Abstract
A method implements fixed-point polynomials in hardware logic. In an embodiment the method comprises distributing a defined error bound for the whole polynomial between operators in a data-flow graph for the polynomial and optimizing each operator to satisfy the part of the error bound allocated to that operator. The distribution of errors between operators is updated in an iterative process until a stop condition (such as a maximum number of iterations) is reached.
