Santa Barbara, CA. July 1, 2002 -- Green Hills Software, Inc., today announced that NLX Corporation is using the INTEGRITY® real-time operating system (RTOS) and AdaMULTI® Integrated Development Environment (IDE) to upgrade the B-1 Bomber Weapons System Trainer (WST). The WST is used to train aircrews for missions aboard the B-1 Bomber, providing pilots and weapons systems officers with a true to-life simulation of the B-1's flight and weapons systems.

The INTEGRITY RTOS, hosting PowerPC 740 application software developed with Green Hills Software's AdaMULTI® Integrated Development Environment (IDE), is used in the B-1's flight control system, which performs all the navigation, guidance, display, and weapons system functions. The WST duplicates the B-1 environment, from the design of the cockpit, to the PowerPC/INTEGRITY-based software used in the B-1's flight computers.

NLX selected INTEGRITY and AdaMULTI for the WST in order to create a precise simulation environment for the B-1. However, NLX engineers also cited INTEGRITY's flexible build environment, noting that INTEGRITY made it easy for them to add special training software to the WST. Unlike the software used in the actual B-1, NLX engineers had to custom-build code that "listens" for messages from the training instructor. This software, known as trainer hooks, allows instructors to stop the simulator mid-flight and give assistance to trainees.

"INTEGRITY not only provides an ideal run-time environment for hosting mission-critical flight control and weapons tasks aboard the B-1," said John Broman, a project engineer with NLX Corporation, "but it also gives us the flexibility we need to build a rich, customizable B-1 simulation and training environment."

"INTEGRITY has emerged as the RTOS of choice for safety- and mission-critical applications like military and commercial aircraft," said John Carbone, vice president of marketing for Green Hills Software. "INTEGRITY and MULTI provide the ideal environment for developing, hosting, and simulating mission-critical software for advanced aircraft like the B-1. We are pleased to have been selected by NLX for this prestigious project."

INTEGRITY is a secure, fast, deterministic, real-time operating system optimized for embedded applications that place a premium on safety, reliability, real-time performance, and testability. Utilizing a processor's memory management (MMU) facilities, INTEGRITY builds a firewall between the kernel and user tasks that prevents errant or malicious code from corrupting other user tasks or the kernel. INTEGRITY also delivers maximum responsiveness and determinism by running with interrupts continuously enabled and guaranteeing access to the CPU and memory for critical tasks.

INTEGRITY is tightly integrated with the AdaMULTI IDE, which, together with Green Hills Software's family of Ada95 and C/C++/EC++ optimizing compilers, automates all aspects of embedded PowerPC software development. AdaMULTI features an INTEGRITY-aware source-level debugger, graphical program builder, run-time error checker, version control system, and performance profiler. AdaMULTI also features an INTEGRITY simulator (ISIM), which enables programmers to develop and test their code on a PC or workstation without the need for target hardware, and a real-time event analyzer (EventAnalyzer™), which enables users to view system and user events in a graphical display.
