Hi Ankit, You will need extraordinary accuracy and precision in power measurements to achieve that. Assuming that a quad core processor dissipates 100 W at 3G, that's 8nW per op. Since it's so small, it will likely be out-swamped by OS jitter, not to mention the kind (stability of voltage, frequency) of power supply we usually get in India. So, IMHO measuring anything "at the wall" is likely to be unreliable. However, low power operation in software is a really nice idea. You could try lesswatts.org. These guys are trying to minimize the power consumption by reducing the polling frequency of their device drivers etc. That seems to be a more fruitful venture, at least in the short term. But hey, many great ideas were laughed off as crazy initially. I'll be glad to eat my words if you can succeed. All the best. And do keep me posted. -- Rohit Garg http://rpg-314.blogspot.com/ Senior Undergraduate Department of Physics Indian Institute of Technology Bombay
