He's been proposing a method called asyncronous logic where there's no clock signal being distributed and regulating every part of the chip. The article doesn't give many technical details (greatly needed) but Sutherland, now doing research for Sun, is telling that significant breakthroughs have been made recently to make this technology viable for mass production. It is estimated that 15% of a chip's circuitry is dedicated to distributing the clock signal and as much as 20% percent of the power is consumed by the clock. This is indeed intriguing; what unit will replace the familiar megahertz?"
