DMA on DSP

Hello everyone,

I am using VISION SDK 2.11. I want access DMA for following code

for(i =0 ;i < 450;i++)

{

for(j =0; j<1800;j++)

{

 dest[i*1800*3+j] = src[i*1800*3+j]*arr[j];

}

}


I want to access memory through DMA like src memory and dest memory.

How to access Source address through DMA as well as how to process on it , after processing how to store on Destination through DMA.

Please guide me for accessing DMA and provide the solution for same.

Best Regards,

Poonam
