Bittware XUPVVH, Xilinx UltraScale+, 4x QSFP, 256 GB – Sky Blue Microsystems GmbH

Bittware XUPVVH | Ultra high-speed network interface | Xilinx UltraScale+ FPGA | 4x 100GbE | 460 GBps memory bandwidth | 256 GB DDR4

The BittWare XUPVVH PCIe accelerator board built with a Xilinx UltraScale+ VU35P/37P FPGA is well suited to high density data center applications that demand high memory bandwidths.

The UltraScale+ avoids I/O bottlenecks with integrated High Bandwidth Memory (HBM2) tiles on the FPGA that support up to 8 GBytes of memory at 460 GBytes/sec.

The UltraScale+ VU37P offers up to 2.8 million logic elements. This power density makes thermal management difficult, but Bittware solves this problem  with the Viper platform.

Xilinx UltraScale+ 3/4-Length PCIe Board

Viper Platform

BittWare’s Viper platform uses advanced computer flow simulation to drive the physical board design in a thermals-first approach, including the use of heat pipes, airflow channels, and arranging components to maximize the limited available airflow in a server. Viper boards are passive by default, with active cooling as an option.

High-Speed Networking and I/O

The XUPVVH is enabled for high-speed networking with four front panel QSFP+ cages, each supporting 40/100GbE or four 10/25GbE channels.

Serial expansion is available through two UltraPort SlimSAS connectors (16x 24Gbps) that can be connected to a second PCIe interface, another XUPVVH, or other devices, including IBM’s POWER9 via OpenCAPI.

A utility header provides a 1GbE interface, a PPS input, and a USB interface for debug and programming support.


The board’s flexible memory configuration includes two DIMM sites that support DDR4 SDRAM and QDR. Memory card options include up to 128 GBytes of DDR4 with optional error-correcting codes (ECC) or up 576 Mbits QDR-II+ (2x 288Mbit banks x18).

The board also features flash memory for FPGA images.

Board Management Controller

The XUPVVH‘s advanced system monitoring subsystem features a Board Management Controller (BMC), which accepts Intelligent Platform Management Interface (IPMI) messaging protocol commands.

The BMC features include control of power and resets, monitoring of board sensors, FPGA boot loader, voltage overrides, configuration of programmable clocks, access to I2C bus components, field upgrades, and IPMI messaging.

Access to the BMC is via PCIe or USB. BittWare’s BittWorks II Toolkit also provides utilities and libraries for communicating with the BMC components at a higher, more abstract level, allowing developers to remotely monitor the state of the board.

BittWorks II Toolkit

BittWare offers complete software support for the XUPVVH with its BittWorks II software tools. The BittWorks II Toolkit serves as the main interface between the BittWare board and the host system. The Toolkit includes drivers, libraries, utilities, and example projects for accessing, integrating, and developing applications for the BittWare board.

FPGA Example Projects

BittWare offers FPGA example projects to provide FPGA board support IP and integration for its UltraScale+ boards. The example projects easily integrate with the Xilinx Vivado tools and illustrate how to move data between the board’s different interfaces. All examples are available for download on BittWare’s developer website.
