What is differene between cortex A, Cortex M and Cortex R series of ARM?

Q: I want to ask what is differene between A, R and M series of ARM microcontroller?

A： just add my QQ（1677970115）friend，I'll send u some docs.

Q: Kindly also suggest me a good book to start learning ARM microcontroller?

A: I' start with K60(Cortex-M4).

Q: Which complier is best for practical purpose?

A; I think IAR Embedded Workbench for ARM is simple for u.

Hi,

first of all, you'd better to investigate the following link:

Design, verify and program Arm Cortex-A, Cortex-R and Cortex-M processors

If you want to learn a microcontroller, you should choose Cortex-M.

'M' stands for Microcontroller.

By the way, what do you mean by the word of the embedded linux?

If it means the uCLinux, the Cortex-M version of it will be available.

If it means so called true Linux, you should choose Cortex-A because MMU is mandatory.

Cortex-A and Cortex-R have almost the same architecture with an exception of whether the MMU exists or not.

Cotex-M and Cortex-A are definitely different.

Best regaeds,
