FPGA BASED MP3 DECODER
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 2
Abstract
The goal this project is to design an MPEG Layer III (MP3) player using a Xilinx Virtex 5 FPGA board. Hardware description language such as VHDL is used through drive external peripherals, including the stereo AC97 codec and LCD controller. The increasing density and capacity of these devices make it possible to implement an entire embedded system on a single chip. The system will read an MP3 from a compact flash memory, decode the MP3 bit stream to 16 bit pulse code modulated (PCM) outputs using a standard MP3 decoding algorithm, and play the output into an external speaker. The software and hardware designs are integrated on the Xilinx Embedded Development Kit platform. In this project, data compression techniques are used in MP3 encoding and decoding are explored and tested on hardware. Digital design using a Field Programmable Gate Array (FPGA) devices is a rapidly evolving field. The AC97codec converts the digital PCM outputs through an analog sound wave, and the LCD controller displays the title and author information of the selected song. C programming language is used towards run on a Micro blaze 32 bit processor.
