  1. 1. 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

  3. 2. Data Compression for use in the Short Messaging System

    University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Author : Måns Andersson; [2010]
    Keywords : compression; sms; arithmetic; lambda; huffman; lzw; lz77; lz78; Fristående kurs;

    Abstract : Data compression is a vast subject with a lot of different algorithms. All algorithms are not good at every task and this thesis takes a closer look on compression of small files in the range of 100-300 bytes having in mind that the compressed output are to be sent over the Short Messaging System (SMS).

  4. 3. Encryption in Delocalized Access Systems

    University essay from Institutionen för teknik och naturvetenskap

    Author : Henrik Ahlström; Karl-Johan Skoglund; [2008]
    Keywords : Access systems; Cryptography; Public Key; Embedded system; Large integer arithmetic.;

    Abstract : The recent increase in performance of embedded processors has enabled the use of computationally heavy asymmetric cryptography in small and power efficient embedded systems. The goal of this thesis is to analyze whether it is possible to use this type of cryptography to enhance the security in access systems. READ MORE

  5. 4. Hardware / Software co-design for JPEG2000

    University essay from Institutionen för systemteknik

    Author : Per Nilsson; [2006]
    Keywords : JPEG2000; Discrete Wavelet Transform; arithmetic coding; DSP processors; HW SW partitioning; ;

    Abstract : For demanding applications, for example image or video processing, there may be computations that aren’t very suitable for digital signal processors. While a DSP processor is appropriate for some tasks, the instruction set could be extended in order to achieve higher performance for the tasks that such a processor normally isn’t actually design for.

  6. 5. 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
