• cortex-A15 instruction set and optimization ways on this platform?

    Dear,

    I am an greenhand developer on cortex-a15.

    now I need some specification as follows:

    where I can get the instruction set of cortex-A15?

    are there some documents about optimization technology on cortex-A15(image processing optimization)

    Thanks a lot.

  • De-merits in using Cortex A9 for single core processor

    Hi Experts,

    A8 is meant for single core and A9 is for multi-core based.

    Consider in case of SoC is build with single core of A9 and A8 how we could compare both in terms of some metrics/parameters like power/speed ?

  • Memory barrier (DSB, DMB). Does they guarantee writing data on cache to memory?

    Hi Experts,

    I'm reading white paper for ARMv7 and ARMv8.

    but when i reading cache part and memory re-ordering, i have silly questions.....

    Suppose there are below instructions..

     

    Core A:

         STR R0, [Msg]

         STR R1, [Something…
