  1. 11. Low Cost Floating-Point Extensions to a Fixed-Point SIMD Datapath

    University essay from Datorteknik; Tekniska högskolan

    Author : Gaspar Kolumban; [2013]
    Keywords : ePUMA; floating-point; SIMD; VPE; fixed-point datapath; IEEE 754;

    Abstract : The ePUMA architecture is a novel master-multi-SIMD DSP platform aimed at low-power computing, like for embedded or hand-held devices for example. It is both a configurable and scalable platform, designed for multimedia and communications. READ MORE

  3. 12. Anonymous Authentication Using Secure Multi-Party Computations

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Maqsood Ahmad; [2011]
    Keywords : ;

    Abstract : Typical authentication systems provide a method to allow registered users access to protected resources after the user successfully authenticates. A user successfully authenticates by proving his or her valid identity if he or she is a registered user. READ MORE

  4. 13. Modeling, Control and Automatic Code Generation for a Two-Wheeled Self-Balancing Vehicle Using Modelica

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Carlos Javier Pedreira Carabel; Andrés Alejandro Zambrano García; [2011]
    Keywords : Technology and Engineering;

    Abstract : The main goal of this project was to use the Modelica features on embedded systems, real-time systems and basic mechanical modeling for the control of a two-wheeled self-balancing personal vehicle. The Elektor Wheelie, a Segway-like vehicle, was selected as the process to control. READ MORE

  5. 14. Analysis of Fix‐point Aspects for Wireless Infrastructure Systems

    University essay from Karlstads universitet/Fakulteten för teknik- och naturvetenskap

    Author : Andreas Grill; Robin Englund; [2009]
    Keywords : fixed-point; fixed point; telecommunication; DSP; MATLAB; Fixed‐Point Toolbox; least squares solution; floating point; Householder QR decomposition; saturation; quantization error;

    Abstract : A large amount of today’s telecommunication consists of mobile and short distance wireless applications, where the effect of the channel is unknown and changing over time, and thus needs to be described statistically. Therefore the received signal can not be accurately predicted and has to be estimated. READ MORE

  6. 15. MIMO Multiplierless FIR System

    University essay from Institutionen för systemteknik

    Author : Muhammad Imran; Khursheed Khursheed; [2009]
    Keywords : MIMO Multiplierless FIR system; Generalised MCM Algorithm; Multiplierless Multiplication;

    Abstract : The main issue in this thesis is to minimize the number of operations and the energy consumption per operation for the computation (arithmetic operation) part of DSP circuits, such as Finite Impulse Response Filters (FIR), Discrete Cosine Transform (DCT), and Discrete Fourier Transform (DFT) etc. More specific, the focus is on the elimination of most frequent common sub-expression (CSE) in binary, Canonic Sign Digit (CSD), Twos Complement or Sign Digit representation of the coefficients of non-recursive multiple input multiple output (MIMO)  FIR system , which can be realized using shift-and-add based operations only.
