Using external memory of ADSP-21065L - "Allia Donna D. Go" - Jun 17 15:30:17 2007



Hi! I'm having a problem with my thesis. I need to know how to use the 
external memory of ADSP-21065L. My thesis is about MP3 Decoder using 
ADSP-21065L with audio enhancements. An MP3 file should come from an 
external memory, i.e. SDRAM, SD card. Now I don't know how to interface 
this to the dsp board.

I would really appreciate any help from you. Thank you!

hi,
2065L does not support SD Card Interface. 
SDRAM will be of not much help as it is a volatile memory.
You can try to use the Flash memory to store the mp3 files. The size of mp3 file will be very
limited, but you should be able to demonstrate the real time mp3 player.
