FPGA Designs with Optimized Logarithmic Arithmetic
Haohuan Fu, Oskar Mencer, Wayne W. Luk · IEEE Transactions on Computers · 2010
Using a general polynomial approximation approach, we present an arithmetic library generator for the logarithmic number system (LNS). The generator produces optimized LNS arithmetic libraries that improve significantly over previous LNS designs on area and latency. We also provide area cost estimation and bit-accurate simulation tools that facilitate comparison between LNS and floating-point designs.
