Research ArticleOpen accessEvery word in the titleHARDWARE REALIZATION OF HIGH SPEED ELLIPTIC CURVE POINT MULTIPLICATION USING PRECOMPUTATION OVER GF(P)N. Shylashree, V. SridharTwo new theoretical approaches for the hardware realization of high speed elliptic curve point multiplication over a prime field (GF(p)) are presented. These hardware implementations use multiple units of elliptic curve point doublers, point adders and multiplexers. The modular hardware approach used here provides high speed and scalability. …Journal of Computer Science, Vol. 10, Issue 7 · 4 Feb 2014 · 6,611 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleDESIGN OF FUZZY LOGIC CONTROLLER FOR ONLINE SPEED REGULATION OF DC MOTOR USING PWM TECHNIQUE BASED ON LABORATORY VIRTUAL INSTRUMENT ENGINEERING WORKBENCHPrema Kannan, Senthil Kumar Natarajan, Subhransu Sekar DashThis study details online speed regulation of DC motor using PWM technique based on LabVIEW. A fuzzy logic controller is designed to change the pulse width of switching signal applied to the converter and thereby the voltage fed to the armature of the separately excited DC motor to regulate the speed. The proposed system is connected to the server computer … …Journal of Computer Science, Vol. 9, Issue 8 · 4 Jul 2013 · 6,715 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVLSI Implementation of FIR Filter Using Computational Sharing Multiplier Based on High Speed Carry Select AdderS. Karunakaran, N. KasthuriRecent advances in mobile computing and multimedia applications demand high-performance and low-power VLSI Digital Signal Processing (DSP) systems. One of the most widely used operations in DSP is Finite-Impulse Response (FIR) filtering. In the existing method FIR filter is designed using array multiplier, which is having higher delay and power dissipation. The proposed method presents a programmable digital Finite Impulse … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 5 Jan 2013 · 7,179 accessesView PDFCite
