Design win; Green Hills’ OS runs flight computer, completes certification

August 19, 2016 // By Graham Prophet
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.

Esterline CMC’s initial deployment of INTEGRITY-178 tuMP 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. (see here). 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. (link here).

 

“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. “Our goal was to achieve the ideal Size, Weight, and Power reduction (SWaP) from modern multicore parts while simultaneously harnessing as much of their available throughput as possible. We needed a supplier capable of meeting these SWaP and throughput goals without jeopardizing our safety certification requirements. After a very thorough and extensive trade study, Green Hills Software’s INTEGRITY-178 tuMP was the only RTOS that met all of these requirements.”

 

“INTEGRITY-178 was the world’s first commercial multi-safety level partitioned RTOS to successfully comply with the certification requirements of RTCA/DO-178B Level A back in 2002,” said Dan O’Dowd, founder and chief executive officer of Green Hills Software. “We introduced our multicore update, INTEGRITY-178 tuMP, to the aerospace and defence industry five years ago, delivering the most functionally advanced and capable operating system for safety- and security-critical systems that rely on multicore processors....we are now proud to announce the successful completion of all DO-178B Level A certification activities for our INTEGRITY-178 tuMP operating system for Esterline CMC’s next generation of avionics products.”
