ABSTRACT:
A method for selecting a set of parameters from a parameter space of a contemplated implementation of a pipelined processor for configuring the processor to generate an output word in response to each of a set of input words. The method includes determining a mapping between each set of parameters in the parameter space and the area of an integrated circuit implementation of the processor, and searching the parameter space to select a preferred set of the parameters that minimizes the area of the integrated circuit implementation subject to the constraints that each of the input word and the output word has specified format and that the preferred set of the parameters results in no more than a specified maximum error between the function of each of the input values and the approximation of the function of said each of the input values.
