It has been shown that a 32-bit logarithmic arithmetic unit can operate faster than, and maintain the accuracy of, a 32-bit floating point unit [J. N. Coleman, E. I. Chester, April 1999]. It uses the logarithmic number system (LNS), in which a real number is represented as a fixed-point logarithm. In this paper we investigate the implementation of three fast affine projection (FAP) algorithms using LNS. We propose a simplified conjugate gradient FAP (SCGFAP) algorithm. We show that the 32-bit or 20-bit LNS implementation of the CGFAP and the SCGFAP algorithm are superior to those of the classical FAP algorithm. (14 References).
