  1. 1. CAL code generator for Epiphany architecture

    Master-uppsats, Högskolan i Halmstad/Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Yang Mingkun; [2013]
    Nyckelord :;

    Sammanfattning : Various approaches have been proposed to address high performanceparallel computing, among which, data flow paradigm is one particular promis-ing candidate. This thesis work builds a code generator for CAL, one oflanguages supporting data flow paradigm, targeting many-core architecture,namely Epiphany, which is one parallel architecture, and promises to scalethe number of processors horizontally.

  3. 2. Parallel Computing based on GPGPU using Compute Unifed Device Architecture

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Lifeng Xu; [2011]
    Nyckelord :;

    Sammanfattning : The demand of processing a huge amount of data within a limited time and the developing of computing capability of Graphic Process Unit (GPU) lead us to the world of parallel computing on General Purpose GPU (GPGPU). Because of the exposed parallelism, GPGPU could assign processing tasks to multiple threads and execute these threads simultaneously. LÄS MER

  4. 3. Modelling and implementation of an MPEG-2 video decoder using a GALS design path.

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Kaj Rosengren; [2006]
    Nyckelord :GALS; Simulink; MPEG; IDCT; Huffman;

    Sammanfattning : As integrated circuits get smaller, faster and can fit more functionality, more problems arise with wire delays and cross-talk. Especially when using global clock signals distributed over a large chip area. This thesis will briefly discuss a solution to this problem using the Globally Asynchronous Locally Synchronous (GALS) design path. LÄS MER

  5. 4. Implementering av 1D-DCT

    Magister-uppsats, Institutionen för systemteknik

    Författare :Edmin Zilic; [2006]
    Nyckelord :IDCT; DCT; MPEG; JPEG; multiple constant multiplication; subexpression sharing.;

    Sammanfattning : IDCT (Inverse Discrete Cosine Transform) is a common algorithm being used with image and sound decompression. The algorithm is a Fourier related transform which can occur in many different types like, one-dimensional, two-dimensional, three-dimensional and many more. LÄS MER

  7. 5. Inverse Discrete Cosine Transform by Bit Parallel Implementation and Power Comparision

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Divya Anshu Bhardwaj; [2003]
    Nyckelord :Electronics; Bit Serial; Bit Paralell; DCT; IDCT; JPEG; MPEG; ASIC; Compression; Decompression; Components; Elektronik;

    Sammanfattning : The goal of this project was to implement and compare Invere Discrete Cosine Transform using three methods i.e. by bit parallel, digit serial and bit serial. This application describes a one dimensional Discrete Cosine Transform by bit prallel method and has been implemented by 0. LÄS MER
