Abstract:
1. An apparatus, comprising: a core cell configured to approximate a non-linear function applied to an input comprising a first order fraction and at least three successive higher order fractions, comprising: an offset generator configured to respond to said first order fraction to create a base value and to create each member of an offset collection comprising an offset value corresponding to each of said successive higher order fractions; and a shifted-input adder configured for shifted-input adding of a base value, based upon said offset collection, and based upon said higher order fractions to create an approximate value of said non-linear function applied to said input, further comprising: a shift-converter configured to receive said successive higher order fraction and said corresponding offset value to create a shift-result, for each of said successive higher order fractions; and said shifted adder configured for adding said base value and, for each of said successive higher order fractions, said shift result, to create said approximate value.
