Part Number : DO-254 AXI 7-Series
Short Desc. : DDRx (Limited) 1.00a
Overview :

The DO-254 AXI 7-Series DDRx (Limited) 1.00a uses the Xilinx®-7 Series FPGAs memory interface solutions to provide high-performance connections to DDR3 and DDR2 SDRAMs.  Xilinx®-7 Series FPGAs memory interface solutions core is a combined pre-engineered controller and physical layer (PHY) for interfacing 7 series FPGA user designs and AMBA® advanced extensible interface (AXI4) slave interfaces to DDR3 and DDR2 SDRAM devices.  In the Embedded Development Kit (EDK), this core is provided through the Xilinx® Platform Studio (XPS) as the DO-254 AXI 7-Series DDRx (Limited) 1.00a IP located in the DO-254 IP library with a static AXI4 to DDR3 or DDR2 SDRAM architecture.
