BittWare A10SA4 | Altera Arria 10 GX 1150 FPGA | 1150K logic elements | 1.3 TFLOPS | Optional QSFP for 40GbE or 4x 10GbE | 16 GBytes of DDR4 SDRAM with ECC (x72)

BittWare’s A10PL4 is a low-profile PCIe x8 card based on the Altera Arria 10 GX FPGA. The Arria 10 features high density and a power-efficient FPGA fabric. Included are high-speed transceivers, hard floating-point DSP blocks, and embedded PCIe x8 Gen3.

The board offers over 32 GB of memory, sophisticated clocking and timing options, and two front panel QSFP cages. The A10PL4 also incorporates a Board Management Controller (BMC) for advanced system monitoring, which greatly simplifies platform management. All of these features combine to make the A10PL4 ideal for a wide range of applications, such as network processing, cyber security, compute and storage, instrumentation, broadcast, and Signals Intelligence.

Built on 20 nm process technology, the Arria 10 FPGAs feature industry-leading programmable logic that integrates a rich feature set of embedded peripherals, embedded high-speed transceivers, hard memory controllers, and protocol IP controllers. Variable-precision digital signal processing (DSP) blocks integrated with hardened floating point (IEEE 754-compliant) enable the Arria 10 to deliver floating-point performance of up to 1.5 TFLOPS. The FPGA supports Gen3 PCIe x8 via a hard IP block and provides up to 1150K equivalent Les.

Development tools for OpenCL include Altera’s SDK for OpenCL and BittWare’s OpenCL Developer’s Bundle.

Intel Arria 10 GX Low Profile PCIe Board with Dual QSFP and DDR4

High-Speed Networking and I/O

The A10PL4 provides a variety of interfaces for high-speed serial I/O as well as debug support. Two QSFP cages are available on the front panel, each 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. The QSFP cages can optionally be adapted for SFP+.

The x8 PCIe interface provides 8 SerDes lanes to the Arria 10 FPGA. A USB 2.0 interface with built-in USB-Blaster is available for debug and programming support. The board also supports timestamping with an optional precision timing module, which features 1 PPS and reference clock inputs and outputs along with precision clock circuitry. The timing module option requires a full-height front panel.


The A10PL4 features up to 32 GBytes of DDR4 with optional error-correcting codes (ECC). Additional on-board memory includes flash memory with factory default and support for multiple FPGA images. An on-board PROM provides access to the board’s MAC ID.

Board Management Controller

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.

BittWorks II Toolkit

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.

FPGA Development Kit

BittWare’s FPGA DevKit provides FPGA board support IP and integration for BittWare’s Altera FPGA-based boards. The FDK includes FPGA components that provide preconfigured physical interfaces, infrastructure, and examples, drastically cutting development time and easily integrating into existing FPGA development environments.

Working example projects are available for each board which illustrate how to move data between the board’s different interfaces. Supported interfaces include DDR4, DDR3, DDR2, QDR2/+, PCIe, 10GbE, LVDS, SerDes, and Double Data Rate I/O. All example projects are available on BittWare’s Developer Site.
