The Residue Logarithmic Number System: Theory and Implementation

M.G. Arnold
17th IEEE Symposium on Computer Arithmetic (ARITH'05)  
The Residue Logarithmic Number System (RLNS) represents real values as quantized logarithms which, in turn, are represented using the Residue Number System (RNS).  ...  Compared to the conventional Logarithmic Number System (LNS) in which quantized logarithms are represented as binary integers, RLNS offers faster multiplication and division times.  ...  INTRODUCTION This paper considers a number system that is a composite of two unusual number systems: the Residue Number System (RNS) and the Logarithmic Number System (LNS).  ...
