NXP® Layerscape®-based VPX3-1703 SBC provides system integrators with compelling new option for architecting critical systems
ASHBURN, Va. – March 1, 2018 – Curtiss-Wright’s Defense Solutions division today launched a new era of safety-certifiable avionics embedded computing with the debut of the COTS industry’s first Arm processor based 3U OpenVPX™ single board computer (SBC) designed to support DO-254 DAL C (PLD to DAL A) requirements. The safety-certifiable VPX3-1703 SBC is based on the latest generation NXP® Layerscape® LS1043A Arm Quad-core A53 processor. This low-power card (14W to 21W depending on frequency and application) provides designers of safety-certified avionics systems with a compelling new alternative to traditional processor architectures, such as those based on Intel® or Power Architecture® devices.
Designed specifically to address DO-254 avionics applications, the VPX3-1703 is available with re-usable DAL C design artifacts that help speed and ease the system certification process while greatly reducing program risks and costs. The VPX3-1703’s LS1043A processor, supported by NXP with a 10+ year life cycle, features four low-power Arm A53 cores that provide a superior balance between performance, power, and cost for deployed defense and aerospace systems. What’s more, because A53 cores are well known and field-proven, they provide an ideal, high-confidence pedigree for demanding and critical safety-certifiable applications, such as avionics and motor/engine control. The fully rugged VPX3-1703 is ideal for use in mission computers, as well as general purpose SBC applications, both safety-certifiable and non-safety-certifiable.
For many DO-254 safety-critical applications, system designers prefer to architect a mix of “dissimilar” processor types in order to reduce the risk of system failure. A specific software glitch is significantly less likely to appear on two or three different processor architectures simultaneously. The availability of a new family of Arm processor-based SBCs provides system designers with a powerful alternative for architecting dissimilar processor-based safety-certified avionics solutions. Curtiss-Wright believes that the VPX3-1703 will also be the industry’s first Arm-based 3U OpenVPX SBC module designed to DO-254 requirements to ship to customers.
“Low-power Arm processing technology delivers a compelling alternative for embedded single board computer designs that have typically depended on traditional processor technologies,” said Lynn Bamford, Senior Vice President and General Manager, Defense Solutions division. “For next-generation safety-certifiable SBCs, Arm provides a perfect balance between compute power and low-power dissipation, both critical for many deployed aerospace and defense platforms. Curtiss-Wright sees a great future for Arm in rugged embedded computing and we plan to expand our product family with a wide range of offerings and form factors in the near future. We look forward to leading the industry into an exciting future with Arm.”
The VPX3-1703 is the first in a new family of Arm-based 3U based OpenVPX modules from Curtiss-Wright. In addition, to ease integration of the VPX3-1703 with legacy modules, Curtiss-Wright plans to announce new OS and software driver support for a wide variety for products, including its VPX3-717 and VPX3-719 DO-254 and DO-178C Safety-Certifiable 3U OpenVPX Graphics Processors, and the VPX3-611 DO-254 Safety-Certifiable MIL-STD-1553B and ARINC 429 I/O Module.
Software support for the VPX3-1703 includes Curtiss-Wright’s U-Boot firmware, providing a comprehensive suite of system debug, exerciser, and update functions, BIT, and non-volatile memory sanitization function. A Wind River VxWorks® 7 and a Linux® Board Support Package (BSP) and Driver Suite will be available. Safety-certifiable OSs will be available from Curtiss-Wright’s software partners.
