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.
The latest Arm Cortex CPUs are all based on the Armv8 CPU Architecture. Our architecture is continually evolving, providing new features and enhancements.
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.
