Kontron VXFabric™ Whitepaper - PCI Express Switch Fabric for High Performance Embedded Computing

Version 2

     

    The advent of VPX opens a new era of rugged embedded computing. VPX allows board

    computers to move away from decades of parallel bus architectures on the

    backplane, with a little help from 1Gigabit Ethernet, and implement high speed

    serial link point-to-point connections between boards. Now that the ecosystem

    is defined for board sizes, connectors and signaling for 10 to 20 years, let's take

    a closer look into building the next generation board computers and understand

    how data will flow in this new architecture.

    With VPX connectors and backplanes, multi-gigahertz signals allow building

    computers where the full data plane bandwidth is no longer shared between

    boards. Amongst serial link technologies available today, Peripheral Component

    Interconnect Express (PCIe) is poised to bring many military applications to a

    new level. High Performance Computing is the first domain to benefit from the

    tenfold increase in I/O bandwidth between computing boards that VPX offers.

    This enables a new breed of unparalleled applications for sensor data processing

    platforms used in radar, sonar, and general imaging.

     

    But now, as hardware guidelines are set, OEMs and developers have to search

    for the ideal communication protocols. With all the advantages of current standards

    such as PCI Express, Gigabit Ethernet, Serial Rapid IO and many others that can

    be used for intra-system communications, this is not an easy task. The challenge

    for OEMs is to find an easy to use, yet fast and low latency communication protocol.
