On-Board Memory

The development board has the following memories available for system design.

A 204-pin SO-DIMM DDR3 module with 2.133 Gb/s performance.

To use as the primary off-chip memory for all applications. This supplements the
on-chip BRAM.

To serve as a demonstration of the embedded DDR3 controller capability.

A DDR3 device (2 Gb @ 1066 MHz) soldered on the board which you can use at 2.133
Gb/s performance.

Two RLDRAM3 (each 16 Mb x 36 for a total of 576 Mb @ 1066 MHz)

A QDR2+ device (2 Mb x 36 = 72 Mb @ 633 MHz) which you can use for high-
bandwidth, low-latency, random-access requirements such as classification and policy
lookup in networking applications.

An SPI Flash device which you can use to store configuration bitstreams on board.

On-Board Controller

The development board comes equipped with an on‐board, Atmel ATmega2560 AVR
microcontroller. You can use this microcontroller to perform the following tasks:

Control power sequencing of the board and any connected peripherals.

Measure the temperature captured via the on‐chip temp diode of the HD1000 FPGA.

Monitor power consumption of some of the key functional blocks.
