Abstract
A graphics system includes a graphics processor for rendering graphics primitives with a list of display parameters. A host processor generates from a first clock domain a display list which includes poly parameter data for rendering the graphics primitives. A graphics processor which includes internal fetch and store unit stores and processes the polygon parameter data in a second clock domain different from the first clock domain. To ensure the complete processing of polygon data from the first clock domain in the second clock domain, the graphics processor includes a polygon data tracking logic for tracking the flow of the polygon data in the graphics processor. The polygon data tracking logic includes an up/down counter which up counts polygon data fetched in the graphics processor and down counts the polygon data when the polygon data is processed in the graphics processor.
