Abstract : Since the Xerox Sigma 5 computer being used by the Materials Research Laboratory at the University of Illinois is primarily used for numerical computation, and since the evaluation of basic transcendental functions is a major part of many computations, it has been proposed that the hardware evaluation of these functions would lead to both faster and more accurate calculations. This report contains a basic design for a hardware function evaluation processor as well as the results of detailed simulations which make time and accuracy comparisons between hardware and software evaluation possible. The information presented here should provide some answers concerning the feasibility of building a hardware processor to evaluate numerical functions. (Author)
