DDR3 RAM access from PRU program

Is it possible for the PRU program to use DDR3 RAM? I’m looking for a way to interface high resolution camera with the BBB. The PRU in beagle bone looks nice for this job with its good performance. But I wonder if you could use the large 512MB DDR3 RAM with the PRU.

No, because Linux is probably going to need at minimum 50MB to run, and ideally 128-256M for caching, and process housekeeping etc. But you can use a good portion of that DDR memory.

thank you so much! I’m happy to hear that.
Then is there any example using PRU with DDR3 RAM? It’d be very helpful if one could give me a link. I tried googling many times but didn’t find some example yet.
