Different buffer sizes in audio I/O

Hello all,


I am using the ADSP-21364 EZ-KIT Lite and I have done some simple processing based on the block-based talkthrough example. Now I want to code a simple overlap-add method. As I understand, the overlap-add method reads a buffer equal to the window length (e.g. 1024 samples) and outputs a buffer equal to the hop size/overlap size (e.g. 50% that is 512 samples).


So, I would like to know if it is possible for the ADC to work with a buffer of 1024 samples and the DAC to work with a buffer of 512 samples. I suppose I should setup two different SPORTS for this? Could someone provide an example or some guidance?


Thanks for you help,
