The BittWare A10SA4 PCIe accelerator board built with a Altera Arria 10 GX 1150 FPGA is well suited to large FPGA loads in the data center.
The A10SA4 supports the Open Computing Language (OpenCL™) programming model, which enables a high-level software-like development flow, which greatly simplifies FPGA development. Development tools for OpenCL include Intel’s SDK for OpenCL and BittWare’s OpenCL Developer’s Bundle.
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 1.9 million logic elements. This power density makes thermal management difficult, but BittWare solves this problem with the Spider platform for large FPGA loads.
This board is designed with BittWare’s Spider platform, which is a low-profile PCIe platform optimized for thermal performance. The Spider platform combines a low-profile PCIe form-factor for high density, the ability to run larger loads, and a robust passive heatsink option designed for servers.
The A10SA4 is enabled for high-speed networking with an optional QSFP interface supporting 40GbE or four 10GbE channels. The QSFP SerDes channels are connected directly to the Arria 10 FPGA, thus removing the latency of external PHYs. A 1 PPS input allows precise timestamping.
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. All examples are available for download on BittWare’s developer website.
