Arm architecture ensures better security, wide compatibility, high performance, and energy efficiency. Our central processor unit (CPU) architecture comes in three varieties optimized for different use cases: A-Profile for rich applications, , R-Profile for Real-time, and M-Profile for microcontrollers.
CPU Architecture defines what a CPU must do when software runs on it. All Arm-based CPU designs are built on the same architecture, ensuring software compatibility while enabling market or usage-specific innovation. This compatibility ensures partner success, increasing customer confidence and market uptake.
Armv8.1-M is the latest M-Profile architecture and it includes Arm Helium technology, the M-Profile Vector Extension (MVE) for the Arm Cortex-M series. Helium delivers a significant performance uplift for machine learning (ML) and digital signal processing (DSP) applications.
Optimized for Rich Applications and High-Performance Operating Systems
A-Profile is used in complex compute applications including servers, mobile phones, automotive head units and IoT gateways.
Optimized for Real-Time, High-Performance Applications
R-Profile is used where real-time or deterministic response is required, such as safety-critical applications. Use cases include medical equipment and transport, specifically in vehicle steering, braking and signalling functions.
Optimized for Discrete Processing and Microcontrollers
M-Profile is used where energy efficiency, power conservation, and size are key. It is especially suitable for invisible and deeply-embedded chips, such as smart goods. IoT devices are a key application of M-Profile CPUs, used in small sensors, communication modules, and smart home products.
