Numerical function generators using decision diagrams for discrete functions

Proceedings of the 18th International Workshop on Post-Binary ULSI Systems May 20, 2009, Naha, Okinawa, Japan.This publication is a work of the U.S. Government as defined in Title 17, United States Code, Section 101. As such, it is in the public domain, and under the provisions of Title 17, United States Code, Section 105, may not be copyrighted.This paper introduces design methods for numeric function generators (NFGs) using decision diagrams. NFGs are hardware accelerators to compute values of numeric functions such as trigonometric, logarithmic, square root, and reciprocal functions..
