Abstract
The performance of some chips (e.g., VLSI processors) may be increased by running the internal circuits at higher clock rates, but use of a higher clock rate is limited by the heat-dissipation ability of the chip's package. Apparatus and a method is described for estimating the total heat accumulated for dissipation at any given time. For the periods that the chip is idle, the clock rate is decreased to reduce heat generation. The heat saved while the chip is idling is available for use later to increase the clock rate above normal, provided that the total heat generated does not exceed the heat-dissipation capacity of the package.
