AI Innovation for Edge and Endpoint Devices

Build low cost, highly efficient AI solutions in a wide range of embedded devices. The Ethos-U65 NPU maintains the power efficiency of the Arm Ethos-U55, while extending its applicability to Arm Cortex-A, Cortex-R and Neoverse-based systems and at the same time delivers twice the on-device machine learning (ML) performance.

Features and Benefits

Extending Performance and Efficiency

Unlock new vision and voice use cases in minimum area with 2x performance uplift (over Ethos-U55) and reach 1 TOP/s in 0.6mm2(in 16nm).

Flexible Integration

Build low-cost, highly efficient systems with rich OS and DRAM support in Cortex-A systems and on BareMetal or RTOS SRAM/FLASH systems on Cortex-M, with the highly successful Ethos-U architecture.

Unified Software and Tools

Develop, deploy, and debug endpoint AI applications faster using a common toolchain across Arm Cortex and Ethos-U processors.

Enhanced Design

Supports popular networks with extended operator support, provides wider AXI interfaces, and improves reliability with ECC added into internal RAMs.

What Arm Partners Are Saying

"The Ethos-U65 maintains the MCU-class power efficiency and architectural benefits of the Ethos-U55, while extending its applicability to higher performance Cortex-A-based system-on-chip (SoC)s."

Ron Martino, Senior Vice President and General Manager, Edge Processing Business, NXP Semiconductors.
