Arm has taken the wraps off of its Cortex-M52, an AI-optimized design for the IoT, with the chip now the smallest to feature Arm’s Helium technology. Due to arrive in 2024, Arm claims the Cortex-M52 achieves a 3x improvement in DSP (digital signal processor) processing power, and a 6x increase in machine learning (ML) workloads, compared to the older Cortex-M33 design. While the size of the M55 is 23% less than the M33, Helium was the main focus of the announcement – stressing how Helium enables designs that do not need a dedicated neural processing unit (NPU), as they can now make do with the native Helium functions in the M55. The technology is M-Profile Vector Extension (MVE) for the…
