  1. 11. Digital Filter Design Using Semidefinite Programming

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Moa Samuelsson; Jimmy Johansson; Fabian Samuelsson; [2015-02-11]
    Keywords : ;

    Abstract : Abstract This thesis explores an optimization based approach to the design problem of digital filters. We show how a digital filter in the form of a discrete linear time-invariant causal system can be characterized by a non-negative trigonometric polynomial, which in turn can be represented by a positive semidefinite matrix known as Gram matrix representation.

  4. 13. High Level Synthesis of FPGA-Based Digital Filters

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Gerald Baguma; [2014]
    Keywords : ;

    Abstract : This thesis work is aimed at the high level synthesis of FPGA based IIR digital filters using Vivado HLS produced by Xilinx and HDL coder produced by MathWorks. The Higher Layer Model of the filter was designed in Vivado HLS, MATLAB and Simulink. Simulations, verification and Synthesis of the RTL code was done for both tools. READ MORE

  5. 14. Visual Quality Improvement of Digital Video by Stabilization Using Adaptive CMAC Filtering

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Amir Zahoor; Wittaya Koodtalang; [2013]
    Keywords : Digital video stabilization; DVS; Cerebellar model articulation controller; CMAC; Smoothness index; Peak signal to noise ratio; Point spread function;

    Abstract : A Digital Video Stabilization (DVS) system removes the unwanted shaking in the videos acquired by hand-held cameras and preserves the panning. In this thesis work, a digital video stabilization model is proposed based upon adaptive cerebellar model articulation controller (CMAC) filtering. READ MORE

  6. 15. Optimising IIR Filters Using ARM NEON

    University essay from Malmö högskola/Fakulteten för teknik och samhälle (TS)

    Author : Sebastian Bentmar Holgersson; [2012]
    Keywords : ARM; NEON; SIMD; IIR; biquad;

    Abstract : ARMs processorserie Cortex-A9 har stöd för SIMD-instruktioner med hjälp av NEON MPE. Detta innebär att processorn kan använda sig av vektor-instruktioner som kan utföra operationer på ett flertal element med varje instruktion. READ MORE
