Is there model specific register that has a raw data of current or power of arm core?
For example, in case of the arm FPGA there is SYS_CFGCTRL register which is specialized for containing info of current, voltage , temperature of instructions.
I want to measure the instruction wise power on arm core.
I believe there should be specialized register to save the log of power or current.
Moved thread to Developer Platforms forum.
There is nothing built into the CPU that will give this. You may get some instrumentation from system peripherals if these are provided by the chipset manufacturer (which is what you get with the SYS_CFGCTRL - that's an additional peripheral in the Arm development board - but it's not standard).Also worth noting that it's unlikely that any system level power monitoring will be accurate at the instruction level.
