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.
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
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
