This thesis is dedicated to the principles of a MP3 audio format decoding on available develpoment kits powered by ARM processors. It compares kit MCB2300 with LPC2378 microcontroller and kit Raspberry Pi with Debian operation system. The comparsion is focused on their suitability for MP3 decoder implementation. A complete design of support hardware modules, which complement the missing hardware of development kits is described in detail. Thesis includes the realization of an implementation of a MP3 decoder with additional visual effects in a form of an attached RGB LED strip developed on a Raspberry Pi development kit.

This work deals with the design and implementation of a hardware unit that is capable of playing MPEG-1 Layer III files, compliant with ISO/IEC 11172-3. There are given the benefits of using the MP3 format and principles that make it possible to compress the size of the resulting music recordings. The file format and all parts of the header are thoroughly studied as well as the method of encoding information. The process of the data decoding is divided into several consecutive, more or less discrete functional units and these units are designed and described in a hardware description language VHDL. There are also discussed features of FPGA chips - programmable gate arrays. Those are used for physical realization of the MP3 player. A development board is selected, including such an FPGA chip and other resources that allow synthesis of the entire circuit and playback in real time.
