Design guidelines for implementing external memory interfaces in Stratix II and Stratix II GX devices

Posted: 05 Mar 2007 ?? ?Print Version ?Bookmark and Share

Keywords:Stratix II? DDR memory? DDR2? SDRAM? memory interface?

Stratix II offers support for double data rate memories, such as DDR2/DDR SDRAM, QDRII+/QDRII SRAM, and RLDRAM II interfaces. Applications with these memory interfaces include PCs, embedded processing, image processing, storage, communications, and networking. Designing applications with memory interfaces can be challenging considering the different requirements that the memory standards impose on the controller. Moreover, changing a portion of the interface can affect many other things in the application such that designers have to pay close attention to each step of the design process. Knowing the proper design flow is crucial in reducing design and debug time to get the application up and running.
