ARM Architecture profiles

Application profile (ARMv7-A à e.g. Cortex-A8)

Memory management support (MMU)

Highest performance at low power

Influenced by multi-tasking OS system requirements

TrustZone and Jazelle-RCT for a safe, extensible system

Real-time profile (ARMv7-R à e.g. Cortex-R4)

Protected memory (MPU)

Low latency and predictability ‘real-time’ needs

Evolutionary path for traditional embedded business

Microcontroller profile (ARMv7-M à e.g. Cortex-M3)
