【应用笔记】Stratix II、Stratix II GX和Arria GX器件外部存储器接口设计指南(External Memory Interface Design Guidelines for Stratix II,Stratix II GX, and Arria GX Devices)
Stratix? II和Stratix II GX器件对DDR存储器(如DDR2/DDR SDRAM、QDRII+/QDRII SRAM和RLDRAM II接口)提供支持，而Arria GX器件支持DDR2和DDR SDRAM接口。
Stratix? II and Stratix II GX devices offer support for double data rate
(DDR) memories, such as DDR2/DDR SDRAM, QDRII+/QDRII SRAM,
and RLDRAM II interfaces, while Arria? GX devices support DDR2 and
DDR SDRAM interfaces. Applications with these memory interfaces
include PCs, embedded processing, image processing, storage,
communications, and networking.
