstream reality. Supporting run-time re-configurablity, the ULPSH supports the use of multiple sensor algorithms for different contexts (walking, running, in a car, on an elevator, phone in pocket/hand, etc...).

Power Consumption

Less than 2% of system battery life

OEMs desire always-on context awareness, but only at less than 2% of system battery life – QuickLogic’s ArcticLink 3 S1 enables that

Sensor Manager
  • Microcoded state machine and multi-second data buffer for programmable sensor management
  • Low power I²C controller with dynamic pull-ups to reduce wasted I/O power
  • QuickLogic maintains a comprehensive qualified vendor list

Integrated Development Environment

Software, sensor and sensor algorithm engineers can customize the functionality of the ArcticLink 3 S1 through QuickLogic’s Integrated Development Environment (IDE) and Development Board. The IDE, called the Flexible Fusion Engine Algorithm Tool (FFEAT), enables engineers to:

  • Quickly and easily develop code and algorithms
  • Compile to the ArcticLink 3 S1 ultra-low power sensor hub architecture
  • Simulate results accurate to the clock cycle
  • Perform real-time hardware debug

 

FFEAT is specifically tailored for engineers familiar with sensor algorithms and software, these tools speed time-to-market by providing an abstraction layer between the sensor algorithms and software (typically expressed in a C-like language) and the hardware implementation. The IDE and Development boards supports algorithm development and real-time board-level debugging, and can be used to port internally-developed or properly-licensed 3rd party sensor algorithms to the sensor hub.

Sensor Development Boards

QuickLogic’s Sensor Hub Development Boards complement FFEAT by providing a proven hardware platform for sensor hub hardware development, testing, and debugging. The boards were designed with platform flexibility in mind, supporting connectivity to host systems in a variety of ways, including PC via USB and directly to a DragonBoard by Qualcomm. The boards also have flexible connectors that can be used to connect 3rd party sensor boards for easy sensor bring-up, algorithm development and hardware debug.

 

The ArcticLink 3 S1 is available in multiple configurations

ArcticLink 3 S1

The standard ArcticLink 3 S1 CSSP contains all the necessary system blocks for customers to port their code into. This flexible design allows customers to choose 1 or multiple algorithms that best suit their use cases and needs. QuickLogic's Integrated Design Environment provides a hardware and software environment for porting OEM- or 3rd party-developed algorithms into the sensor hub.
