Hi Vignesh , It is very easy. The best option is to use EDMA transfers. Maybe in the future you require REAL TIME PROCESSING , EDMA transfer is the unique option.So learn it. There is a very good example about How to Use EDMA transfers: It is an old example that comes with CCS 1.0 ( I think) , I looked in the web and you can find it : http://www.rose-hulman.edu/Class/ee/yoder/ece581/iw6000/labs/bsl/dsk_example s/codec/edma/Dsp/ the code is codec_edma.c If it is your first using EDMA transfers , do not worry . It is easy , you have to learn the PDF files : TMS320C6000 Peripherals Reference Guide Literature Number: SPRU190D See EDMA Controller.
