The Arm Cortex-M55 processor is Arm's most AI-capable Cortex-M processor and the first to feature Arm Helium vector processing technology. It brings energy-efficient digital signal processing (DSP) and machine learning (ML) capabilities to the Cortex-M family. With the Cortex-M55 processor, developers can take advantage of the ease-of-use of Cortex-M, a single toolchain, optimized software libraries, and an industry-leading embedded ecosystem. The processor allows the integration of differentiating AI techniques, while staying within the system cost and energy constraints of battery powered IoT devices.
