Patent abstract

Mathematical functions are computed using a single hardware pipeline that performs polynomial approximation of second degree or higher. The single hardware pipeline includes multiple stages. Several data tables are used on the computations. The data tables are associated with a reciprocal, square root, exponential, or logarithm function. The data tables include data associated with implementing the associated function. The single hardware pipeline computes at least one of the functions associated with the data tables.
