Clockless Chips
iarkin writes "TechReview is running a very interesting
article about clockless chips.
Clockless, or asynchronous, chips work very much faster and consume less power than their synchronous equivalents (Intel hade some experiments on these chips back in -97, the results showed that the asynchronous chips were three times faster and consumed only half the power)."
Async processing is a very old idea. The problem is that designing the logic for it is a far greater chore than for regular chips. CPU designers are simply not good enough to do it well yet.
