NetFPGA-SUME™ Reference Manual
Revised April 11, 2016
This manual applies to the NetFPGA-SUME rev. C
Overview
Powered by Xilinx's Virtex-7 XC7V690T
FPGA, the NetFPGA-SUME is an ideal
platform for high-performance and
high-density networking design.
32 GTH serial transceivers have been
used to provide access to 8 lanes of
end-point PCI-E (Gen3 x8), 4 SFP+
(10Gbps) ports, 2 SATA-III ports
(6Gbps), and 18 data-rate-adjustable
GTH ports through a HPC-FMC
connector and a QTH connector.
Wide high-speed memory interfaces in the form of three 72 MBit QDRII+ SRAMs with 36 bit buses and two 4GB
DDR3 SODIMMs with 64 bit buses provide an ideal memory solution for common networking applications.
