Abstract :
The most important physical trend facing chip architects is the fact that on-chip wires are becoming much slower relative to logic as the on-chip devices shrink. The author points out that it will soon be impossible to maintain one global clock over the entire chip, and sending signals across a billion-transistor processor may require as many as 20 cycles
