The Safest and Most Secure RTOS and Tools
Green Hills Software offers the safest and most secure real-time operating systems (RTOS) and development tools for aerospace and defense. Our safety and security pedigree goes back to 1997 with the Boeing B1-B avionics upgrade and the Sikorsky Helicopter S-92 Avionics Management System from Rockwell Collins, which was later certified to DO-178 DAL A. Since then, Green Hills Software products have been deployed on almost every commercial and military aircraft. Our in-house group of certification experts has provided certification evidence for over 100 safety and security certifications across all the key processor architectures, reducing time, cost, and risk of certification.

The INTEGRITY-178 tuMP real-time operating system (RTOS) provides unique benefits for safety and security-critical systems in aerospace and defense systems. For DO-178C airborne safety applications, INTEGRITY-178 tuMP is the only RTOS that supports multi-processing of ARINC 653 partitions across multicore cores in symmetric multi-processing (SMP) and bound multi-processing (BMP) mode. It is also the only RTOS to provide a general solution to multicore interference mitigation, as described in the CAST-32A position paper. That resulted in INTEGRITY-178 tuMP being the first and only RTOS to be part of a multicore certification to DO-178C and CAST-32A.” Managing the shared resource contention that causes multicore interference can benefit all types of real-time systems by decreasing worst-case execution times.
For security-critical applications, INTEGRITY-178 is the only commercial operating system certified to Common Criteria EAL6+ and NSA High Robustness, and INTEGRITY-178 tuMP extends that pedigree to multicore processors. High robustness enables hosting multi-level security (MLS) applications, and INTEGRITY-178 tuMP is the only commercial RTOS capable of hosting cross-domain solutions (CDS). INTEGRITY-178 tuMP is also the only RTOS to be part of a system certified to NSA’s new “Raise the Bar” standards for CDS systems.There is no reason to choose between safety and security when you can have the best of both in the same solution with the INTEGRITY-178 tuMP RTOS.
Green Hills Software is committed to open standards in support of a Modular Open Systems Approach (MOSA). As a founding member of the FACE™ Consortium, Green Hills Software is committed to certification of conformance to each update to the FACE Technical Standard. The INTEGRITY-178 tuMP RTOS was the first RTOS to be certified to the current Edition 3.0 as well as the previous Edition 2.1.1, and those certifications include both the safety and security profiles.

Industrial Safety and Commercial Security
When safety and security are important but not required to meet DO-178 or NSA High Robustness, the standard INTEGRITY RTOS provides best-in-class safety and security. Widely deployed in industrial, automotive, medical, and Internet-of-Things (IoT) applications, the INTEGRITY RTOS is an excellent match for command and control, sensor processing, electronic warfare, data recording, vetronics, and fire control applications.
