DDR3 interface provides full support for the DDR3 interface, compatible with JESD79-3F specification and DFI-version 2.0 or higher Specification Compliant. Through its DDR3 compatibility, it provides a simple interface to a wide range of low-cost devices. DDR3 IP is proven in FPGA environment. The host interface of the DDR3 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.
