Variability increases as geometries shrink. Leakage power varies five to 10 times. Frequency varies about 30 percent.

Now we're looking at power in the rest of the platform. The CPU is in relatively good shape.

We need to design our systems to fit within this set of thermal envelopes.

We are really focused on minimizing energy per instruction. That's the new mantra.

It's kind of like how many angels can you fit on the head of a pin?

Not only were the platforms in the science fiction movies user-aware, they were self-aware, and that notion of self aware added to the excitement of those motion pictures and added a bit of trouble. In the end, HAL turned out to be too human like – that was the fatal flaw. The concept of self awareness can be a bit dangerous. This notion of turning against the user is fundamental to the plot line, but it doesn't have to be that way.
