Abstract
A graphics system includes a graphics controller for rendering polygons with a minimum number of steps and registers. A host processor generates a display list that includes only the values necessary for rendering a primitive. The graphics controller includes a register file for receiving the display list either directly from the host processor or from system memory in which the host processor stored the display list. The graphics controller also includes logic to decode operational codes to ascertain which values from the register file must be used for rendering a primitive and which values can be skipped. Only the necessary values are transmitted to polygon and texture engines also included within the graphics processor.
