Arm Unveils Its Most Compact Ai-capable Cortex-m Cpu

Arm has rolled out its smallest and most power-efficient 32-bit CPU core yet based on its Helium technology — the Cortex-M52. This CPU core is specifically designed to bring machine learning out of the cloud and into battery-powered IoT devices, providing a more than 5.6X uplift in performance for AI inference over its predecessors without additional power, silicon area, and cost. The M52 can be used for predictive maintenance, intelligent motor control, power management, keyword detection, gesture detection, and sensor fusion. It is a potential future substitute for the Cortex-M3, -M33, and -M4.
