Green Hills Software's INTEGRITY-178B real-time operating system (RTOS) is to be used in the Boeing USAF C-17 Globemaster III jet transport plane. The RTOS and the company'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' 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 jet transport plane optimised for tactical airlifts, airdrops, and rapid strategic delivery of troops and cargo to main operating and forward bases.
INTEGRITY-178B is an ARINC-653 compliant, hard real-time RTOS which provides complete time, space, and resource partitioning between applications operating on the same hardware platform. It includes an RTOS simulator (ISIM) that enables programmers to develop and test code on a PC or workstation without the need for target hardware.
