Green Hills Software Announces INTEGRITY Support for BAE Systems RAD750; Brings Proven Mission-Critical Real-Time Operating System to Premier Radiation-Hardened Computer for Space Applications.SANTA BARBARA, Calif. -- Green Hills Software, Inc., the leader in real-time operating systems (RTOS (1) (RealTime Operating System) An operating system designed for use in a real time computer system. See real time system, embedded system, process control and OS-9. ) and device software optimization Device Software Optimization is a concept promoted by Wind River Systems and CMP Publications at dso.com. It refers to a set of toolchains and analysis tools to develop and debug software for embedded systems. (DSO), today announced the immediate availability of a complete port of its INTEGRITY real-time operating system to the BAE Systems' RAD750(TM) radiation hardened PowerPC Processor and CompactPCI(R) single board computer. The combination of INTEGRITY and RAD750 yields the industry's most advanced hardware/software architecture for high reliability space systems. "We selected INTEGRITY because of its proven heritage in mission critical systems as well as its integration with Green Hills Software's powerful MULTI MULTI Multiple IDE tool set," commented Dave Stofko, Flight Systems Software Manager, Space Systems/Loral. "Coupled with the latest radiation-hardened hardware, this solution represents the state-of-the-art in space-based device software platforms." INTEGRITY RTOS INTEGRITY, the premier real-time operating system for use in mission critical systems, has been selected for use in space-based systems such as satellites as well as a wide variety of aerospace applications. According to leading industry analysts, INTEGRITY has demonstrated the highest growth in real-time operating system market share for the past 4 years. INTEGRITY's success is due to its advanced technological design, incorporating memory protection, guaranteed resource availability, field upgradeability, optimal real-time response, and the world's leading development tools integration with Green Hills Software's MULTI IDE. In addition, INTEGRITY is the only commercially developed real-time operating system to be certified with integrated modular avionics Integrated Modular Avionics (IMA) represent real-time computer network airborne systems. This network consist of a number of computing modules capable of supporting numerous applications of differing criticality levels.

In comparison, legacy real-time operating systems running on radiation-hardened computers have not taken advantage of the processor's memory management unit (MMU) at all, making the system susceptible to unforeseen interactions between software components, including memory corruptions, faults and denial of service A condition in which a system can no longer respond to normal requests.

As such, these systems require an operating system that can meet the highest levels of reliability and security while enabling in-space reconfiguration. INTEGRITY's microkernel design, virtual device drivers, and partitioning architecture enable designers to build truly reliable space-based systems wherein any part of the software, including application programs, RTOS middleware, and even the kernel and interrupt service routines, can be patched, replaced, or upgraded. "This kind of flexibility is a requirement in space due to the harsh environment and likelihood of an SEU (Single Event Upset) that can cause portions of memory to fail. Mission controllers can take advantage of INTEGRITY's field upgrade capabilities to work around hardware problems and extend the life and value of their space-based investments," commented David Kleidermacher, Vice President of Engineering at Green Hills Software. PJFS Green Hills Software's Partitioning Journaling File System (PJFS) is a natural partner with INTEGRITY for space-based systems and is also now available for the RAD750 space computer. PJFS employs complete file data and metadata journaling, ensuring that the file system and file data cannot be lost in the event of unexpected power loss. In addition, PJFS employs a patent-pending partitioning architecture that enables applications to have guaranteed media resources and access control, preventing unintended resource exhaustion or other failures that can arise when sharing a traditional file system with complex software. Finally, like INTEGRITY, PJFS sports a very small footprint that is ideal for resource-constrained systems. About the RAD750(TM) The RAD750 from BAE Systems is the most technologically advanced microprocessor ever offered to the space community. The RAD750 is a licensed radiation hardened version of the IBM PowerPC 750(TM). The RAD750 is a 3rd generation microprocessor, with almost ten times the performance of current space processors, and is the follow-on to BAE System's highly successful and space proven RAD6000(TM) family. The RAD750 is available in a single board computer in the CompactPCI(R) form factor. The RAD750 architecture supports an industry leading performance of 260 MIPS (Million Instructions Per Second) The execution speed of a computer.
