Writting data in DDR3 memory using my ip core

Hi,

 

I want to save some data generated in my ip core to the DDR3 memory of the Zynq-7000 EPP. I have to write the data in random (determined by some calculus) positions of the DDR3 memory. I have taken a look to the different options related with the use of the different kinds of DMA provided by Xilinx,but it doesn't work.
I have found the solution to write data generated by my ip core, but i have not found any solution to write this data in the address generated by my ip core.

 

Can anybody recommend me some possibilities?

 

Thank you.

Re: Writting data in DDR3 memory using my ip core

Hi,

 

What are the random addresses generated?

Do  they fall under DDR3 address range? What is your difficulty in wrting to DDR3 memory?

Assuming you are uisng AXI PS DDR, you need to maintain AXI addressing rules, have you  done that and facing issues?

 

Regards,

Vanitha
