Picozed SDR : how to minimized non-DDS access to RAM

Hi,

     Setup: PicoZed SDR, FMC carrier card,  HDL_2015_R2, pre-built SDcard images

 

   I am conducting an experiment to measure how much DDR3 bandwidth is left after AD9361  reads and  writes its samples from DDR3.  Therefore I would like to turn off all non-DDS samples related access to DDR3 (eg video frame buffer).  Linux assess is fine.  May I know which is the best way to do so that AD9361 still continues to rd/wr to DDR3?

 

Regards,
