• voltage levels for dvfs
    Hello, i was wondering if the voltage levels for dvfs states are fixed at the design time. For example for Cortex A7 or A15. Is this information available? Thank you.
  • Why does the ARM A15 processor have so many DVFS levels ?
    For eg. the A15 on the Samsung Exynos 5422 has around 19 DVFS levels which varies frequencies from 200MHz to 2GHz.
