Curtiss-Wright, Green Hills, and Harris are First to Demo FACE™-Conformant Software Running Simultaneously on x86 and Power Architecture Platforms

Sept. 18, 2018

U.S. Army FACE™ Technical Interchange Meeting (TIM), HUNTSVILLE, Alabama (Booth #22) – Sept 18, 2018 –Curtiss-Wright’s Defense Solutions division, in collaboration with Harris Corporation and Green Hills Software® (GHS), has publicly demonstrated the first working example of a FACE-conformant operating system (OS) and FACE-conformant software application running simultaneously on two completely different processor infrastructures (Intel® and NXP® Power Architecture®). The demo featured Harris’s popular FACE-conformant FliteScene Digital Moving Map software running on top of GHS’s industry-leading and FACE-conformant INTEGRITY-178 tuMP™ real-time multicore OS.

The commercial off-the-shelf (COTS) module hardware solutions showcased in the demonstration included Curtiss-Wright’s NXP Power Architecture QorIQ™ Quad-core AltiVec™-enabled T2080 processor-based VPX3-152, a DO-254 safety-certifiable 3U OpenVPX single board computer (SBC), and the VPX3-1258, a 4th Gen Intel® Core™ i7 (Haswell) processor-based 3U OpenVPX SBC. The demonstration of two completely different hardware instantiations running the exact same OS and application software highlighted how the use of a FACE-conformant software infrastructure enables operators of different aircraft types to run common capabilities on hardware solutions that have been size, weight, power and cost (SWaP-C)-optimized for each individual platform.

“We are very proud, in collaboration with Green Hills and Harris, to have shown the first public demonstration of FACE-conformant software running simultaneously on heterogeneous processor architectures,” said Lynn Bamford, Senior Vice President and General Manager, Curtiss-Wright Defense Solutions division. “The promise of FACE is to deliver greater flexibility to military system designers while simplifying their logistics, boosting interoperability, and eliminating costly proprietary solutions. This successful demonstration helps advance that promise from theory to practical reality.”

Today, as 3U VPX becomes the industry standard (replacing the ubiquitous 6U VME form factor), leading COTS vendors offer a wide range of 3U OpenVPX processors that are based on Intel x86, Power Architecture, and Arm architectures (including DO-254 safety-certifiable solutions) that can be rapidly deployed in a rugged chassis for applications onboard fighter jets, cargo aircraft, and helicopters.  The availability of GHS’s FACE-conformant INTEGRITY-178 tuMP OS to support all of these processor types provides system designers with the ability to select the optimal mix of processors and OS when integrating a FACE-aligned, SWaP-C-optimized system.

About FACE

FACE is a government-industry software standard and business strategy for acquisition of affordable software systems that promotes innovation and rapid integration of portable capabilities across global defense programs. Certon, an affirmed FACE Verification Authority, completed all verification activities on the FliteScene software in accordance with the FACE Technical Standard and FACE Conformance Policy, resulting in Harris receiving FACE Conformant Certificate #2. Certon was also the FACE verification authority for Green Hills’ RTOS.

About Green Hills Software INTEGRITY-178 tuMP RTOS

The INTEGRITY-178 tuMP, the first true multicore operating system to conform to the FACE Technical Standard, is conformant to the FACE 2.1.1 Technical Standard. It conforms to both the FACE Safety Base and Security Profiles for the C, C++ and Ada programming languages. The RTOS has successfully met the DO-178 DAL A certification objectives multiple times across several different multicore SOC architectures, each of which featured a different core design. It is available for all of Curtiss-Wright’s DO-254 safety-certifiable products including its Power Architecture, Intel, and Arm-based SBCs. (

About the VPX3-152 Single Board Computer

Curtiss-Wright’s VPX3-152 is a DO-254 DAL A safety-certifiable COTS SBC. The rugged 3U OpenVPX module features NXP's QorIQ® T2080 multicore SOC. For safety-certifiable SBC designs, the QorIQ T2080, a quad-core AltiVec™-equipped 64-bit Power Architecture SOC processor, has emerged as a de facto standard thanks to its support from a wide range of proven and trusted OS vendors, including Green Hills Software, Lynx Software Technologies®, SYSGO®, and Wind River®. Curtiss-Wright designed the 3U VPX VPX3-152 from the ground up to be cost-effective and to support DO-254 DAL A safety certifiability for critical defense and aerospace avionics applications. Designed around the NXP T2080 SOC, the VPX3-152 takes full advantage of the T2080’s features to reduce the chip count and complexity, which lowers the cost and the risk associated with the safety certification effort. Designed for use in size, weight, and power (SWaP)-constrained applications, the VPX3-152’s compact 3U design is ideal for use in a wide range of C4ISR applications deployed in harsh environments, especially those that require safety-certifiable DO-254 hardware and DO-178C software.
