Multi-core voltage regulator (MCVR) to prolong battery life

Posted on Wednesday, March 16 2011 @ 09:30:22 CET by

TG Daily reports Hardvard graduate student WonYoung Kim developed an on-chip, Multi Core Voltage Regulator (MCVR) device, that promises to enhance the energy efficiency of mobile devices.
"If you're just looking at photos, you don't need to power the audio processor or the HD video processor."

So, in an effort to combat this growing problem and get more devices on board with energy-efficient multi-tasking, Kim has developed an on-chip, Multi Core Voltage Regulator (MCVR) device that, in mere nano-seconds, adjusts power levels to meet a processor chip's demands. 

Unlike the bulky, slow voltage regulators that are found on circuit boards, this MCVR is attached directly to a processor at each of its cores and can make lightning-fast adjustments to increase or decrease power as needed.
