ADSP-21479 - External RAM based Delay

H at all,

  I've recently purchased an ADSP-21479 EZLite eval board and I'm experimenting some simple algorithms.

My application requires a very long multichannel audio delay (at least 1 second per 8 channel) ad 96Khz.

The required amount of ram for the delay buffers is:  96.000*4byte*8channel = 3.072.000 Bytes

Since the demoboard have a 32MB Micron SDRAM memory installed in it my intention is to use this memory to store delay buffers.


Is there any example of an external memory based delay? Could be fine also a simple external memory talk through example.


Thanks a lot
