External Memory Interfaces
This section describes the development board’s memory interface support, signal
names, types, and connectivity relative to the Stratix V GX device.
The development board contains two types of external memory interfaces that utilizes
the top and bottom of the Stratix V GX device.
■ DDR3 Interface—3 GB of high-speed DRAM for packet storage and other
sequential access memory uses.
■ QDR II Interface—9 MB of quad-port SRAM for high-speed random access
applications such as lookup tables and packet inspection.

For more information about the memory interfaces, refer to the External Memory
Interface Handbook .
DDR3 Interface
The DDR3 interface consists of 12 DDR3 devices, each providing 256-MB with a 16-bit
data bus. The maximum target speed is 800 MHz DDR for a theoretical bandwidth of
over 51.2 Gbps per 32-bit port, or a total bandwidth of 307.2 Gbps for the full 192-bit
bus. The targeted Micron device is rated at 800 MHz with a CAS latency of 11.

The board will be adapted to support the 933 MHz devices from Micron as a drop in
replacement once they become available.
