Paper Abstract

Direct table-based methods are frequently proposed for the implementation of low-precision evaluation of functions. We examine and compare the real implementation on current FPGAs of two methods, the single table and the bipartite table, introduced in the literature. We focus on the sine/cosine functions, input and output sizes in {8,...,12} and on LUT-based FPGAs and especially on the Virtex device family from Xilinx.
