• why there are 4 cores per cluster in ARMV8 architecture

    Hi experts,

    I want to knows why there are 4 core cores per cluster in ARM big.Littte architecture?

    Is it possiable if we make more cores per cluster? if not, what is the limitation?

  • Does CCI-400 guarantees cache coherency between secure and non-secure worlds?

    Hi Experts,

    I'm developing some kind of Secure OS on A57/53 big.LITTLE SoC.
