  • Apparatus and method for texture level of detail computation
    Patent number: 8487948
    Abstract: A graphic processing system to compute a texture level of detail. An embodiment of the graphic processing system includes a memory device, a driver, and level of detail computation logic. The memory device is configured to implement a first lookup table. The first lookup table is configured to provide a first level of detail component. The driver is configured to calculate a log value of a second level of detail component. The level of detail computation logic is coupled to the memory device and the driver. The level of detail computation logic is configured to compute a level of detail for a texture mapping operation based on the first level of detail component from the lookup table and the second level of detail component from the driver. Embodiments of the graphic processing system facilitate a simple hardware implementation using operations other than multiplication, square, and square root operations.

  • Coordinate computations for non-power of 2 texture maps
    Patent number: 8207980
    Abstract: A graphic processing system to compute a texture coordinate. An embodiment of the graphic processing system includes a memory device, a texture coordinate generator, and a display device. The memory device is configured to store a plurality of texture maps. The texture coordinate generator is coupled to the memory device. The texture coordinate generator is configured to compute a final texture coordinate using an arithmetic operation exclusive of a division operation. The display device is coupled to the texture coordinate generator. The display device is configured to display a representation of one of the plurality of texture maps according to the final texture coordinate. Embodiments of the graphic processing system facilitate a simple hardware implementation using operations other than division.
