Abstract: We propose relaxing the restricted form of faithful rounding used in prior 32-bit Logarithmic Number System (LNS) implementations. Unrestricted faithful rounding yields a three- to six-fold savings in VLSI ROM size (or four- to six- fold savings in F GPA table size) with only modest increase in error. This can be acceptable for the DSP and multimedia applications in which the non-standard LNS is a candidate for adoption. Such applications are cost sensitive, and the tremendous cost reduction of the LNS model proposed here should argue very favourably for its adoption.
