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.”


With support for both AMP and SMP operation, the INTEGRITY-178 tuMP multicore operating system is available for Intel, NXP PowerPC/QorIQ and ARM architectures, supporting both 32-bit and 64-bit operation. INTEGRITY-178 tuMP for Intel architectures also offers support for both Linux and Windows GuestOS virtualization. INTEGRITY-178 tuMP offers complete support for the ARINC-653 Part 1 standard as well as the Part 2 optional features such as Sampling Port Data Structures, Sampling Port Extensions, Memory Blocks, Multiple Module Schedules and File System. INTEGRITY-178 tuMP offers advanced options such as a DO-178B Level A compliant network stack and file system, both based on a Client/Server architecture that features the ability of the Level A Server to communicate simultaneously with multiple Clients operating at different safety levels (DAL A – E), located on the same or different cores. INTEGRITY-178 aligns with the FACE™ 2.1 Safety Base and Security profiles, with support for the current FACE 3.0 Safety Base and Security draft profiles already in place.
