how i can load or store data in DDR SDRAM in spartan3E kit board ?

dear all
I have spartan 3E development kit (starter kit) include DDR SDRAM and i want to load data or store data(more than 50Mbit) on it and the read it by FPGA for some processing
- i want to know how the data stored in RAM ?
- how can i read from RAM?

wait your help

regards
 

Check Xilinx web site and you find lots of app notes and tutorial on how to use the DDR controller. If you have access to EDK, then things will be much easier. Otherwise you have to make some tricks to get things to work properly.
This is from the DDR access on Spartan 3E 500 Starter Kit | Comp.Arch.FPGA | FPGARelated.com
Although it is for DDR2 on a different board, you might be interested
in an example we created at Avnet to modify the MIG testbench to
simplify it and add comments. You can find it at www.em.avnet.com/spartan3a-dsp
--> Support Files & Downloads --> S3A1800DSP DDR2 MIG Simplified
Verilog User Logic. I think the similarities between DDR2 and DDR
make it useful.

Did you read any of the messages on the link? Did you try any of the code there? If you try, you can find your answer there.
