  This not a embeded system but a VLSI project. How much do you know about the topic?
  
  I suppose you have enough knowledge about HDLs and timing analysis.

  In fact this is not the first time I do something connected to VLSI circuits. We've studied VLSI at school and we've done some simple programms on FPGA like adders, counters, multiplexers... But I've never done a project on FPGA. But looking at the datasheet I've downloaded from the xilinx website, I think with efforts I can come up with something nice, using the memory of the board, the DAC and stuff. However I don't know how to make time analysis.
  As for further details concerning the project, I would like to make a system to which I upload an mp3 file, and then he reads it (of course speakers and the rights intrefaces are needed to do that).

  What you basically need is sample the mp3 and generate a PWM wave out of it. So one block of your hardware is a PWM generator. Another will be ADC. Make sure you sample at some optimum level otherwise the quality will be very bad. The generated PWM can be directly fed to speakers.

  Thank you [Prototype]
  I welcome any other suggestion

  Hello everyone
  Here's my idea :
  I decode the mp3 file on fpga -> I stream it out to the DAC -> the DAC's output is fed directly to the speakers
  how about that?

  The voltage op of the DAc has to sufficient and also the power op of it
  
  If power is less then go for a stage of amplifiers

  Thank you Jeffrey Samuel for your advice.
  At this stage I'm still looking for a way to decode the mp3 file.
