A method and apparatus (201) for general-purpose genera- tion of digital mathematical functions in connection with a com- puter processor enabling computation of such functions as ex- ponential, logarithmic, hyperbolic and trigonometric functions, as well as numerous special-purpose engineering functions. The invention employs compact look-up tables (206m 207, 208) ac- cessed by look-up techniques and value interpolation to deter- mine values not found in the tables. In specific embodiments specific techniques are employed for table generation and value interpolation to attain results at desired levels of speed, preci- sion, economy, and reliability. Applications include alternatives to conventional hardware multipliers and numerical processors. Individual embodiments may be realized either directly in hard- ware or in software. Multiple embodiments may be realized as software or hardware function libraries. Coupled multiple embodiments may be realized as general-purpose hardware or software mathematical processors.
