Document on difference between Cortex-A / -R / -M

Hello Pravincham,

chrisshore has written a nice document about the differences between the architectures of the Cortex processors: https://community.arm.com/processors/b/blog/posts/navigating-the-cortex-maze

You can also check-out Arm's website that gives an overview here: Processors - Arm

Hope this helps,

Christopher

For a more detailed view the official technical specification for the processor families is the Arm Architecture Manual which similarly exists in A/R and M variants:

Arm Information Center

HTH,
Pete

Thanks for mentioning that, Chris.

You can find a set of three follow-up documents which go into each of the three families in a little more detail:

Armv7-A - Power to the People

Armv7-R - Hidden Power

Armv6-M vs Armv7-M - Unpacking the Microcontrollers

Hope this helps.

Chris
