GPD2846 MP3 Module: The heart of this mp3 player project is the GPD2846 MP3 Player Audio Decoder module. This module has a SD card slot in which we can insert an SD card with MP3 songs, and when we power the module it will start playing those songs. The module has four holes namely Battery Positive, Ground, Speaker positive and Speaker negative.

A block diagram of the MPEG1 audio system is shown in Fig. 3. Since SSP1605 is a general purpose DSP, several interface units are required to implement specific DSP application such as MPEG1 audio. Required interface units, which are designed in a FPGA of 2K gate, are MIU (Memory Interface Unit), CIU (Codec Inter-face Unit) and HIU (Host Interface Unit).
