A graphic rendering pipeline 1 has a number of different rendering units 2, 3 and receives fragments 4 for rendering. A renderer stated word cache 5 is used to store rendering state data to be used to configure the rendering units 2,3 when they render a fragment. Each rendering unit 2, 3 includes a functional block 10 which carries out a rendering operation on a received fragment and a renderer state word interface 11 that can be used to look up the required rendering state data from the renderer state word cache 5. Each fragment 4 is provided to the rendering pipeline 1 with fragment data 6 that indicates, inter alia, a fragment index 7, a renderer state word index 8, and other fragment data 9 that is necessary to render the fragment. When a rendering unit 2, 3 of the rendering pipeline 1 receives a fragment to be rendered, it firstly uses the renderer state word index 8 associated with the fragment 4 to look-up, using its renderer state word interface 11, the relevant rendering state data from the renderer state word cache 5. It then uses that rendering state data to configure its functional block 10, and then renders the fragment. |
