Green Hills Software's INTEGRITY-178B RTOS To Fly In Boeing's C-17

11/6/2002 - Green Hills Software announced that Boeing has selected its INTEGRITY-178BTM real-time operating system (RTOS) for use in the USAF C-17 Globemaster III jet transport plane.

INTEGRITY-178B, along with Green Hills Software's GMART (Green Hills Minimal Ada Run-Time) and GSTART (Green Hills Safe-Tasking Ada Run-Time System), will host the C-17's navigation, mission planning, and display functions. Boeing is also using Green Hills Software's AdaMULTI® Integrated Development Environment (IDE) and G-Cover code coverage tools to develop DO-178B-compliant Ada and C application software for the C-17.

The C-17 is a versatile jet transport plane optimized for tactical airlifts, airdrops, and rapid strategic delivery of troops and cargo to main operating and forward bases. With a payload of 160,000 pounds, the C-17 can take off from a 7,600-foot airfield, fly 2,400 nautical miles, land on a small austere airfield in 3,000 feet or less, and be refueled in flight. This combination makes the C-17 ideal for long missions in rugged terrain, particularly when the take off and landing airfields are small or not well developed.

"Boeing is using Green Hills Software's INTEGRITY and AdaMULTI in the C-17's Avionics System," said Hafez Lorseyedi, Director of C-17 Systems and Software. "Green Hills has been very responsive to our needs, and has provided us with great support on this critical program."

"Green Hills Software has a long history working with Boeing on projects such as the C-17," said John Carbone, vice president of marketing for Green Hills Software. "INTEGRITY-178B and AdaMULTI are fast becoming the RTOS and IDE of choice for developing and deploying DO-178B-compliant software for safety-critical applications."

INTEGRITY-178B is an ARINC-653 compliant, hard real-time RTOS optimized for safety-critical and mission-critical applications that require the utmost security and fast, predictable response. Utilizing hardware memory protection and an advanced two-level partition scheduler, INTEGRITY-178B provides complete time, space, and resource partitioning between applications operating on the same hardware platform. INTEGRITY-178B also provides guaranteed resource availability in both the time and space domains. This combination facilitates "robust partitioning" (as defined in ARINC 653), enabling applications that have been assigned different DO-178B safety levels to run concurrently on the same processor.

INTEGRITY-178B includes an RTOS simulator (ISIM) that enables programmers to develop and test their code on a PC or workstation without the need for target hardware. INTEGRITY-178B also features a real-time event analyzer (EventAnalyzerTM) that enables viewing of system and user events in a graphical display.

INTEGRITY-178B is tightly integrated with Green Hills Software's AdaMULTI® IDE. Together with Green Hills Software's 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. AdaMULTI also features an advanced code coverage tool (GCOVERTM) that automates structural coverage analysis for application software, including the analysis of DO-178B Table A-7, Objectives 5, 6, and 7 (statement, decision, and MCDC coverage achievement).
