The answer to your question depends on whether you are measuring power on real hardware or on a simulator. If you are measuring it on real hardware, you can write a microbenchmark consisting of many instances of the instruction that you want to profile. For ex:

_asm_{

add
add
add
...
add
add

}

Then you can divide the total energy and get energy/instruction.

If you are measuring this in a simulator, it should be much easier, but the answer would depend on the simulator that you are using.
