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 :)

I mean to say, I have already used RAM 2 times. data will be keep on flowing through that designated I/O of the RAM in real time. 

I was afraid how the same I/O of the RAM can be address multiple times in real time vip design!!!
