    Truly rugged and proven reliable: VITA 47 and beyond

    All vendors of commercial off-the-shelf (COTS) hardware intended for use in harsh defense and aerospace environments insist that their products are reliable as well as rugged. But without a consistent baseline for comparison, it’s almost impossible for system integrators to objectively confirm whether one COTS product is more reliable than another. The VITA 47 standard gives system integrators just such a baseline as it is an American National Standards Institute (ANSI) standard.

  • Taking the complexity out of PCI Express configuration to optimize HPEC system design

    Performance is all about eliminating bottlenecks to minimize latency and maximize throughput. Today’s high-performance embedded computing (HPEC) systems integrate powerful processing subsystems, each of which might be a fully functional processing node needing to share data with other processing nodes. To maximize overall system performance requires the fastest, most efficient processor-to-processor data paths. With VPX, embedded systems moved away from the VMEbus shared parallel bus model.

  • Long live VME!

    While the “V” in “VME” actually stands for “Versa” (as in “Versa Module Eurocard”), it could arguably also stand – especially in the defense and aerospace commercial off-the-shelf (COTS) market – for “venerable.” For the decades prior to the advent of the VPX architecture in 2006, VME was unquestionably a de facto board standard for rugged open architecture systems. Today, there are thousands of VME boards installed in the field and untold millions of dollars invested in hardware and systems software currently used on those deployed systems.
