Design of a VLSI circuit for on-line evaluation of several elementary functions using their Taylor expansions

ISBN: 0818634928International audienceThe authors present a new modular architecture for the online evaluation of power series. It can be used to quickly compute any function that can be approximated by the first terms of its Taylor expansion (i.e., most math functions). For trigonometric functions, the method matches Cordic-like methods and leads to more regular architectures. The authors also present a VLSI implementation of this architecture
