Curtiss-Wright and Green Hills Demonstrate Safety-Critical Operating System

Multi-core RTOS Frees Up All Available Computing Power

Curtiss-Wright Defense Solutions announced on 14 August that, in collaboration with Green Hills Software, it has demonstrated the latter’s INTEGRITY-178 tuMP safety- and security-critical real-time operating system (RTOS) on its own VPX3-1220 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, which is the industry’s only multi-core RTOS that enables users to use all available computing 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 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 RTOS, 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,” commented  Senior Vice President and General Manager, Curtiss-Wright Defense Solutions division, Lynn Bamford. “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 defence and aerospace market.”
