Commentary: Determining the cost of power

A funny thing happened on the way to the "everything-is-handheld" world of computing and communications: turns out Moore's Law doesn't apply to batteries. While transistor counts are still doubling roughly every 18 months, the same progress in battery life takes more than five years.

But power issues go beyond the battery. Problems relating to power consumption affect every system-on-chip (SoC) design at 90nm and below. Traditional tradeoffs between performance and area are compounded by the addition of power into the equation. High on-chip currents decrease the life and reliability of products, so reducing power has become a critical challenge for the nanotechnology era and one of the most important success factors for new SoC designs.
