CNN accuracy with flexible milliwatt FPGA solutions; New reference designs for human presence and hand gesture recognition with scalable performance/power

  • New CNN Compact Accelerator IP for iCE40 UltraPlus FPGAs with support for 16-bit and 1-bit quantization for improved performance, power, and accuracy tradeoffs
  • Enhancement to CNN Accelerator IP for ECP5 FPGAs with up to 2x increase in DRAM memory bandwidth, for improved performance in smaller devices
  • New hardware platforms, reference designs, and demos showcase scalable performance and power optimized for always-on, on-device AI applications

PORTLAND, OR – September 25, 2018 – Lattice Semiconductor Corporation (NASDAQ: LSCC) today 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.

“Flexible, low-power, always-on, on-device AI is increasingly a requirement in edge devices that are battery operated or have thermal constraints. The new features of the sensAI stack are optimized to address this challenge, delivering improved accuracy, scalable performance, and ease-of-use, while still consuming only a few milliwatts of power,” said Deepak Boppana, Senior Director, Product and Segment Marketing, Lattice Semiconductor. “With these enhancements, sensAI solutions can now support a variety of low-power, flexible system architectures for always-on, on-device AI.”

Examples of the architectural choices that sensAI solutions enable include:

  • Stand-alone iCE40 UltraPlus / ECP5 FPGA based always-on, integrated solutions, with latency, security, and form factor benefits.
  • Solutions utilizing iCE40 UltraPlus as an always-on processor that detects keyphrases or objects, and wakes-up a high performance AP SoC / ASIC for further analytics only when required, reducing overall system power consumption.
  • Solutions utilizing the scalable performance/power benefits of ECP5 for neural network acceleration, along with IO flexibility to seamlessly interface to on-board legacy devices including sensors and low-end MCUs for system control.

Updates to the sensAI stack include:

The Lattice sensAI partner eco-system continues to expand worldwide with new design service and IP partners focused on enabling smart home, smart factory, smart city, and smart car applications. “Lattice’s low power, small size FPGAs and neural network IP cores and tools, will significantly accelerate adoption of artificial intelligence at the edge,” said Amit Vashi, Chief Operating Officer, Softnautics, a sensAI Design Services partner. “With our expertise in machine learning, we are proud to be working closely with Lattice to enable sensAI solution deployments as evident by our jointly developed vehicle classification demo using ECP5 FPGAs”.
