EFFICIENT FUNCTION INTERPOLATION USING SIMD VECTOR PERMUTE FUNCTIONALITY

A system, method, and computer program product are provided for generating display data. The data processing system loads coefficient values corresponding to a behavior of a selected function in pre-defined ranges of input data. The data processing system then determines, responsive to items of input data, the range of input data in which the selected function is to be estimated. The data processing system then selects, through the use of a vector permute function, the coefficient values, and evaluates an index function at the each of the items of input data. It then estimates the value of the selected function through parallel mathematical operations on the items of input data, the selected coefficient values, and the values of the index function, and, responsive to the one or more values of the selected function, generates display data.
