Human Presence Detection

Lattice sensAI Reference Design

Add Human Presence detection (or any specific object of interest) to any Device – The human presence detection reference design enables systems to always search for the presence of a human via a CMOS image sensor. With an updated training model using the deep learning frameworks Caffe or Tensorflow, your AI systems can detect and locate any object of interest.

Optimized Power and Performance – The reference design enables a scalable systems design consuming between 1 mW and 0.85 W of power consumption depending on the chosen FPGA.

Production-priced, Space-efficient Design – The scalable inference engine fits inside of the iCE40 UltraPlus-5K FPGA and can be scaled up to fit in several devices of the ECP5 FPGA with increased performance.
