[DailyTech] Fast Voltage Regulator Could Add to Battery Life

Current systems-on-a-chip and mobile computer CPUs offer some clever strategies to reduce power consumption and extend the battery life of increasingly powerful mobile electronics. One strategy is to shut off unused cores. And for multi-core and single-core designs alike, typically there's slow regulation of core voltage based on usage.

However, Harvard School of Engineering and Applied Sciences Ph.D candidate Wonyoung Kim [profile] believes that current generation methods were falling short of their true potential. He proposes that voltage be regulated much faster, dropping from microsecond regulation to regulation on a nanosecond scale.
This would help load line calibration and overclocking....

Looks interesting, I don't see this having a huge impact on power consumption though, but I guess every extra minute of battery life is great and it adds up.

Basically fine tune things even farther? Wouldn't that create more expensive parts? Though I would be all for it, a greener earth. Green is good for ya! hahaha

Yes - but the best way of improving battery life on portable devices is to use larger batteries, which would fail in the marketplace because everyone wants small.

Batteries are the most expensive way of providing power, on a per kW basis, but then, people want there portable devices to be portable and free of cords.

Well yes, that's just like adding a larger gas tank to a car. The goal isn't having more fuel, it's being more fuel efficient. Less heat, ect....
