Cortex A	Cortex R	Cortex M
Application processors.	Real time processors.	Microcontrollers.
Used in wide range of devices that have fully functional processors.	Used in critical systems where data interpretations is essential.	Designed for small devices and mixed signal processing.
High performance, high efficiency and high computational power.	High performance, real time and safe.	Low performance point, higher efficiency.
It runs at relatively high clock frequency.	It runs on high clock frequency.	It runs at slower clock speed.
It is connected to large amount of memory.	--	It is connected to less memory.
It handles large amount of applications and is capable of running complex operating system directly.	It is designed to handle fast changing data, and to be sufficiently responsive to handle data throughput without slowing down.	It is built into microcontroller with I/O lines and designed for small factor systems that rely on heavy digital input and output.
--	It is cost effective, requires low power and less physical area.	It requires less energy and has longer battery life.
--	--	It requires smaller code and it is easy to use.
Applications- Mobiles, telephones, tablets, laptops, etc	Applications- Medical Deices, Car systems.	Applications- Robotic systems, small consumer electronics.
