How to compute CPU power consumption
If you're mapping a given executable and you have access to more information about the CPU then you may be able to use some equations from frequency scaling to get a power profile.

For instance, the power consumption of a processor is estimated by:

$$ P = C * V^2 * F $$

where P is power, C is the capacitance being switched per clock cycle, V is voltage, and F is the processor frequency (cycles per second).
