The Arm Cortex-R4 processor is the smallest deeply embedded real-time processor based on the Armv7-R architecture. The Cortex-R4 processor delivers . MPU interaction with memory system This section describes how to enable and disable the MPU. After you enable or disable the MPU, the pipeline must be. e.g., Cortex-A8) v7-R (Real-Time; e.g., Cortex-R4) v7-M (Microcontroller; e.g., The Cortex-M3 TRM also covers a number of implementation details not.

Jul 2, 8: It is similar to the A profile for applications processing but adds features which make it more fault tolerant and suitable for use in hard real-time and safety critical applications. A failure of such a system could lead to severe injury or loss of life.

Cores in this family implement the ARM Real-time R profile, which is one of three architecture profiles, the other two being the Application A profile implemented by the Cortex-A family and the Microcontroller M profile implemented by the Cortex-M family.
