The Denormal Logarithmic Number System
, 2013
"... Abstract—Economical hardware often uses a FiXedpoint Number System (FXNS), whose constant absolute precision is acceptable for many signalprocessing algorithms. The almostconstant relative precision of the more expensive FloatingPoint (FP) number system simplifies design, for example, by eliminat ..."

, by eliminating worries about FXNS overflow because the range of FP is much larger than FXNS for the same wordsize; however, primitive FP introduces another problem: underflow. The conventional Signed Logarithmic Number System (SLNS) offers similar range and precision as FP with much better performance (in terms
GeometricMean Interpolation for Logarithmic Number Systems

A Serial Logarithmic Number System ALU
"... Serial arithmetic uses less hardware than parallel arithmetic. Serial floating point (FP) is slower than parallel FP. The Logarithmic Number System (LNS) simplifies operations, but a fast serial implementation of LNS has never been proposed previously. This paper presents a fast bitserial LNS that c ..."

Bipartite Implementation of the Residue Logarithmic Number System
"... The Logarithmic Number System (LNS) has area and power advantages over fixedpoint and floatingpoint number systems in some applications that tolerate moderate precision. LNS multiplication/division require only addition/subtraction of logarithms. Normally, LNS is implemented with ripplecarry bina ..."

Digital Filtering Using the Multidimensional Logarithmic Number System
"... We introduce the use of multidimensional logarithmic number system (MDLNS) as a generalization of the classical 1D logarithmic number system (LNS) and analyze its use in DSP applications. The major drawback of the LNS is the requirement to use very large ROM arrays in implementing the additions and ..."

Algorithms for Quantum Computation: Discrete Logarithms and Factoring
, 1994
"... A computer is generally considered to be a universal computational device; i.e., it is believed able to simulate any physical computational device with a increase in computation time of at most a polynomial factor. It is not clear whether this is still true when quantum mechanics is taken into consi ..."

An algorithm and data structure are presented for searching a file containing N records, each described by k real valued keys, for the m closest matches or nearest neighbors to a given query record. The computation required to organize the file is proportional to kNlogN. The expected number of recor ..."
