Altera offers a PCI Express to DDR2 SDRAM reference design that demonstrates the operation of Alteras PCI Express (PCIe) MegaCore® product. This reference design provides an interface between the Altera® PCIe MegaCore function and a 64-bit, 256-Mbyte DDR2 SDRAM memory that enables access to external DDR2 SDRAM memory through the PCIe bus. It also represents an example of a typical user application that interfaces to the system side of the Altera PCIe MegaCore function.
