Abstract

This paper discusses an efficient interpolation method for nonlinear function generation. Based on this, a 24 bit VLSI cell, capable of computing the (1) square root, (2) reciprocal, (3) sine/cosine, and (4) arctangent functions, is presented for single precision floating-point applications. A 53 bit version, suitable for double precision computations, is also presented. Finally, an extension of the method to the two dimensional nonlinear functions is briefly addressed
