  1. 16. Design and implementation of a decimation filter using a multi-precision multiply and accumulate unit for an audio range delta sigma analog to digital converter

    University essay from Institutionen för systemteknik

    Author : Erik Lindahl; [2008]
    Keywords : decimation; digital filter; FIR; hardware implementation; multi precision; delta sigma;

    Abstract : This work presents the design and implementation of a decimation filter for a three bits sigma delta analog to digital converter. The input is audio with a oversampling ratio of 32. Filter optimization and tradeoffs concerning the design is described. The filter is a multistage filter consisting of two cascaded FIR filters. READ MORE

  3. 17. To Calculate with Averages : What is a Good Result in the Absence of the Correct?

    University essay from Institutionen för informationsteknologi

    Author : Niklas Molin; [2008]
    Keywords : ;

    Abstract : This thesis specifies the foundation for a computer system that operates on averages of measured values provided by automatic measurements systems. This consists of specifying a data object for the average of measured values and fusion methods for that object. READ MORE

  4. 18. Computations in Prime Fields using Gaussian Integers

    University essay from Institutionen för systemteknik

    Author : Adam Engström; [2006]
    Keywords : gaussian integers; prime fields; arithmetic; logic minimization;

    Abstract : In this thesis it is investigated if representing a field Zp, p = 1 (mod 4) prime, by another field Z[i]/ < a + bi > over the gaussian integers, with p = a2 + b2, results in arithmetic architectures using a smaller number of logic gates. Only bit parallell architectures are considered and the programs Espresso and SIS are used for boolean minimization of the architectures. READ MORE

  5. 19. A study of CABAC hardware acceleration with configurability in multi-standard media processing

    University essay from Institutionen för systemteknik

    Author : Oskar Flordal; [2005]
    Keywords : CABAC; Arithmetic coding; H.264; JPEG 2000; instruction level optimizing; accelerators; assembler; VLC; encoder; hardware reuse; profiling; DSP; multimedia;

    Abstract : To achieve greater compression ratios new video and image CODECs like H.264 and JPEG 2000 take advantage of Context adaptive binary arithmetic coding. As it contains computationally heavy algorithms, fast implementations have to be made when they are performed on large amount of data such as compressing high resolution formats like HDTV. READ MORE

  6. 20. A direct comparison between mathematical operations in mental arithmetic with regard to working memory’s subsystems

    University essay from Institutionen för datavetenskap

    Author : Felix-Sebastian Koch; [2004]
    Keywords : Interdisciplinary studies; mental arithmetic; dual-task methodology; Baddeley’s working memory model; number pairs; TVÄRVETENSKAP;

    Abstract : This study examined the idea that each mathematical operation (addition, subtraction, multiplication and division) is mainly linked to one of the components of working memory as proposed by Baddeley. The phonological loop, visual-spatial sketchpad and central executive have been studied using a dual-task methodology with 7 different secondary tasks. READ MORE
