  • Patent number: 5394524
    Abstract: In a graphics subsystem, a highly interactive two-dimensional (2D) data stream and a computationally intensive three-dimensional (3D) data stream are processed concurrently in such a manner that processing of the 2D data stream is not held up by processing of the 3D data stream. A 3D geometry subsystem having a parallel pipeline architecture is used to process the 3D data stream, while a 2D subsystem concurrently processed the 2D data stream in parallel with the 3D subsystem. A reordering device couples the processed 2D and 3D data streams to a common raster subsystem. The reordering device, which contains an internal buffer, reorders any order-dependent elements of the 3D data stream appearing at the output of the 3D geometry subsystem in an order different from the order in which they were supplied to the input end.

  • Patent number: 5315701
    Abstract: The data processing system includes processing nodes and a graphics display device for processing a graphics data stream. The data processing system partitions a graphics data stream into a data segments or work groups for processing by the processing nodes. Next, the data segments are distributed for processing to the processing nodes. In response to receiving a data segment at a processing node, the data segment is processed to produce a processed data segment. The processed data segments are recombined into a processed graphics data stream. This processed graphics data stream is coupled to the graphics display device.
