Abstract
A graphics system includes a graphics processor for rendering graphics primitives with a list of display parameters. A host processor generates a display list which includes a XY address for rendering the graphics primitives. A graphics processor which includes an arbitration logic device enables the graphics processor to temporarily arbitrate shared resources to dissimilar graphics drawing engines. The arbitration logic allows data from the dissimilar drawing engines to be prioritized, depending on the configuration of the underlying computer system, for accessing shared resources.
