Business Editors/High-Tech Writers

SANTA BARBARA Santa Barbara (săn'tə bär`brə, –bərə), city (1990 pop. 85,571), seat of Santa Barbara co., S Calif., on the Pacific Ocean; inc. 1850. , Calif.--(BUSINESS WIRE)--Sept. 30, 2002

Green Hills Software Inc. today announced that Ryan International Corp., a leading provider of business and general aviation avionics systems, has selected Green Hills Software's INTEGRITY-178B(TM) real-time operating system (operating system) Real-Time Operating System - (RTOS) Any operating system where interrupts are guaranteed to be handled within a certain specified maximum time, thereby making it suitable for control of hardware in embedded systems and other time-critical applications.  (RTOS (1) (RealTime Operating System) An operating system designed for use in a real time computer system. See real time system, embedded system, process control and OS-9. ) for its avionics product development.

Ryan International will use INTEGRITY-178B to help achieve DO-178B certification for all of its industry-leading aviation hazard detection and warning systems, beginning with the Multi-Function Display (MFD (MultiFunction Device) Hardware that combines several functions in one unit. See all-in-one. ) flight safety system.

"INTEGRITY-178B provides an excellent safety-critical RTOS platform, and is the only RTOS that gives us a clear path to DO-178B certification," said Dean Ryan, vice president of engineering with Ryan International Corp. "INTEGRITY-178B partitions high level safety applications from those at lower levels, speeding the development and certification process."

Ryan International Corp.'s flagship product A primary product of a company, which is typically why the company was founded and/or what made it well known. For example, MS-DOS, Windows and the Microsoft Office suite have been flagship products of Microsoft.

(TM)), is an electronic transponder-based system that alerts pilots to potential collision threats within a traffic area. The MFD uses data received from the TCAD and other sources to generate a visual display of safety hazards outside the host aircraft, such as planes that are too close, or inclement in·clem·ent

INTEGRITY-178B is an ARINC-653 compliant, hard real-time operating system optimized for safety- and mission-critical applications that require FAA DO-178B certification, the utmost in security, and fast, predictable response. Featuring a complete DO-178B Level A Certification Package that shortens the time required to obtain DO-178B certification, INTEGRITY-178B provides real-time response, memory-protected partitions and guaranteed resource availability for both CPU time The amount of time it takes for the CPU to execute a set of instructions and generally excludes the waiting time for input and output.

 and memory. INTEGRITY also provides an optional ARINC-653 compliant partition scheduler, making it the only RTOS that can support Multiple Levels of Security (MLS See multilevel security. ) on a single processor.

Ryan is also using Green Hills Software's MULTI MULTI Multiple (R) Integrated Development Environment See IDE.

8245 processor. Ryan also plans to use MULTI and INTEGRITY-178B to develop and deploy embedded software for future avionics products that utilize the same MPC8245 platform.

"Leading military/aerospace systems companies like Ryan International are using INTEGRITY-178B to enhance the reliability of their systems and achieve DO-178B certification," said John Carbone, vice president of marketing for Green Hills Software Inc. "INTEGRITY-178B's partitioned architecture and guaranteed resource availability greatly simplify the development, deployment, and certification of safety-critical military and aerospace systems. We are pleased that Ryan International has selected INTEGRITY as the standard platform for its aviation safety products."

INTEGRITY-178B utilizes hardware memory protection and an advanced two-level partition scheduler to provide 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 ARINC Aeronautical Radio, Inc.

 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 See riser card. ) and the application software.

INTEGRITY-178B includes an RTOS simulator (ISIM ISIM IMS (IP Multimedia Subsystem) Subscriber Identity Module
ISIM Institute for the Study of International Migration
ISIM Integrated Science Instrument Module (James Webb Space Telescope) 
) 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 EventAnalyzer(TM) that enables viewing of system and user events in a graphical display.

INTEGRITY-178B is tightly integrated with Green Hills Software's MULTI(R) 2000 IDE. Together with Green Hills Software's family of optimizing Ada 95, C, and C++ compilers, MULTI automates all aspects of embedded software development, including editing, source-level debugging, program building, run-time error checking, version control, and code/performance optimization. MULTI also features an advanced code coverage tool (GCOVER(TM)) that automates structural coverage analysis for application software, including the analysis of DO-178B.
