Speech Title: Divide and Concquire: Floating-Point Arithmetic Algorithms Based on Taylor-Series Expansion
Abstract: This invited talk presents our research findings on efficient floating-point algorithms for computations such as division, exponentiation, square root, inverse square root, and logarithms, all leveraging the Taylor series expansion. In this work, methods for mantissa region division and mantissa region conversion were developed. Additionally, we examine the trade-offs between the number of additions, subtractions, and multiplications, as well as the Look-Up Table (LUT) size in hardware, to identify the most suitable algorithm for engineering designs and to develop the optimal hardware device.
