High performance at affordable power

Regardless of what chip a team is designing, energy efficiency is probably one of the most important criteria. Achieving high performance at affordable power (and therefore, cost) is the overall system goal across a whole range of products that serve the home, entertainment, scientific, and commercial-enterprise segments of the information technology industry. The selection of articles in this issue of IEEE Micro will bring some of the latest innovations and ideas in energy efficiency to our readers´ attention, and thereby foster further thinking and research to improve upon current design practices.
