  • Reduced power matched filter using precomputation
    Patent number: 6366938
    Abstract: A technique for correlating a sequence of signal sample values with a predetermined digital code to produce correlation values for shifts in the sequence of signal sample values relative to the predetermined digital code is disclosed. The technique is realized by combining subgroups of the signal sample values in the sequence to form sets of precombinations, and then selecting one precombination from each set of precombinations to provide a plurality of selected precombinations. The plurality of selected precombinations are then added or subtracted to produce a correlation value corresponding to a shift in the sequence of signal sample values.

  • Method for adaptive polygon rendering with fast operation speed of interpolation
    Patent number: 6008815
    Abstract: In a method of polygon rendering, the coordinate and color spans of each polygon triangle are evaluated whether they are above or equal to a predetermined threshold value. A first bit resolution is applied to the polygon rendering, when the coordinate and color spans are above or equal to the predetermined threshold value. A second bit resolution lower than the first bit resolution is applied to the polygon rendering, when the coordinate and color spans are below the predetermined threshold value.
