• Building Ne10 Library With ArmCompiler 5 on ARM Cortex A9

    Hello everyone,

    I am having difficulties on compiling Ne10 library with ArmCompiler 5. As I understand, Ne10 library requries a GNU compiler, or ArmCompiler 6 which is more GNU like, however currently we are using ARM Compiler 5 in our project.

    Is there…

  • 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 ?
