FPGA implementation of Logarithmic Unit
Introduction Implementation of floating point in FPGA (Field Programmable Gate Arrays) is not easy. Paper presents FPGA core implementing these operations by representation of floating point numbers as 32-bit integer (fixed point) logarithm [1]. Basic arithmetical operations are performed in the logarithm numbering system (LNS) suitable for FPGA. Implemented intellectual property core takes jus...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولSemi-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 کاملParallel FPGA Implementation of RSA with Residue Number Systems
In this paper, we present a new parallel architecture to avoid side-channel analyses such as: timing attack, simple/differential power analysis, fault induction attack and simple/differential electromagnetic analysis. We use a Montgomery Multiplication based on Residue Number Systems. Thanks to RNS, we develop a design able to perform an RSA signature in parallel on a set of identical and indep...
متن کاملImplementation of Floating Point and Logarithmic Number System Arithmetic Unit and Their Comparison for Fpga
Floating point (FP) representation is commonly used to represent real numbers. Some papers have suggested the use of logarithmic number system (LNS) in addition to floating point. In LNS, a real number is represented as a fixed point logarithm. Therefore multiplication and division in LNS are much simpler in comparison to that in FP, so the LNS can be beneficial if addition and subtraction can ...
