A voltage regulator really fast multi-core

Since the x86 CPU manufacturers have moved their center of gravity towards the Multi-core solutions instead of preferring the single frequency operation, we began to hear more and more consumption, efficiency and dissipation. Not by chance has been coined the term "Performance-per-Watt." The main objective is to provide the highest possible performance by keeping consumption under strict control: it is now applied to a variety of techniques which aim to reduce the frequency and voltage independently for each core, the full shutdown of non-core assets, gating and so on.

A student at Harvard University, Wonyoung Kim, however, found that it is possible to further improve the situation thanks to a new voltage regulator that can switch from one state to another very quickly. Kim has created a multi-core voltage regulator to be integrated on-chip that uses a technique called "fast-voltage scaling" which allows you to cut the power immediately to the components off dramatically increasing battery life in mobile devices and reducing consumption in desktop systems.

Kim did not speak of marketing, but has a patent to protect its technology.
