    • A comparative analysis between logarithmic number system and floating-point ALU 

      Rizalafande, Che Ismail, Dr.; Coleman, John Nicholas; Norzahiyah, Nordin; Zaliman, Sauli, Dr. (AENSI Publisher All rights reserved, 2013-10)
      The ease and accuracy of executing the multiplication and division operations by using either fixed-point addition or subtraction is what makes the logarithmic number system an attractive option. However, its main drawback ...

    • Development of varied CMOS ring oscillator topologies in 0.13-μm CMOS technology 

      Sohiful Anuar, Zainol Murad, Dr.; Rizalafande, Che Ismail, Dr.; Mukhzeer, Mohamad Shahimin, Dr.; Mohd Fairus, Ahmad; Rohana, Sapawi (Trans Tech Publications Inc., 2014)
      This paper presents varied CMOS ring oscillator topologies using Silterra 0.13-µm Process. Three topologies of ring oscillators have been designed which is the single-ended ring oscillator, differential ring oscillator and ...

    • High performance video graphic architecture using hybrid logarithmic system 

      Rizalafande, Che Ismail, Dr.; Sohiful Anuar, Zainol Murad, Dr.; Mohd Nazrin, Md Isa, Dr.; Asral Bahari, Jambek, Dr.; Phak Len, Eh Kan, Dr.; Fazrul Faiz, Zakaria; Mohd Fikri Che Husin (Universiti Malaysia Perlis (UniMAP)School of Microelectronic Engineering, 2014-05)
      It is known that the engines generate an image from a scene described as a list of vertices, a list of triangles and the position of the camera. The transformation stage transforms the vertices from the scene coordinates ...

    • A high speed and well-structured partial product generator for parallel multiplier 

      Rizalafande, Che Ismail; Beckett, P (Univerisiti Malaysia Perils, 2007)
      Previously reported multiplication algorithms mainly focus on rapidly reducing the partial product rows down to final sums and carries used for the final accumulation. In this paper, an efficient approach for partial product ...

    • Improved addition and subtraction in logarithmic number system: Technique and analysis 

      Rizalafande, Che Ismail, Dr.; Norzahiyah, Nordin; Asral, Bahari Jambek, Dr. (AENSI Publisher All rights reserved, 2013-10)
      Logarithmic Number System (LNS) is an alternative beside Floating Point (FLP) when an application requires a large dynamic range in the number processed. It allows simple implementation of multiplication and division using ...

    • Improved subtraction function for logarithmic number system 

      Rizalafande, Che Ismail, Dr.; Sohiful Anuar, Zainol Murad, Dr.; Hussin, R. (Malaysian Technical Universities Network (MTUN), 2012-11-20)
      Logarithmic number system can be highly considered as an alternative to floating-point, specifically for applications that require a wide dynamic range of numbers for their arithmetic operations. To date, its implementation ...

    • Improved subtraction function for logarithmic number system 

      Rizalafande, Che Ismail, Dr.; Sohiful Anuar, Zainol Murad, Dr.; Razaidi, Hussin; Coleman, John Nicholas (Elsevier Ltd., 2013)
      Logarithmic number system can be highly considered as an alternative to floating-point, specifically for applications that require a wide dynamic range of numbers for their arithmetic operations. To date, its implementation ...

    • Robotic hand for physiotherapy 

      Muhammad Firdaus, Mohd Radzi; Tengku Muhammad Aiman, Tengku Mohd Yusof; Rizalafande, Che Ismail, Dr. (Supervisor); Mohd Fikri, Che Husin (Supervisor) (Macao Innnovation & Invention Association, 2013-06-28)
      The main goal of this project is to find new alternatives to help patients who have been recovered from stroke to move their hands. This product will help patients accurately grasping or whole move their fingers. Indirectly, ...
