Green Hills Software's INTEGRITY-178 tuMP Multicore Operating System Integrated into the Resilient Embedded GPS/Internal Navigation System Prototype Pilot

Infinite Dimensions Integration Selects Proven Leader in DO-178B Level A and EAL 6+ Operating Systems for an Airborne Demonstrator of the FACE Basic Avionics Lightweight Source Archetype Framework

---

SANTA BARBARA, CA — October 17, 2017— Green Hills Software, the worldwide leader in high assurance operating systems, today announced that it has been selected by Infinite Dimensions Integration to provide its INTEGRITY®-178 tuMP™ multicore operating system for the Resilient Embedded GPS/Internal Navigation System Prototype Pilot (R-EGI). Infinite Dimensions' R-EGI prototype is based on the Raspberry Pi3 platform, which incorporates a quad-core Cortex®-A53 ARMv8 SoC from Broadcom.

The R-EGI project is currently led by the Air Force Life Cycle Management Center and the Air Force Research Lab. R-EGI serves as an example for demonstrating the strategic change in avionics systems development using the Future Airborne Capability Environment (FACE) open systems architecture. It also is intended to validate an acquisition process experiment employing a community-based "Plug Fest/Plug Test" approach to rapidly explore the design space surrounding navigation systems architecture.

The Air Force R-EGI team of Infinite Dimensions and Green Hills Software rapidly prototyped an end-to-end vehicle control, navigation and guidance system (for air and ground) using the US Government's Basic Avionics Lightweight Source Archetype framework (BALSA) and the Green Hills INTEGRITY-178 tuMP operating system. The resulting software runs on a commercially available Raspberry Pi3 embedded computing platform, yet is portable to other ARMv8 parts or even Intel and PowerPC multicore architectures. The demonstration aircraft is a Piper Cub scale model that is electromechanically the same as a full size Piper aircraft. The resulting R-EGI software from Infinite Dimensions is portable to other "real" aircraft with reduced integration times.

"Infinite Dimensions' R-EGI demonstrator will prove a strategic transformation of both the acquisition process and a new approach to avionics system development that is agile, lowers the barrier to participation, simplifies accreditation (both cybersecurity and airworthiness), and reduces the timelines and resources required to build avionics systems and their components," said Dr. Jeffrey Wallace from Infinite Dimensions Integration.

"Green Hills Software is extremely honored that Infinite Dimensions has selected our INTEGRITY-178 tuMP RTOS for their R-EGI demonstration project. Green Hills Software has a long and proud history of supplying our RTCA/DO-178B Level A compliant INTEGRITY-178 product line to several different GPS/Inertial Navigation System suppliers over the years," said Dan O'Dowd, founder and chief executive officer of Green Hills Software. "This R-EGI project allows our products and engineering services team to play a significant role in proving that Open Standards initiatives such as FACE can ultimately lower acquisition costs and streamline development schedules for the US Government."

Green Hills Software has a long history as an innovative leader in enabling critical embedded system designers to fully utilize advanced microprocessor features such as those found on today's multicore SoCs. Beginning with Green Hills Software's pioneering efforts of robust partitioning for single-core processors, its list of accomplishments continues with certified operating systems for today's highly capable Intel, ARMv8 and PowerPC multicore SoCs. Green Hills Software's INTEGRITY-178 tuMP has been shipping to aerospace and defense customers since 2010 and builds upon a proven sixteen-year service history and certification pedigree of its INTEGRITY-178 single-core predecessor by incorporating multicore operating system capabilities, including support for both DAL-A compliant AMP and SMP operation. The INTEGRITY-178 tuMP multicore operating system is available for Intel, ARM and NXP PowerPC/QorIQ architectures, supporting both 32-bit and full 64-bit operation. INTEGRITY-178 tuMP for Intel architectures also offers support for Linux, Windows and Android GuestOS virtualization. INTEGRITY-178 tuMP offers complete support for the ARINC-653 Part 1 Supplement 4 standard (including section 2 defining multicore operation), as well as Part 2's optional features such as Sampling Port Data Structures, Sampling Port Extensions, Memory Blocks, Multiple Module Schedules and File System. INTEGRITY-178 tuMP has other optional components which include a DAL-A compliant network stack with multicast support and a 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. The INTEGRITY-178 tuMP operating system uniquely provides the ability to integrate a multicore processor into a safety-critical system while achieving optimal use of all cores in a deterministic manner that complies with RTCA/DO-178B DAL-A and the FAA's CAST-32A position paper for multicore processors.
