Human Presence Detection AI Demo

Lattice sensAI Demo

Scalable Human Presence Detection – This demo uses artificial intelligence (AI) to implement a human presence detection algorithm. FPGAs have flexible parallel data processing ability, making them more power efficient at such tasks compared to a microprocessor.

Always-on, Local Intelligence Improves Security – Bringing AI to the network edge is challenging, but it also offers tremendous opportunity. Designing AI into an iCE40 UltraPlus or ECP5 FPGA instead of cloud-based resources can dramatically reduce power consumption, limiting or even eliminating network bandwidth and latency while accelerating response time. Local processing improves system robustness and security.

Scalable Multi-engine CNN Across Two FPGA Families – The Lattice inference engine with CNN architecture is able to fit into the iCE40 UltraPlus and several devices of the ECP5 FPGA Family.
