Abstract
A graphics system includes a graphics processor for rendering graphics primitives with a display list. A host processor generates a display list which includes a command format for loading the display list into a register file. The graphics processor includes logic to encode and decode the command register to sequentially load the display list into the register file without a physical reference to the register being loaded. The command register may also be programmed to allow the graphics processor to randomly load the register file thereby shortening the processing of the display list and allowing the display list to be written during a burst cycle mode of bus operation.
