Since 1982, Green Hills Software has provided certified real-time operating systems and embedded development tools with the highest level of safety and security for defence applications. Currently deployed in dozens of aerospace platforms ranging from helicopters and tactical fighters to satellites and spacecraft, the INTEGRITY-178 tuMP RTOS is the world's only operating system to be part of a multicore TSO authorization to DO-178C/ED-12C DAL A and CAST-32A multicore objectives. To aid in multicore certification, the INTEGRITY-178 tuMP safety-critical RTOS includes unique bandwidth allocation and monitoring (BAM) functionality to mitigate multicore interference – not just measure it. That mitigation enables maximum utilization of multicore resources and further consolidation of mixed-criticality avionics onto a single multicore processor. The INTEGRITY-178 tuMP is certified conformant to the FACE™ Technical Standard 3.0 for safety and security profiles running on Arm, Intel, and Power Architectures.
