Green Hills certifies RTOS for avionics computers

Green Hills Software has announced that it has completed all of the RTCA/DO-178B Level A certification requirements for its Integrity-178 tuMP multicore real-time operating system (RTOS) for Esterline CMC's next generation of integrated avionics computers and smart displays.

By Richard Wilson - Electronics Weekly, Aug. 18, 2016 – 

Esterline CMC's initial deployment of the RTOS will be on its 3rd generation MFD-3068 Smart Display which uses an NXP P3041 multicore processor.

The MFD-3068 Smart Display will be deployed on the Antonov Airlines AN-124 transport aircraft and AN-148/AN-158/AN-178 regional jets which will be certified by Esterline CMC and Transport Canada Civil Aviation.

The MFD-3068 Smart Display has also been selected by Airbus Helicopters and the German Armed Forces for the upgrade of their CH-53GS/GE Sea Stallion helicopters.

"Today's multicore technology offered us the increased computing capacity that we required for our advanced line of smart displays and mission computers, but also presented serious safety challenges with their integration and deployment in flight critical systems as compared to the previous generation of single core processors," said Jim Palmer, Vice President Products and Navigation Solutions at Esterline CMC.
