Abstract-This project deals with the NIOS II system, which reads wave files from an SD card in real time and produces sound output through speakers while providing user interaction such as pause music, fast forward and rewind. The Altera DE2 board supports communication through the SD card. It also features sound recording for 10 seconds by giving a microphone to the LINE-IN provided on the DE2 board and speakers to the LINE-OUT. These features are realized using Altera SOPC builder in the Altera Quartus 9.1 environment. The overall goal of this project is to explore various applications that are possible with Altera's DE2 Board.Index Terms-DE2 board, NIOS II processor, SOPC builder, SD card, LCD, Cyclone II 2C35 FPGA.
