  • Supported by Arm Corstone-320, a reference design with a unified toolchain and the extensive Ethos-U ecosystem.

Benefits

• The Arm Ethos-U85 is the highest performance implementation of the Arm Ethos-U NPU. It enables enhanced edge AI processing with support for transformer-based models and delivers 20% more energy efficiency than previous generations of Ethos. The key characteristics of Ethos-U85 include:
  • Scalable performance – 256 GOP/s up to 4 TOPs at 1 GHz
    • Scales from 128 to 2048 MACs
  • Further reduced energy consumption – 20% lower than previous Ethos-U NPUs
  • Native support for transformer-based networks
• Ethos-U85 targets numerous different applications with use in high-performance Arm Cortex-A or low-power embedded devices based on Arm Cortex-M.
