Lockheed Martin Selects Green Hills Software's INTEGRITY Real-Time Operating System for Joint Strike Fighter EMD Aircraft.

Business Editors

SANTA BARBARA, Calif.--(BUSINESS WIRE)--April 7, 2000

Green Hills Software Inc., today announced that Lockheed Martin has selected its INTEGRITY(TM) 2000 Real-Time Operating System (RTOS) and AdaMULTI(R) software development tools to develop Ada 95 and C/C++ software for Mission Systems in its Joint Strike Fighter (JSF) EMD aircraft.

Avionics software developed by Lockheed Martin using AdaMULTI will run on airborne PowerPC processors operating under the INTEGRITY RTOS.

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

Carbone continued, "The AdaMULTI IDE, together with Green Hills' Ada 95/C/C++ compilers and INTEGRITY RTOS, provides a complete single-vendor development and RTOS 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 commercial compiler and 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 the application software development and integration. This will result in reduced cost and risk for us and our customers."

The INTEGRITY RTOS, tightly integrated with Green Hills' AdaMULTI software development environment, is optimized for mission-critical embedded applications that place a premium on high reliability, security, and testability. INTEGRITY features advanced memory protection capabilities, dynamic download, task- and system-level debug, a configurable real-time Event Analyzer, 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's modern, secure design guarantees full protection in both the time and space domains. Its memory-protection and error-handling features provide a secure system with built-in fault isolation and tolerance. And its unique approach to resource management, which encompasses processor utilization and memory management, provides guaranteed resource availability for multiple mission-critical or safety-critical applications on a single processor operating at different security or safety levels.

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.

The AdaMULTI software development environment automates all aspects of Ada 95 and C/C++ software development. Fully integrated with INTEGRITY, AdaMULTI features Ada 95 and C/C++ compilers, a source-level symbolic debugger, and an automated program builder. AdaMULTI also provides a version control system, an Event Analyzer, a code performance and coverage profiler, a source code navigation and cross reference browser, language sensitive editor, dependency and call graph displays and unit test tools.

Lockheed Martin received one of two JSF Concept Demonstration contracts awarded by the Department of Defense in November 1996. Flight evaluation of the demonstrator aircraft is scheduled to take place in 2000, with government selection of a single contractor for the Engineering and Manufacturing Development phase set for 2001.

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.
