摘要： A computing system has a graphics processor, a graphics memory, main memory, a bridge, and a central processing unit configured to process floating-point data of a first fixed size. An interconnect grid includes communication paths to link the graphics processor, the graphics memory, main memory, the bridge, and the central processing unit. A computing system component (e.g., the graphics processor or central processing unit) converts floating-point data to graphics floating-point data with a fixed size smaller than the fixed size of the floating-point data. The computing system passes the floating-point data and/or the graphics floating-point data over at least a portion of the interconnect grid. Alternately, the graphics processor may directly read and process previously compressed and stored graphics floating-point data.

摘要： Method and apparatus for graphics processing is described. More particularly, a graphics processing subsystem capable of multi-pass graphics data processing is described. The graphics processing subsystem includes a geometry processor and a fragment processor, where output from the fragment processor is input compatible with the geometry processor. Data produced in a pass through a graphics data-processing pipeline including the fragment processor and geometry processor may be used as an input to processing during a subsequent pass. Data read from a texture map may be used to define or modify data, including vertex data, being processed in the geometry processor or the fragment processor.

摘要： A processor for computer graphics calculations comprising an entire graphics engine in a single integrated circuit. The processor includes a transform mechanism adapted to compute transforms for the computer graphics calculations. The transform mechanism includes a transformation element adapted to compute transforms using a dot product operation. The transform mechanism of the processor also includes a perspective division element, a color unit for lighting calculations, a scaling element for multiplication operations, and a look-up table containing mathematical functions used by the computer graphics calculations. The processor also includes a raster unit coupled to the transform mechanism, a texture unit coupled to the raster unit, and a shader unit coupled to the texture unit.
