Enhancing AI Performance for IoT Endpoint Devices

The new Arm Cortex-M55 processor brings endpoint artificial intelligence (AI) to billions. It’s Arm’s most AI-capable Cortex-M processor and the first to feature Arm Helium vector processing technology for enhanced, energy-efficient digital signal processing (DSP) and machine learning (ML) performance. The Cortex-M55 offers an easy way to implement AI for IoT with the ease-of-use of Cortex-M, a single toolchain, optimized software libraries, and an industry-leading embedded ecosystem. 

Features and Benefits
Improve ML and DSP Performance

Delivers up to 15x ML performance improvement and up to 5x signal processing performance uplift compared to existing Cortex-M processors.

Accelerate Time to Market

The Corstone-300 reference design offers the fastest, most secure way to incorporate the Cortex-M55 into a system-on-chip (SoC).

Simplify Software Development

Single developer toolchain supported by a broad ecosystem of software, tools, libraries, and resources.

Unlock the Benefits of AI with this Best-in-Class Solution

The combination of world-class hardware IP, easy-to-use tools, open-source software, and a leading ecosystem means the Ethos-U55 microNPU is transforming the future of small embedded and IoT devices. The Ethos-U55 microNPU is a component of a wider solution that includes the following key components to enable the next generation of AI devices:
