Reaching the limits of low power design

As process technologies continue to shrink, and feature demands continue to increase, more and more capabilities are being pushed into smaller and smaller packages. But are we finally reaching the point where power density limitations make this trend no longer sustainable? What advanced techniques are in use today, and on the horizon, to address this? Are we limited only to hardware techniques, or can these power limitation issues be addressed with smarter software development? And how do we handle verification of these complex implementations? This paper explores possible methods for improving the ";power capacity"; of power sensitive designs.
