  1. 36. Design of Single Scalar DSP based H.264/AVC Decoder

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Di Wu Tiejun Hu; [2005]
    Nyckelord :Datorteknik; H.264; Decoder; DSP; Accelerator; HW SW partitioning; Datorteknik;

    Sammanfattning : H.264/AVC is a new video compression standard designed for future broadband network. Compared with former video coding standards such as MPEG-2 and MPEG-4 part 2, it saves up to 40% in bit rate and provides important characteristics such as error resilience, stream switching etc. LÄS MER

  3. 37. A study of CABAC hardware acceleration with configurability in multi-standard media processing

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

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

    Sammanfattning : 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. LÄS MER

  4. 38. Parallel JPEG Processing with a Hardware Accelerated DSP Processor

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Mikael Andersson; Per Karlström; [2004]
    Nyckelord :Datorteknik; JPEG; JFIF; 2-D DCT; Huffman; Accelerator; HW SW partitioning; Datorteknik;

    Sammanfattning : This thesis describes the design of fast JPEG processing accelerators for a DSP processor. Certain computation tasks are moved from the DSP processor to hardware accelerators. The accelerators are slave co processing machines and are controlled via a new instruction set. LÄS MER

  5. 39. Low Bitrate Video and Audio Codecs for Internet Communication

    Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för telekommunikation och signalbehandling

    Författare :Jonas Nilsson; Jesper Nilsson; [2003]
    Nyckelord :video; audio; wavelet; transform; jpeg2000; msc3k;

    Sammanfattning : This master thesis discusses the design and the implementation of an own developed wavelet-based codec for both video and image compression. The codec is specifically designed for low bitrate video with minimum complexity for use in online gaming environments. LÄS MER

  7. 40. 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
