Power Management from Smartphones to Data Centers
Power has become a first-class design constraint in computing platforms from the smartphone in your pocket to warehouse-scale computers in the cloud. Historically, semiconductor innovation has repeatedly provided more transistors (Moore’s Law) for roughly constant power per chip by scaling down supply voltage each generation. Unfortunately voltage scaling has ended due to stability limits and chip power densities are increasing each generation on a trajectory that outstrips improvements in the ability to dissipate heat.
