Difference between revisions

Hello,

I'm very new at the community, I want to start working with the ARM cortex A15, while looking for the datasheet, I got the page ARM Information Center, where I found a LOT of information about the processor,

my question is about the different version of revision : r4p1, r3p3, r3p2...., what is the difference between them?

thank you

  • Hi and welcome!

    These are processor implementation revisions, similar to software revisions. A silicon vendor will implement a certain revision in their product.

    The first number is like the major release, and the second is the minor release. So, the very first implementation would be r0p0, then r0p1, then r1p0, r1p1...

    Differences between versions could be features, bug fixes, and other changes.

    In order for you to use the correct documentation from Infocenter, you need to see with the silicon vendor product datasheet (or ask them) which processor version they implemented in their product.

    Is that a bit clearer now?

  • Yea. This is very helpful. Thank you
