Hi guys,
Im implementing noise cancelling in DSK6711 using PCM3003.
Could anyone tell me if there is any way i can store or save my filtered audio speech directly
from CCS and not from the PCM3003 output.
Thanks

There are a couple of ways:

1) Use file I/O functions, which will transfer data via CCS + JTAG.  This method is slow, and
should only be used in
main(), before (or after) real-time code is running.

2) There are free software packages / DLLs out there that will transfer data through the
C6711's HPI interface via the
PC parallel port connection.  This method is suitable for real-time communication.

Here are a couple:

I think I've seen others when Googling before, but not sure.  Try combining DSK 6711
with keywords like DLL, parallel port, 'real-time data transfer', etc.
