Hi Peter Harris
I am using a Samsung Exynos 5244 processor which has A15 and A7 cores. When I run an application and get the power profiling, I see for a single constant frequency (say 1700MHz), the voltage varies between 0.913 V and 1.15V . Can you please explain, why this happens ?
Also, I want to keep the voltage constant for a single frequency. Is there any way to fix the voltage level to a single constant value for a particular frequency.
Thanks,
You are running your code on the chip or some kind of OS? If for example Linux (or Android on top of it), it is likely that the kernel modifies the core voltage in order to reduce power consumption.
