Acceleration of Data Compression Algorithms on Sony PS3 Platform
Breitenbacher, Dominik ; Jaroš, Jiří (referee) ; Šimek, Václav (advisor)
This paper presents the use of PlayStation 3 device for accelerating compression algorithms and tries to show the potencial of PlayStation 3 for use on these tasks. For a demonstration was selected compression method based on the Burrows-Wheeler transformation. The output of the transformation is further transformed by using the Move-To-Front transformation and subsequently encoded by the static Huffman encoding. The compression algorithm has been called PS3BWT. It performs compression by using each of tasks and tries to always use the maximum number of avaible processor units, so the compression is carried out as quickly as possible.

Medical Image Data Compression
Balarin, Jakub ; Španěl, Michal (referee) ; Kršek, Přemysl (advisor)
The efficiency of various compress algorithms on medical images is explored in this paper. It try's to find algorithm or group of algorithms with the best compress efficiency. Except classic algorithms the medicine data properties (it contains many similar image points) can be used to reach higher compress level. We verify delta coding efficienty to final compress ratio. At the end the best founded method is presented.

Acceleration of Burrows-Wheeler Transform Using GPU
Zahradníček, Tomáš ; Drábek, Vladimír (referee) ; Šimek, Václav (advisor)
This thesis deals with Burrows-Wheeler transform (BWT) and possibilities of acceleration of this transform on graphics processing unit (GPU). Methods of compression based on BWT are introduced, as well as software libraries CUDA and OpenCL for writing programs for GPU. Parallel variants of BWT are implemented, as well as following steps necessary for compression, using CUDA library. Amount of compression of used approaches are tested and parallel versions are compared to their sequential counterparts.
