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

  ß Memory management support (MMU)

  ß Highest performance at low power

  ß Influenced by multi-tasking OS system requirements

  ß TrustZone and Jazelle-RCT for a safe, extensible system

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

  ß Protected memory (MPU)

  ß Low latency and predictability ‘real-time’ needs

  ß Evolutionary path for traditional embedded business

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

  ß Lowest gate count entry point

  ß Deterministic and predictable behavior a key priority

  ß Deeply embedded use
