Choosing Power-Saving Techniques


Engineers have come up with a long list of ways to save power in chip and system designs, but there are few rules to determine which approaches work best for any given design. There is widespread confusion about what techniques should be used where, which IP or subsystem is best, and how everything should be packaged together. The choices include everything from the proper level of clock and... » read more

DVFS On The Sidelines


Power reduction is one of the most important aspects of chip design these days, but not all power reduction techniques are used equally. Some that were once important are fading and dynamic voltage, and frequency scaling (DVFS) is one of them. What's changed, and will we see a resurgence in the future? What is it? DVFS has physics powerfully in its favor. As Vinod Viswanath, director of res... » read more
