SRC in ADSP-21489

Hello,

 

I want to use Sample Rate Converter (SRC) from SHARC-21489, I got through the following hardware reference:

http://www.analog.com/media/en/dsp-documentation/processor-manuals/ADSP-214xx_hwr_rev1.1.pdf

 

But I am not able to understand how to use,

Basically this is the flow I am thinking:

1. Read 48 KHz data from file 480 samples.

2. Convert this to 32 KHz.

3. Dump the output to output file.

 

Queries:

Whether the SRC module will work for 16 bit PCM data ? , How to initialize the buffers and how to use the SPORT (as mentioned in the Hardware reference manual)

 

Please help me I am new to this SRU programming, I found a couple of examples where they are taking data from audio jack and the project in Viusal DSP++ , I need in CCES.

 

Regards

Sravan
