Abstract
A method and apparatus matches one or more clock speeds used in, or used by, a graphics accelerator so as to match graphics processing requirements to the speed of the clock source or sources. Clock speed is adjusted under software control to match current requirements. Power is conserved by reducing clock speeds from unnecessarily high rates to a rate that can satisfy current display mode settings and other graphics processing demands.
