SANTA BARBARA, Calif. Green Hills Software announced that the INTEGRITY-178 tuMP multicore real-time operating system (RTOS) is the first operating system to be part of a multicore certification to RCTA/DO-178C and CAST-32A. According to the company, the certification is part of a Technical Standing Order (TSO) authorization for CMC Electronics’ PU-3000 Avionics Computer, and the TSO submission included evidence of meeting all CAST-32A requirements for multicore processors. 

Guilty until proven innocent – that is how the U.S. Department of Defense (DoD) treats the safety-certification process for military avionics systems, and the software portion of these systems is no exception. Certifying DO-178 in avionics software is a detailed process by which the safety and security of the software is determined to be acceptable to fly. The certification process itself is still a work in progress: Having already undergone revisions since its conception in the late 1980s following the emergence of supplemental software in aviation, DO-178 and other safety-certification standards for military and commercial avionics are being challenged to keep pace with digital innovation.

SANTA BARBARA, Calif. Green Hills Software announced that its INTEGRITY-178 Time-Variant Unified Multi-Processing (tuMP) RTOS is being used by Collins Aerospace to meet the NSA's Raise the Bar (RTB) initiative for Cross Domain Solutions (CDS).

SANTA BARBARA, Calif. Green Hills Software announced that its INTEGRITY-178 tuMP real-time operating system (RTOS) will be used in Terma North America's (Arlington, Virginia) next-generation family of electronic warfare (EW)  controllers [the AN/ALQ-213(v5)] as part of Terma's recent $306 million indefinite-delivery/indefinite-quantity (ID/IQ) contract from the Defense Logistics Agency (DLA)--Aviation (Warner Robins, Georgia).  

SANTA BARBARA, Calif. Green Hills Software, company specialzing in high-assurance operating systems, announced that its INTEGRITY-178 Time-Variant Unified Multi-Processing (tuMP) RTOS was selected by the U.S. Army for the operating system upgrade to the Improved Data Modem (IDM-401) program.

Security-critical applications, such as cross-domain solutions (CDS), require a secure, trusted platform on which to execute, spanning software, firmware, and hardware. The lowest layer that the application interacts with directly is a trusted operating system (OS). Trust in the OS is dependent on two factors: its robustness from a security perspective, and assurance that the OS was both loaded and configured correctly and never tampered with. OS trust also depends partly on trusted pre-OS functionality, such as secure boot firmware that executes before the OS.

SANTA BARBARA, CA — July 1, 2020 — Green Hills Software, the worldwide leader in high-assurance operating systems, announced today that it has extended its solution for DO-178C Level A multicore interference mitigation to Arm Cortex-A72 processor cores.
