SOLID-STATE MP3 PLAYER

The topic for the Final Year Research Project (FYP) is "Solid-State MP3 Player". A
solid-state memory is introduced here to replace the existing compact disc that is used
to store data. The project requires a microcontroller-based interface circuit to control
the player.
A simple block diagram of a complete player basically consists of
• A solid-state memory to store data.
• Initialize the storage into the mode oftransferring the files.
• The microcontroller that control the data transfer between storage and
microcontroller.
i. Data transfer to storage,
ii. Data transfer from storage.
• A decoder to run a decompression algorithm that undoes the compression of
the MP3 file and then a digital-to-analog converter turns the bytes back into
waves.
• An amplifier to boost the strength of the signal and sends it to the audio port,
where a pair of speakers is connected.
The project mainly covers the manipulation of programming language to implement
the routines in the microcontroller.
