Intel® Quad-Core Xeon® processor-based VPX3-1220 RTCA/DO-254 safety-certifiable COTS SBC supports Green Hills Software RTCA/DO-178B Level A certifiable multi-core RTOS

ASHBURN, Va. – August 14, 2018 -- Curtiss-Wright’s Defense Solutions division today announced that Green Hills Software’s field-proven INTEGRITY-178 tuMP safety- and security-critical multi-core real-time operating system (RTOS) was recently demonstrated on the Curtiss-Wright VPX3-1220 module, an RTCA/DO-254 Design Assurance Level (DAL) C safety-certifiable 3U OpenVPX™ single board computer (SBC). The rugged module features the Intel® Xeon® E3 processor (formerly known as “Kaby Lake”) and enables avionics system designers to rapidly integrate Commercial Off-the-Shelf (COTS) system solutions based on the INTEGRITY-178 tuMP RTOS. INTEGRITY-178 tuMP is the industry’s only multi-core RTOS that enables users to utilize all available compute power from the Xeon E3 processor’s quad cores, including its virtual cores, all based on deterministic, user-defined core and scheduling assignments. With its embedded Intel® Core™ technology design, the VPX3-1220 SBC brings unprecedented computing power to certifiable mission computing and critical airborne applications.

The VPX3-1220’s low-power mobile Xeon E3 processor, which is ideal for airborne applications, delivers high-performance, quad-core x86 processing with integrated graphics at 50% of typical power levels compared to previous Intel processor solutions. Paired with the INTEGRITY-178 tuMP operating system (OS), the SBC provides a compelling combination of hardware and software for system integrators that require optimal processing power and industry-leading size, weight and power (SWaP) benefits for their multi-core critical systems.

“Support for Green Hills’ INTEGRITY-178 tuMP multi-core RTOS on the VPX3-1220 SBC demonstrates Curtiss-Wright’s dedication to raising the performance bar for safety-certifiable avionics, while simplifying the complex DO-254/DO-178 safety certification process for our embedded avionics customers,” said Lynn Bamford, Senior Vice President and General Manager, Curtiss-Wright Defense Solutions division. “Our ongoing collaboration with trusted operating system vendors, such as Green Hills, enables us to deliver complete COTS-based, safety-certifiable hardware and software solutions to the embedded defense and aerospace market.”

For programs with DO-254 DAL A or DAL B requirements, or system designers seeking a Power Architecture®-based SBC, Curtiss-Wright offers the NXP® QorIQ® T2080-based VPX3-152, a DO-254 DAL A safety-certifiable 3U OpenVPX SBC that also supports INTEGRITY-178 tuMP. In addition, earlier this year, Curtiss-Wright announced support for the INTEGRITY-178 tuMP RTOS on its T2080 SOC-based VPX3-133 3U OpenVPX SBC. The VPX3-133, combined with INTEGRITY-178 tuMP, is ideal for rugged deployed applications that do not require DO-254 safety-certifiable hardware.

The VPX3-1220 and VPX3-152 are compatible with Curtiss-Wright’s entire safety-certifiable module portfolio, including the VPX3-717 and VPX3-719 safety-certifiable OpenVPX graphics processors, and the VPX3-611 safety-certifiable MIL-STD-1553B and ARINC 429 I/O Module.

About the VPX3-1220

Designed with RTCA/DO-254 in mind from the beginning of the development cycle, the VPX3-1220 is offered with an RTCA/DO-254 DAL C data artifact package to speed and ease the safety certification process. It is the industry’s first multi-core Intel Xeon-based SBC designed to meet DO-254 DAL C for use on safety-critical military and civil aerospace platforms. Delivering the highest possible processing performance while consuming low power, the VPX3-1220 is ideal for mission computing applications in SWaP-constrained aerospace and defense systems. Use of this SBC accelerates and simplifies the integration of Intel Xeon-class processing into demanding deployed applications, such as mission computing and image and display processing.

Leveraging the strong partnership between Curtiss-Wright and Green Hills Software, INTEGRITY-178 tuMP on the Xeon E3 processor-based VPX3-1220 provides avionics system integrators with support for the first true multi-core OS to conform to any version of the FACE Technical Standard. The RTOS conforms to both the FACE Safety Base and Security Profiles for the C, C++ and Ada programming languages. The INTEGRITY-178 tuMP multi-core OS meets all of the requirements defined in the current standard for ARINC-653, Supplement 4, which requires multi-core operation per Section 2 of the Supplement 4 standard, and defines support for “Multiple processes within a partition scheduled to execute concurrently on different processor cores,” and support for “Multiple partitions scheduled to execute concurrently on different processor cores.”

The INTEGRITY-178 tuMP RTOS has successfully met the DO-178 DAL A certification objectives multiple times across several different multi-core SOC architectures, with each SOC having a different core design. It also satisfies the CAST-32A Position Paper for multi-core interference mitigation. The combination of INTEGRITY-178 tuMP’s time-partitioned AMP and SMP capabilities, with support for multi-core interference mitigation, provides the industry’s best core utilization and overall SOC throughput. This enables the VPX3-1220 to deliver unmatched SWaP reduction.

The VPX3-1220 SBC is available now for both air-cooled and conduction-cooled environments.
