Distributed Sensor Processing & Buffering

Connecting, bridging, managing, buffering and processing sensors with low power, small size FPGAs.

I/O Rich FPGAs - Lattice FPGAs offer multiple I/O banks, each capable of supporting independent voltage standards. Implement your bus expansion needs by using Lattice FPGA’s flexible I/Os.

Always-On Sensor Management - Enable that “Always-on” feature that you have been dreaming about by using Lattice’s low power, low cost FPGAs.

Distributed Heterogeneous Processing – With flexible I/Os, these small FPGAs can be placed around PCBs to enable direct connectivity to various sensors. Along with integrated DSPs, the same FPGAs can also provide sensor processing. Finally with additional integrated memory, the captured data can also be buffered prior to being sent to application processors. Together, these three blocks (flexible I/Os, integrated processing, and integrated memory) enable an optimized distributed heterogeneous processing (DHP) solution.

Block Diagram

Always-On Sensor Management

  • Localized processing or pre-processing next to sensors for quick responsiveness
  • Improve layout by routing only a single interface to application processor by combining multiple sensors

I/O Hub

  • I/O rich FPGAs with support for various standards such as, but not limited to, SPMI, I2C, SPI, UART, Soundwire, Slimbus, etc
  • Signal Aggregation to improve layout constraints caused by multiple signals
  • Flexible I/Os are able to be adjusted based on layout needs

Pedometer

  • Pedometer: Is your pedometer not power efficient? Lattice FPGAs enables your system to constantly monitor sensor activity while consuming very low power. Realize your Pedometer solution using Lattice FPGAs.
  • Context Awareness: Low power, low cost Lattice FPGAs can be used to create next generation context aware features in your device today.

Sensor Hub

  • Is the proliferation of sensors causing a I2C bus contention problem? Lattice FPGAs allow you to create dedicated I2C ports for those high bandwidth critical sensors.
  • Interface to the Application Processor using a lower power, higher bandwidth SPI interface
  • Poll sensors in low power while the Application Processor is in sleep mode. Enable customizable buffers, polling schemes based on your specific needs.
