Ddr2 ram

Question

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.

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!!!
