Green Hills Software's INTEGRITY® Selected As Operating System For F-35 Joint Strike Fighter

Santa Barbara, CA, October 31, 2001 -- Green Hills Software, Inc., today announced that Lockheed Martin will be using Green Hills' INTEGRITY® real-time operating system (RTOS) and AdaMULTI® 2000 software development tools to develop software for its Joint Strike Fighter (JSF) aircraft. Lockheed Martin's design for the JSF was selected by the Department of Defense (DoD) in a $200 billion award, the largest in US DoD history. Avionics software developed by Lockheed Martin will run on airborne PowerPC processors operating under the INTEGRITY RTOS.

"We're proud to be part of the Lockheed Martin JSF team," said John Carbone, vice president of marketing at Green Hills. "Lockheed Martin's selection demonstrates INTEGRITY's ability to meet the demanding security and safety-critical software requirements of the Joint Strike Fighter. This design win demonstrates our commitment to the airborne computer marketplace."

Carbone continues, "The INTEGRITY RTOS, together with Green Hills' AdaMULTI IDE, and Ada 95/C/C++ compilers provides a complete single-vendor RTOS and development solution for developing real-time mission and safety-critical software systems capable of meeting the security and safety standards of ISO/IEC 15408 (Common Criteria) and RTCA DO-178B. No other RTOS provides a more secure, memory-protected run-time system capable of meeting the security and safety requirements of today's advanced avionics and flight control systems."

John Ledyard, software manager at Lockheed Martin adds, "INTEGRITY is an outstanding product that we are very excited about. Green Hills involved us early in product definition and as a result INTEGRITY meets our needs. An embedded RTOS with virtual memory support and the capability to meet security standards was a key enabler in the design of our mission critical software. In the past, we would have to develop a custom RTOS and modify development tools at a significant cost. With INTEGRITY, and its tight integration with the excellent AdaMULTI software development tools, we are able to focus our efforts on our strengths which are in application software development and integration. This will result in reduced cost and risk for us and our customers."

INTEGRITY RTOS is optimized for safety-critical embedded applications that place a premium on maximum reliability, security, and testability. It features advanced memory protection capabilities, an optional ARINC-653 partition scheduler, dynamic download, task- and system-level debug, a configurable real-time EventAnalyzer, POSIX support, and TCP/IP networking. It is also the first memory-protected real-time operating system to be offered on a royalty-free basis.

INTEGRITY is engineered from the ground up to provide security and determinism. At the lowest level, the kernel employs an object-oriented design and access verification to protect against inadvertent and malicious kernel access problems such as invalid kernel addresses and invalid system call parameters. The kernel design also guarantees bounded computation times by eliminating the need for features such as dynamic memory allocation and heuristic scheduling. Underlying hardware mechanisms are used to provide full system memory protection of all components, including user applications, device drivers, and inter-address space communications. Clocks and timers are protected with access permissions and implemented entirely in software.

INTEGRITY is tightly integrated with Green Hills' AdaMULTI® IDE. Together with Green Hills' family of optimizing Ada 95, C, and C++ compilers, AdaMULTI automates all aspects of embedded software development, including editing, source-level debugging, program building, run-time error checking, version control, and code/performance optimization. INTEGRITY also features ISIM, an RTOS simulator that enables programmers to develop and test their code on a PC or workstation without the need for target hardware. INTEGRITY also includes the EventAnalyzer™, which enables viewing of system and user events in a graphical display.

Lockheed Martin is headquartered in Bethesda, Md., and is a global enterprise principally engaged in the research, design, development, manufacture and integration of advanced-technology systems, products and services. The corporation's core businesses are systems integration, space, aeronautics and technology services.
