AT89C51SND1 based mp3 player

Hello.. I am a student in Timisoara and I've jest started working on a personal project. As the name of the thread sees it is an mp3 player based on the atmel uC and a TLV320DAC23. I am currently designing the prototype board(s).
If there is anyone that has experience with these parts and can help please say so.
For now I would appreciate any links to other similar projects (they are very rare) or any material on similar projects you might have and that you can share.
I'll keep you informed on how things work out.

Thank you
