Abstract: A switching device in a network system for transferring data includes one or more source line cards, one or more destination line cards and a switching fabric coupled to the source line cards and the destination line cards to enable data communication between any source line card and destination line card. Each source line card includes a request generator to generate a request signal to be transmitted in order to obtain an authorization to transmit data. Each destination line card includes a grant generator to generate and send back a grant signal to the source line card in response to the request signal received at the destination line card to authorize the source line card to transmit a data cell to the destination line card.

Abstract: A pipelined reorder engine reorders data items received over a network on a per-source basis. Context memories correspond to each of the possible sources. The pipeline includes a plurality of pipeline stages that together simultaneously operate on the data items. The context memories are operatively coupled to the pipeline stages and store information relating to a state of reordering for each of the sources. The pipeline stages read from and update the context memories based on the source of the data item being processed.

Abstract: A computer-implemented method for generating three-dimensional images by reusing multisample memory. Pixels corresponding to a first section of the overall display are multisampled. The multisampled pixel values corresponding to the first section of the display are stored in a multisample memory. The final pixel values corresponding to the first section of the display are stored in a frame buffer. Thereupon, multisampling is performed on those pixels belonging to a second section of the overall display. The same multisample memory is reused to store the multisampled pixel values corresponding to the second section of the display. In other words, the same piece of multisample memory is shared between the first and second portions of the display, thereby minimizing the amount of multisample memory that is needed. The final pixel values corresponding to the second section of the display are stored in the frame buffer. This process is repeated until multisampling has been performed over the entire display area.

Abstract: A method and apparatus for efficiently managing texture memory in computer graphics systems is provided. Texture images are stored in discrete memory-aligned tiles to avoid fragmentation in the texture memory. Larger texture images are divided up into smaller tiles so that they will fit in any available tile region in texture memory. Small texture images usually fit into a single tile and therefore do not usually have to be divided up. Texture images that are larger than a tile region are split up into tile-sized images that are stored individually in any available tile region of texture memory. By dividing up the larger texture images this way, the texture memory is used more efficiently because any gaps that appear in the texture memory due to fragmentation may be filled by the tile-sized images.
