Ddr2 ram

[Altera_Forum]

Hi 

 I am working on cyclone II and quartus II v6.0. I want to use DDR2 RAM for multiple time in my image processing design to buffer frame. I want to ask is there any restriction or limitation about using the RAM ?

Hi Socrates! 

 I am using ram at 130MHz.   Actually I want to ask is there any limitation regarding I/O of RAM, if we use it 5 or 6 times in our design? I have already use ram 2 times to buffer frames.(deinterlacer and tripple buffer before vga) I have use 32bit avalon address bus and 64bit data bus while using ram.

What do You mean use 5 or 6 times? Use I/O as much as You want :)
