The Interval Logarithmic Number System
This paper introduces the Interval Logarithmic Number System (ILNS), in which the Logarithmic Number System (LNS) is used as the underlying number system for interval arithmetic. The basic operations in ILNS are introduced and an efficient method for performing ILNS addition and subtraction is presented. The paper compares ILNS to Interval Floating Point (IFP) for a few sample applications. For...
متن کاملAddition/Subtraction of Logarithmic Number System
This paper tells the technique for low power addition/subtraction of Logarithmic number system (LNS). Firstly, the impact of partitioning the look up tables (LUT) required for addition/subtraction on complexity, performance is studied. Two design parameters namely organisation of word and base are also taken into consideration. For addition and subtraction of LNS, MATLAB is also used to calcula...
متن کاملSemi-Logarithmic Number Systems
We present a new class of number systems, called Semi-Logarithmic Number Systems, that constitute a family of various compromises between floating-point and logarithmic number systems. We propose arithmetic algorithms for the Semi-Logarithmic Number Systems, and we compare these number systems to the classical floating-point or logarithmic number systems. performed using tables for the function...
متن کاملA GPU Implementation of the Complex Logarithmic Number System
In this paper we present a technique to implement the Complex Logarithmic Number System (CLNS) on a Graphics Processing Unit (GPU). Although CLNS multiplication is a simple FP addition, CLNS addition involves evaluations of transcendental functions, which can be carried out in a few different ways by utilizing the GPU hardware resources, such as the special function units, the floating point un...
متن کاملApplying the Logarithmic Number System to Application-Specific Designs
When designing a microprocessor, the choice of a given arithmetic greatly impacts characteristics such as the implementation of the functional units, the required word size, and even the optimum algorithms that can be used. The diversity of products that incorporate a microprocessor makes the best choice application or system dependent. The Logarithmic Number System (LNS) allows very fast, powe...
