Green Hills and Curtiss-Wright collaborate on safety-critical embedded computing for avionics

Summary points:

• Green Hills Software and Curtiss-Wright partner to deliver open-systems multicore embedded computing solutions for safety- and airworthiness-certified avionics.
• Combines Curtiss-Wright’s V3-1222 3U VPX board powered by 13th Gen Intel Core i7 processors with Green Hills’ FACE-certified INTEGRITY-178 tuMP RTOS for optimized multicore performance.
• Supports DAL A certification goals for mission-critical military, commercial aviation, and emerging eVTOL applications.

SANTA BARBARA, Calif. – Green Hills Software in Santa Barbara, Calif., is teaming with the Curtiss Wright Corp. Defense Solutions Division in Ashburn, Va., to provide open-systems multicore embedded computing for safety-critical and airworthiness-certified avionics.

The companies are combining the Curtiss-Wright SOSA aligned V3-1222 3U VPX processing module with the Green Hills FACE-certified INTEGRITY-178 tuMP real-time operating system (RTOS) software.

The Curtiss-Wright V3-1222 embedded computing board features the 13th Gen Intel Core i7 processor, which combines six performance-cores and eight efficient-cores, along with integrated Intel Iris Xe graphics-all in a single-slot 3U VPX footprint.

The Green Hills INTEGRITY-178 tuMP safety-critical RTOS supports bound multi-processing (BMP) and symmetric multi-processing (SMP) to enable developers to assign specific workloads to optimal core types to maximize throughput and determinism.

Parallel workloads

In addition to running several workloads in parallel, INTEGRITY-178 tuMP enables a multi-threaded safety-critical workload to execute across several cores. Together, these technologies support system developers targeting the highest Design Assurance Level (DAL A) certification objectives, including compliance with A(M)C 20-193/DO-178C and A(M)C 20-152A/DO-254 guidance.

This solution is engineered for military applications like tactical radar, flight-control computers and sensor fusion; commercial aviation applications like digital cockpit systems, primary and multifunction displays, and enhanced flight vision systems; and air-mobility applications like autonomous flight control, safety-critical robotics, and electric vertical takeoff and landing (eVTOL) aircraft.
