Introduction of Mp3 decoder using altera de 2 board



                                                            ALTERA DE 2 BOARD

Digital design using a Field Programmable Gate Array (FPGA) device is a rapidly evolving field. A complete embedded system can be built and programmed into a single FPGA chip for digital signal processing applications. The increasing density and capacity of these devices make it possible to implement an entire embedded system on a single chip. The goal of the project is to design an MPEG Layer III (MP3) player using a “Altera” FPGA board. The system will read an MP3 file from a compact flash memory, decode the MP3 bit stream into 16-bit pulse code modulated (PCM) outputs using a standard MP3 decoding algorithm, and play the output through an external speaker. Hardware description language such as Verilog HDL is used to drive external peripherals, including the stereo Audio codec. The Audio codec converts the digital PCM outputs into an analog sound wave. The software and hardware designs are integrated on the Embedded Development Kit platform. In this project, data compression techniques are used in MP3 encoding and decoding are explored and tested on hardware.
