  • Apparatus for performing a division operation, especially for three-dimensional graphics
    Patent number: 6161120
    Abstract: The present invention relates to arithmetical computing devices, and especially to a division operation in three-dimensional (3D) graphics. A division f(a,b)=a/b is calculated by an integrated division circuit. In order to decrease the chip area and calculation time needed, the bit width of the divider and the dividend is reduced by preprocessing. Firstly, the scaling factor is searched in basis of the divider. Then both the divider and divident are scaled by the single scaling factor. Division is then done with these shrunk bit vectors.
