Arm launches AI chip for IoT devices

Source: ArmArm has launched the Cortex-M55, an artificial intelligence (AI) processor based on the Armv8.1-M architecture with Arm Helium vector processing technology for significantly enhanced, energy-efficient digital signal processing and machine learning (ML).

The Cortex-M55 delivers up to a 15x uplift in ML performance and a 5x uplift in DSP performance, with greater efficiency, compared to previous Cortex-M generations.

The Softbank-owned chipmaker has also introduced the Arm Ethos-U55 neural processing unit (NPU), the first microNPU for Cortex-M that is designed to deliver a combined 480x leap in ML performance to microcontrollers.

“Enabling AI everywhere requires device makers and developers to deliver machine learning locally on billions, and ultimately trillions of devices,” said Dipti Vachani, Senior Vice President and General Manager, Automotive and IoT Line of Business at Arm.

“With these additions to our AI platform, no device is left behind as on-device ML on the tiniest devices will be the new normal, unleashing the potential of AI securely across a vast range of life-changing applications,” she added.

The Internet of Things (IoT) and AI are two of the hottest technologies in recent years. Combine these with the superfast 5G and smaller, cost-sensitive devices can be smarter and more capable while benefiting from greater privacy and reliability due to less reliance on the cloud or internet.

By delivering this intelligence on microcontrollers designed securely from the ground up, Arm is reducing silicon and development costs and speeding up time to market for product manufacturers looking to efficiently enhance DSP and ML capabilities on-device.
