power measurement on StratixIII

hello,

I want to measure the power dissipated on both stratix III processor Core and I/Os. for my experiment I use the MaxII device and the power 7segment display to display the power consumption.

My goal is to measure the (power or current) that costs each instruction like (add, mul ,nope, nor, or ...)

the problem is, when I make an infinite loop with one of the instructions I want to measure, I don't get any significant results, like if all the power drawn by each instructions is the same for all the instructions.

Can someone help me to find a way to develop a model in which we have all the instructions and their corresponding power consumption.

thx for your attention;
