MP3 storage and playback:
1) First after inserting memory stick/card in the card slot the MP3 data is decoded and the file information is sent by the processor to
the FPGA where it is stored in the 64MB SDRAM along with OSD
2) While during playback when we select any MP3 file then the data is processed by the processor and the I2S data is sent to the
audio DAC IC where it is converted into analog AV_L and AV_R signals.
3) These analog audio signals are then sent into the jack board for further processing.
