Rockwell Collins Selects Green Hills Software's INTEGRITY®-178B RTOS To Fly In New Sikorsky S-92 Helicopter


Santa Barbara, CA. August 1, 2002 -- Green Hills Software today announced that Rockwell Collins has integrated the INTEGRITY®-178B real-time operating system (RTOS) into the Sikorsky S-92 helicopter's new highly-integrated avionics package. INTEGRITY-178B, along with Green Hills Software's GSTART Ada run-time environment, is being used in Rockwell Collins new Avionics Management and Display System, which incorporates the most advanced avionics technology available today for rotorcraft. Rockwell Collins successfully completed its first S-92 test flight of the system on October 5, 2001 and has accumulated over 300 hours of company flight tests to date. The new S-92 cockpit is designed for outstanding visibility and is equipped with a highly-integrated avionics package which provides the core of an open architecture avionics suite for processing aircraft system information. Flight data is shown on four Collins multi-function displays, with a fifth display offered as an option.

Green Hills also announced that Rockwell Collins is using Green Hills Software's AdaMULTI® Integrated Development Environment (IDE) to develop the flight software for the new S-92 cockpit.

Rockwell's S-92 cockpit The S-92 is Sikorsky's newest medium-lift helicopter and is designed to meet both civil and military requirements. Featuring a passenger capacity of 19-22, the versatile new helicopter will serve a variety of commercial and international utility needs, including passenger, cargo, aeromedical, search and rescue and resource development support.

A Motorola PowerPC running INTEGRITY-178B and the GSTART Ada run-time environment provides the backbone for the Sikorsky helicopter's new Collins Avionics Management and Display system. The system provides the display and integrated management of primary flight data, presentation and management of navigation information for the S-92. The system also provides flight management data, a digital map, weather radar, terrain information and engine instrument caution and advisory system processing and display. Rockwell Collins will use INTEGRITY-178B and GSTART to achieve DO-178B Level A certification of the Avionics Management and Display system.

"INTEGRITY-178B is the RTOS of choice for safety-critical applications like the S-92 helicopter, where the overwhelming emphasis is on safety, security and high integrity software development," said John Carbone, vice president of marketing for Green Hills Software. "INTEGRITY-178B's robustly partitioned architecture, real-time deterministic performance, and overall ease-of-use of the AdaMULTI tool chain gives it a clear advantage over general purpose RTOSes like VxWorks."

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. This partitioning effectively builds a firewall between applications and the kernel, preventing errors in one application from corrupting other applications or the kernel. INTEGRITY-178B also provides protection and guaranteed resource availability in both the time and space domains, thereby enabling applications that have been assigned different DO-178B safety levels to run concurrently on the same processor (i.e. supports "robust partitioning," as defined in ARINC-653. INTEGRITY-178B's ARINC-653 APplication/EXecutive (APEX) interface provides a recognized standard interface between the operating system of an avionics computer resource (ACR) and the application software.

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 (EventAnalyzer™) that enables viewing of system and user events in a graphical display.

INTEGRITY-178B is tightly integrated with Green Hills Software's AdaMULTI® 2000 IDE. Together with the 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. AdaMULTI also features an advanced code coverage tool (GCOVER™) 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).
