Green Hills Software INTEGRITY-178B tuMP Multicore Operating System Selected by Northrop Grumman for the U.S. Marine Corps H-1 Mission Computer

SANTA BARBARA, CA — February 13, 2013 — Green Hills Software, the worldwide leader in high assurance operating systems, announced Northrop Grumman’s selection of the INTEGRITY®-178B tuMP multicore operating system for use in their Gen II Mission Computer for the U.S. Marine Corps UH-1Y and AH-1Z helicopter upgrades. The Northrop Grumman Technical Refresh Mission Computer hosts the INTEGRITY-178B Time-Variant Unified Multi Processing (tuMP) capabilities using a Freescale QorIQ® P4080-based single-board computer.

“The UH-1Y and AH-1Z are highly integrated combat helicopters that require mission computers with significant yet flexible computing capabilities, which can be updated to support specific configurations,” said Ike Song, vice president of Northrop Grumman’s Situational Awareness Systems business unit in Woodland Hills, Calif.

The Green Hills Software tuMP multicore operating system is the foundation for the Northrop Grumman open systems architectural concept, providing a multicore framework for integrating applications of different programming languages, portable operating environments, and assurance needs. The highly capable scheduling capabilities of INTEGRITY-178B tuMP uniquely permit Northrop Grumman to effectively utilize the eight cores of the Freescale QorIQ P4080.

“Green Hills Software is very pleased that Northrop Grumman has selected the INTEGRITY-178B tuMP RTOS,” said Dan O’Dowd, founder and chief executive officer of Green Hills Software. “Green Hills Software has developed the INTEGRITY-178B tuMP multicore operating system for customers such as Northrop Grumman who want to maximize utilization of a multicore processor using products from a supplier with a proven reputation for delivery of reliable safe and secure software.”

Green Hills Software’s INTEGRITY-178B tuMP multicore operating system builds upon a proven twelve-year service history and certification pedigree by incorporating multicore operating system capabilities, including support for AMP and SMP. tuMP defines groupings (called affinity groups) of how cores will be utilized by one or more applications, with the grouping of cores and applications being permitted to vary over time. Sets of affinity groups are then scheduled independently of other sets of affinity groups, permitting time-lines that closely correspond to application requirements, yet also permitting other sets of affinity groups to be developed that can make use of time windows where cores are not being utilized. Multiple schedule support further extends the tuMP scheduling capabilities, permitting tailoring of available applications and processor time resources based on the vehicles’ operational needs, such as flight or combat phase. INTEGRITY-178B tuMP extends partitioning support beyond single-core processors, ensuring this highly flexible capability can continue to be effectively used to host multiple applications while preserving resources for application growth without concern about future availability of new single-core processor designs.

Want early design analysis without simulation?

Sponsored by Siemens Digital Industries Software

Traditional verification methods are failing today's complex IC designs, which require a proactive, early-stage analysis approach. A shift-left methodology addresses IP block integration challenges and the limitations of traditional simulation and ERC tools. Insight Analyzer detects hard-to-find leakage issues across power domains, enabling early analysis without full simulation. Identify inefficiencies earlier to reduce rework, improve reliability, and enhance power performance.
