The BittWare XUPP3R PCIe accelerator board built with a Xilinx UltraScale+ FPGA is designed for high-performance, high-bandwidth, and reduced latency applications demanding massive data flow and packet processing.
The board offers extensive memory configurations supporting up to 256 GBytes of memory, sophisticated clocking and timing options, and four front panel QSFP cages, each supporting up to 100 Gbps (4×25) – including 100GbE. The XUPP3R also incorporates a Board Management Controller (BMC) for advanced system monitoring, which greatly simplifies platform integration and management. All of these features combine to make the XUPP3R ideal for a wide range of data center applications, including network processing and security, acceleration, storage, broadcast, and SigInt.
The UltraScale+ VU13P offers up to 3.8 million logic elements. This power density makes thermal management difficult, but BittWare supports these high FPGA loads with the Viper platform, which includes 512 GBytes DDR4, and 4x 100 Gbps Ethernet.
The Xilinx UltraScale+ FPGAs are built on 16 nm process technology using 16FF+ FinFET 3D transistors to offer higher performance per watt than previous generations. Virtex UltraScale+ devices feature up to 128x 32.75 Gbit/s transceivers, which enable 400GbE, 100GbE, and 25GbE. The UltraScale+ FPGAs offer programmable system integration with over 400 Mb of on-chip memory, integrated 100G Ethernet MAC with RS-FEC and 150G Interlaken cores, and IP blocks for PCIe Gen3 x16 and Gen4 x8. Up to 11,904 DSP slices provide high-level DSP compute performance.
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.
The XUPP3R provides a variety of interfaces for high-speed serial I/O as well as debug support. Four QSFP28 cages are available on the front panel, each supporting 100GbE, 40GbE, four 25GbE, or four 10GbE channels, for a total of up to 400 Gbps of bandwidth. The four QSFPs can also be combined for 400GbE. The QSFP channels are connected directly to the UltraScale+ FPGA via 16 transceivers. The QSFP cages can optionally be adapted for SFP+.
A Gen3 x16 PCIe interface connects to the FPGA via 16 transceivers. An optional serial expansion port provides a 20x transceiver port connection to the FPGA and can be used to add serial memory, such as Hybrid Memory Cube (HMC) or an additional PCIe interface. The expansion interface also provides 14 GPIO signals.
A USB 2.0 interface is available for debug and programming support. The board also supports timestamping with provision for a 1 PPS and reference clock input.
BittWare’s exclusive SEP (serial expansion port) allows the XUPP3R to be expanded for an additional PCIe Gen3 x16 slot, additional 4 QSFPs, or connection between two XUPP3Rs.
The XUPP3R features four DIMM sites that support standard DDR4 DIMMs and proprietary QDR-II+ RDIMMs. Each DIMM site supports up to 128 GBytes of DDR4 with optional ECC or up to 576 Mbits QDRII+ (2x 288Mbit banks x18). Additional on-board memory includes Flash with factory default and support for multiple FPGA images.
In addition to standard active fan and heatsink cooling, the XUPP3R offers two passive options, standard and our new advanced passive cooling using heat pipes.
This boards‘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.
BittWare offers complete software support for this card 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.
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.
