Sammanfattning
This thesis has the intention to create a base for renewal of the DAT095 (Electronic System Design Project) course. As a basis for the new project, implementation of a LEON3 processor on a FPGA board was done and a MP3 player application was run on it. The MPG123 [15] application's source code was used and modified according to the system and by using hardware/software co-design techniques a complete system was designed. The audio interface hardware core was designed according to the requirements of the digital to analog converter MCP4288 [3]. Necessary interfaces were implemented according to the AMBA bus. A demonstrator was built on the Digilent Spartan3 xc3s1000 board [4]. During the analysis of the MP3 decoder, it was seen that the Inverse Discrete Cosine Transform (IDCT) part of the decoder algorithm was too computation-intensive and a hardware implementation for that part was made and attached to the processor‟s AMBA bus as a slave. The MP3 decoder software and the IDCT hardware were working together to decode the data. Finally the development platform was changed to Digilent Atlys Spartan6 FPGA development board [21] that gave a more flexible usage for future works. The LEON3 processors template design was modified according to the needs of the new development platform and the MPG123 application was run on it.
