DDR2 interface provides full support for the DDR2 interface, compatible with JESD79-2F specification and DFI-version 2.0 or higher Specification Compliant. Through its DDR2 compatibility, it provides a simple interface to a wide range of low-cost devices. DDR2 IP is proven in FPGA environment. The host interface of the DDR2 can be simple interface or can be AMBA AHB, AMBA AHB-Lite, AMBA APB, AMBA AXI, AMBA AXI-Lite, Tilelink, OCP, VCI, Avalon, PLB, Wishbone or Custom protocol.
