Hi Colin,

 

I was providing you some referances how the SDRAM controller is used with PCIe user application.

 

The xapp859 will give some suggetions.However there is no relation with xapp1052.

 

You have to have a SDRAM controller instantiated in xapp1052 top level and DMA,Userlogic should have datapath to read and write.

 

Regards,

KR

HI,KR

I have download the xapp859,But it is too complexed for me!

If I want to use the xapp1052,do I need to generate a FIFO(user the core generate)?and 

I have another problem,I think there are many difference between the 859 and 1052

For example .the DMA have many difference~!!

And,does Xilinx support the soft SOURCE CODE????I can't find it!!

Thanks in advance~ Sorry for my bad english.
