C-5M Super Galaxy Cockpit to be Upgraded with Multicore Avionics Computer Running INTEGRITY-178 tuMP

SANTA BARBARA, Calif., July 28, 2022 /PRNewswire/ — Green Hills Software announced today that its INTEGRITY®-178 tuMP™ safety-critical real-time operating system (RTOS) will be used in the Replacement Multi-Function Controls and Displays (RMCD) of the C-5M Super Galaxy transport aircraft. The INTEGRITY-178 tuMP will run on the PU-3000 multicore avionics computer from CMC Electronics, which will be combined with the VDT-1209 video display terminal from Intellisense Systems to form the entire C-5M cockpit display system, including the primary flight displays. .

The C-5M Super Galaxy is a strategic transport aircraft and is the largest aircraft in the Air Force inventory. Its primary mission is to transport cargo and personnel for the Department of Defense. The C-5M uses a multi-function smart display to provide the pilot, copilot, and flight engineers with basic flight and navigation information. The RCMD will use three PU-3000 multicore avionics computers with graphics processing modules installed to drive the new large-format displays. PU-3000 will also host the C-5M operational flight program. The PU-3000 is the first multicore avionics computer to receive TSO authorization by meeting DO-178C and CAST-32A multicore goals to the highest Design Assurance Level (DAL A).

The INTEGRITY-178 tuMP safety-critical RTOS from Green Hills Software is the only operating system to be part of a successful multicore certification to the DO-178C and CAST-32A goals. INTEGRITY-178 tuMP is a multicore RTOS with support for running a multi-threaded DAL An application with multiple processor cores in symmetric multi-processing (SMP) or bound multi-processing (BMP) configurations , as well as supporting more basic asymmetric multi-processing (AMP). INTEGRITY-178 tuMP is the first RTOS to be certified as compliant with the FACE Technical Standard, edition 3.0, and it is the only RTOS with multicore interference mitigation for all shared resources, enabling the system integrator to achieve -ot the purposes of CAST-32A. Multicore interference occurs when more than one processor core attempts to simultaneously access a shared resource, such as system memory, I/O, or an on-chip interconnect. To further facilitate CAST-32A compliance, Green Hills provides bandwidth allocation and monitoring (BAM) functionality in the INTEGRITY-178 tuMP that ensures critical applications get their allocated access to shared resources to meet their required deadlines, reducing integration and certification. risk. Together, the flexible multi-processing architecture and multicore interference mitigation enable a system integrator to maximize multicore processor performance while meeting safety and security requirements.
