The cores are optimized for hard real-time and safety-critical applications. com. ) CPUs: Cortex-A5, Cortex-A7, Cortex-A32, Cortex-A34, Cortex-A35, Cortex-A53, Cortex-R5, Cortex-R8, Cortex-R52, Cortex-M0, Cortex-M0+, Cortex-M3, Cortex-M4, Cortex-M7, Cortex-M23, Cortex-M33 GPUs: Mali-G52 , Mali-G31 . Arm Cortex-M0 Processor Datasheet Datasheet Figure 1: Block diagram of the. The Cortex-M7 processor takes advantage of the same easy-to-use, C friendly programmer’s model and is 100% binary compatible with the existing Cortex-M processors and tools. Cortex-A Class processors. Design files. As well as the more common "A-profile" CPUs (which have MMUs and will run Linux) we also support the Cortex-M3 and Cortex-M4 "M-profile" CPUs (which are microcontrollers used in very embedded boards.
