  • Method and system for performing fast division using non linear interpolation
    Patent number: 6321245
    Abstract: The present invention discloses a method and a system for performing fast division using non linear interpolation. A storage stores x-axis and y-axis coordinates (X0, Y0) of a plurality of non uniform interpolation points, and x-axis and y-axis coordinates (&Dgr;X, &Dgr;Y) representing the differences between two successive points of the plurality of non uniform interpolation points is used. The plurality of non uniform interpolation points is selected such that the x-axis difference (&Dgr;X) is a power n of 2 in the form of (&Dgr;X=2n), with n being an integer. Upon reception of an input operand X, the storage selects and outputs a set of coordinates (X0, &Dgr;Y, n, Y0) associated to the input operand.
