GDDR3 Controller IIP

GDDR3 interface provides full support for the GDDR3 interface, compatible with GDDR3 specification and DFI-version 4.0 or 5.0 Specification Compliant. Through its GDDR3 compatibility, it provides a simple interface to a wide range of low-cost devices. GDDR3 IIP is proven in FPGA environment. The host interface of the GDDR3 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.
