11. On Image Compression using Curve Fitting
Master-uppsats, Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikationSammanfattning : Context: Uncompressed Images contain redundancy of image data which can be reduced by image compression in order to store or transmit image data in an economic way. There are many techniques being used for this purpose but the rapid growth in digital media requires more research to make more efficient use of resources. LÄS MER
12. Data Compression for use in the Short Messaging System
Kandidat-uppsats, Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikationSammanfattning : 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).

13. Modelling and implementation of an MPEG-2 video decoder using a GALS design path.
Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknikSammanfattning : 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
14. MP3 Decoder in Theory and Practice
Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandlingSammanfattning : MPEG audio coding under the name MP3 has become one of the most popular standards for digital audio broadcasting and videos. High compression ratios offered by MP3 codecs in various stand alone players and hand held devices over the last few years has increased its popularity immensely. LÄS MER
15. Parallel JPEG Processing with a Hardware Accelerated DSP Processor
Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknikSammanfattning : 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
