—The motivation behind this study is the impact
made on today’s social media by music players, which include
features like portability, size and equalizer functionality for the
best possible sound output quality. The objective of this study
was to develop a system that reads the wave files present on the
Secure Data (SD) card, adjust the equalizer settings
incorporated on it, and play them on the speaker with the best
possible quality sound output. This was done with the help of
the SD card slot provided on the DE2 board, and its
implementation on the board using Altera’s SoPC (System-ona-
Programmable-Chip) Builder in the Altera Quartus 9.1
environment. Nios II is a 32-bit soft-core embedded processor
architecture designed specifically for the Altera family of
FPGAs. Programming of the Nios II processor is done using
the Nios II 9.1 IDE tool. An extension of this work could
include incorporation of video—along with the audio on the
DE2 board since there is a VGA slot included on the board
features and the movement of the wave files on the SD card
with the help of the keys present on the DE2 board.
