Design of MP3 Player Application with Nios II Embedded Evaluation Kit, Cyclone III Edition

摘要

A MPEG-1 Audio Layer 3, commonly referred as MP3, is a patented digital audio encoding format using a form of lossy data compression . A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by the customer or designer. We are aiming at implementing a MP3 Player application with the FPGA based Nios II Embedded Evaluation Kit, Cyclone III Edition. Implementation of MP3 Player can be done by first instantiating a Nios II system in the board. Nios II system can be build around the altera’s Nios II processor using the SOPC builder tool of the quartus II CAD tool. The SOPC builder tool generates the VHDL code of the defined system. Thus we get two files .SOF & .ELF from them we get flash files. Upload of these files on SD Card of kit initiates the application.This upload can be done in two ways ,ud 1.In system SD Card update,ud 2.Remote system update.ud Thus the application is uploaded and mp3 files can be played on the kit. Specified controls like skip, pause, play, volume ,balance are also has to be implemented
