摘要： A method and system for validating documentation. The method includes presenting a status mechanism operable to initiate a change in status of a portion of documentation, receiving a request to change the status of the portion of documentation, changing the status of the portion of documentation based on the request, and notifying an owner of the request to change the status of a portion of documentation. The method further includes presenting the portion of documentation to the owner and updating the status based on receiving a request to change the status of the portion of documentation. The system and method facilitate keeping documentation up to date.

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.

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.
