Instanciate multiple DDR2 controllers ?

Hi,

I update my own previous post because I always search documentations / code examples / projects about multi port controller.

Actually, in a first time, I try to evaluate the Microtronix IP (link provided above) but in terms of price, I can't use this for my project... not enough money.

So I need to develop my own multi port controller logic. I would like tu use altera DDR2 HP IP and build my own logic around.

Please, I need more informations or examples, especially on how making a good multiplexing of all my ports, how giving priority at each port ...

Even a documentation will be welcome!

Thanks for all.

Bye.
