Abstract
A method includes storing a first/second set of biased exponents associated with a first/second plurality of input floating point data respectively in a memory. The first set of biased exponents defines a positive piecewise linear range associated with a positive piecewise linear approximation region of a function. The second set of biased exponents defines a negative piecewise linear range associated with a negative piecewise linear approximation region of the function. The positive/negative piecewise linear approximation regions include a first/second plurality of subregions respectively. Each subregion of the first and the second plurality of subregions includes at least one or more linear approximations. The method includes storing indices data for mapping each linear approximation with each subregion of the first and the second plurality of subregions to a unique index value. An offset and a slope for each of the unique index value are stored.
