Green Hills Software, Inc., a major company in embedded software development tools and real time operating systems (RTOS), recently announced that its INTEGRITY RTOS and AdaMULTI integrated development environment (IDE) are being used in the development and implementation of mission-critical systems deployed in the latest Eurofighter Typhoon aircraft. The INTEGRITY RTOS is being incorporated as a critical component in a number of the aircraft’s “line- replaceable” items.

David Smith, Software Manager, of Eurofighter GmbH, the consortium managing Eurofighter’s development and production, said, “The INTEGRITY RTOS is an essential element in delivering the levels of system availability and reliability that are required by a number of computers being developed for Eurofighter Typhoon”.

“We are confident that the decision to use Green Hills Software’s RTOS and tools will contribute to the success of the second stage of the Eurofighter program”, commented Jon Williams, European Director of Safety Critical Business for Green Hills Software. “This evolution, which includes a move to PowerPC devices, greatly benefits from the use of the INTEGRITY RTOS, which maximizes security and reliability and leverages the hardware memory protection facilities of the PowerPC processor. In addition, the AdaMULTI IDE provides an intuitive tool for testing during both software design and production”.

The royalty-free INTEGRITY RTOS is a scalable, ROMable, and memory- protected RTOS. Leveraging the hardware memory protection facilities of the PowerPC processor’s memory management unit (MMU), the INTEGRITY RTOS maximizes security and reliability by building a firewall between the kernel and user tasks. This prevents errant or malicious tasks from corrupting user data, the kernel, interprocess communications, device drivers, and other user tasks. In addition, the INTEGRITY RTOS guarantees the availability of system resources like the CPU and memory to application processes, making it far more secure and deterministic than conventional embedded operating systems.

The AdaMULTI IDE is a complete, integrated set of tools for the development of embedded applications using Ada 95, C, C++, Embedded C++, and Fortran. The AdaMULTI IDE runs on Windows, Linux, and UNDC hosts and supports cross- debugging to a variety of target environments. The AdaMULTI IDE contains all of the tools needed to debug and deploy major programming project including: source level debugger, project builder, event analyzer, performance profiler, run-time error checker, and non-intrusive field debugging.
