FPGA Stack Brings Always-on, On-device AI In Edge Devices

always-on AI

Lattice Semiconductor’s improved sensAI stack accelerates deployment of always-on, on-device AI into a range of edge applications including mobile, smart home, smart city, smart factory, and smart car products.

Always-on, on-device, low-power, flexible artificial intelligence (AI) is increasingly a requirement in edge devices that are battery operated or have thermal constraints. The sensAI solutions from Lattice Semiconductor address this challenge with several improvements to support a variety of low-power, flexible system architectures for always-on, on-device AI. These improvements include improved accuracy, scalable performance, and ease-of-use, while still consuming only a few milliwatts of power.

Improved sensAI stack enables always-on, on-device AI revolution

Lattice Semiconductor unveiled expanded features of the company’s popular Lattice sensAI stack designed to speed time-to-market for developers of flexible machine learning inferencing in consumer and industrial IoT applications. Building on the ultra-low power (1 mW-1 W) focus of the sensAI stack, Lattice is releasing new IP cores, reference designs, demos and hardware development kits that provide scalable performance and power for always-on, on-device artificial intelligence (AI) applications, according to the announcement.

Updates to the sensAI stack include


• IP Cores – New CNN Compact Accelerator IP core for improved accuracy on iCE40 UltraPlus FPGA, and enhanced CNN Accelerator IP core for improved performance on ECP5 FPGAs
• Software Tools – Updated neural network compiler tool with improved ease-of-use and both Caffe and TensorFlow support for iCE40 UltraPlus FPGAs
• Reference Designs – New human presence detection and hand gesture recognition reference designs and demos
• Modular Hardware Platforms – New iCE40 UltraPlus development platforms including Himax HM01B0 UPduino Shield, and DPControl iCEVision Board
• Design Service Partners – New vehicle classification and package detection demos from sensAI Design Services Partners
