Accessing DDR2 SDRAM without using Nios processor.

Thanks for your reply.

Well, I tink i've already seen it, and i am still trying to work out with the frame reader. I'll take another

but i need to take the video pakets over the avalon-st interface and save them for an entire field as image into the SDRAM. then, read that image with a custom block, not with the frame reader, then save the processed image into a new memory (maybe SSRAM this time) and then read the processed image with the frame reader.

My problem is how can i access the SDRAM to write and then how can i read from that writing a custom block? wich are the signals I need to interface with the SDRAM DDR2 hp controller provided by Altera?

Anyway, if there are more simple way to make something like that, i would choose the simple way!

Thanks a lot for the reply

best regards

Phate.
