  • Cobra High Speed RecorderCobra High Speed Recorder

    Modular & Flexible

    The Cobra High Speed Recorder is a unique solution for high speed data recording and playback at a rate of up to 20 GB/s (160 Gbps). The system utilizes the PXI Express architecture to provide a modular, flexible solution that can be customized to nearly any requirement. The main recording engine, Cobra, is a PXIe board with high speed RAM and a high performance Xilinx FPGA. This board manages the data movement to and from storage devices and also provides optical fiber channels for high speed data input or output. The Cobra board can be used alone or in concert with additional Cobra boards.

    A typical system configuration will include an Intel processor based controller, one or more Cobra boards, and one or more SSD based storage boards. The PXI Express backplane allows numerous configurations and combinations of storage and recorder boards to match nearly any requirement. Extended systems can also employ an additional chassis to provide additional storage capacity if desired.

    Peer-to-Peer PCI Express

    Conduant’s StreamStor® architecture provides the capability to move data on the PCI Express fabric using Peer-to-Peer techniques. This allows direct hardware data streaming from A/D or other PCI Express sources to or from the data storage without being impaired by system bottlenecks. The system can also accept data from multiple PCI Express sources simultaneously.


    The Cobra High Speed Recorder can operate independently from a host computer with command/control performed over a network connection. Control can also be automated from a software application using the StreamStor® software API on a network connected computer. A cabled PCI Express option provides connectivity to a host computer for command/control and/or high-speed data access. The cabled PCI Express option provides a 64 Gbps link that can be optionally extended to support long distance links using a PCI Express fiber optic cable.

    Solid State Storage

    The standard storage devices used in the Cobra High Speed Recorder system are M.2 NVMe PCI Express solid state drives. These devices are installed with up to 4 per PXI Express slot using the DM-4M.2 Storage Unit. These drives are available in capacities up to 4 TB each, with even higher capacities expected in the future. The use of solid state drives provides consistent performance even with high levels of shock and vibration. Current standard configurations support up to 128 TB of storage in a 4U 22″ deep chassis. Check with your Conduant sales representative for the latest available storage offerings compatible with the Cobra system.

    High Speed Serial (Optical)

    The Xilinx FPGA on the Cobra board optionally includes up to 24 channels (48 fibers) of high speed optical and can be configured to support many different high speed serial protocols. The protocols possible over these interfaces include ODI (Optical Data Interface), Interlaken, Serial FPDP, and Aurora. Other interfaces can be added according to customer requirements.

    The optical interfaces can also be used to extend the recorder performance. For example, an ODI recorder is capable of 160 Gbps using 4 recorders and a 12 x 14.1 Gbps interface. The optical interface provides a high speed data path that is daisy chained to each recorder so that the speed capability is aggregated across the cooperating recorders.

    The 24 optical fibers can be tailored to customer requirements by bonding channels to create higher speed channels or used independently to record large numbers of slower channels. The Xilinx FPGA also allows Conduant the flexibility to customize an implementation for a particular protocol.

    Trigger/Sync Capability

    The Cobra hardware is connected to the PXI Express backplane instrumentation signals and also has front panel signal connectors. These signal sources can be adapted to customer requirements to provide unique capabilities required for a customer application—triggers, event marking, etc.

    Software API

    The included software development kit (SDK) includes support for .NET development environments. This includes languages such as C#, Visual Basic, and C++ CLI. The SDK also includes a complete “C” based interface to facilitate usage of nearly any programming language. This includes programming environments such as LabVIEW and MATLAB.

    The SDK includes support for features such as wrap mode (circular buffer) for very long duration recording, playback looping, and multiple recording (file) management. Additional features are added regularly and the software can be customized as needed.



  • Sustained Recording and Playback

    The StreamStor® Amazon Express storage controller provides recording and playback capability at more than 600 MB/s. Support is provided for up to 16 SATA disk drives for a maximum total capacity of 16 terabytes (using 1 TB disk drives). With the appropriate disk drives, the Amazon Express controller can provide more than seven hours of recording or playback capability at 600 MB/s.

    Using direct card-to-card transfers over the PCI Express bus or direct data input from available external digital interfaces, the Amazon Express provides reliable and sustained recording or playback without the threat of host software or OS bottlenecks. With an on-board PowerPC processor, real-time operating system, and StreamStor® data engine, the Amazon Express operates independently of the host to provide guaranteed performance without interruption.

    The Amazon Express has been specifically designed to support high-speed data streaming applications such as:

    • Digital Signal Processing (DSP)
    • High speed data acquisition
    • Radar and sonar
    • Medical imaging
    • Satellite download
    • High resolution video
    • Waveform generation

    The Amazon Express is a full-size PCI Express card that can be installed in nearly any standard PC with open PCI Express slots. The controller also supports advanced StreamStor® functionality including circular recording (wrap mode) and direct recording from PCI, PCI-X, and PCI Express sources.

    The StreamStor® SDK provides drivers and a complete programming library for Windows or Linux operating systems. A recording application and many example programs are included. Advanced features such as circular buffer, partitioning, multi-channel, etc. are available through functions in the StreamStor® software library. Contact your Conduant sales representative for more information on other available features and software.

    Storage Media

    The Amazon Express supports nearly any SATA disk drive on the market. This includes notebook disk drives (2.5″), desktop disk drives (3.5″), rugged hard drives, and solid-state (flash) drives. Amazon Express is also available in system configurations ranging from portables to large rack-mount systems capable of housing multiple recorders. Contact your sales representative for more information.


  • The StreamStor® SFPDP mezzanine board can be used with compatible StreamStor® controllers to provide direct data input from Serial FPDP (Serial Front Panel Data Port) or other optical data protocols. When combined with a StreamStor® controller such as Amazon, this interface can provide data input performance of up to 500 MB/s.

    With its four independent optical ports, the SFPDP mezzanine board can support recording of up to four incoming data streams. The board can be ordered with support for data rates from 1.06 to 2.5 Gbps and wavelengths of 850nm or 1300nm to support cable lengths of up to 25km. The board uses industry standard LC optical connector style for easy connection to compatible data sources.

    Standard support is provided for the Serial FPDP protocol (ANSI/VITA 17.1-2003), which is a highly specialized protocol optimized for maximum data rates and minimum overhead. With all packet formation and management performed by the hardware, there is no latency or other delays to affect data transmission performance. Combined with StreamStor® storage controllers, this data interface provides a reliable and sustainable high speed data recording and playback solution. Other protocols can be supported with updates to the on-board Altera Stratix FPGA hardware. The flexibility of programmable logic makes it possible to customize the hardware to each unique application.

    Serial FPDP

    The serial FPDP protocol is defined by the ANSI / VITA 17.1-2003 standard. The standard is available for a small fee online at Conduant Corporation also provides hardware source code to customers who wish to implement Serial FPDP on their own FPGA-based circuit boards.
