  • Combined floating-point logic core and frame buffer
    Patent number: 6760033
    Abstract: A method and apparatus for graphical processing. A logic core to perform pixel fragment manipulation and processing is instantiated on a single substrate with one or more memory units. The memory units are dynamically segmentable into frame buffer and texture memory. Because the logic core is on the same substrate as the memory units, the bandwidth between the core and the memory is greatly increased.

  • Apparatus and method for sharing antialiasing memory across multiple displays
    Patent number: 6756978
    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.
