Green Hills Software Extends Safety-Critical Multicore RTOS to 11th Gen Intel Core i7
The only RTOS used in a Multicore Certification to DO-178C and CAST-32A now is available for the latest Intel Core Processor
SANTA BARBARA, Calif., June 8, 2022 /PRNewswire/ -- Green Hills Software announced today that it has extended its certified multicore support of the INTEGRITY®-178 tuMP safety-critical real-time operating system (RTOS) to the 11th Gen Intel® Core i7 processor (formerly Tiger Lake). INTEGRITY-178 tuMP is the only RTOS to be part of the certification of a multicore system to DO-178C and CAST-32A multicore requirements. Green Hills Software has extended INTEGRITY-178 tuMP RTOS' long-standing support for Intel processors to single board computers and systems with the latest Intel Core i7 processor, including the AMMP-304-01 mission computer from Mercury Systems.
The 11th Gen Intel Core i7 processor can deliver up to 40x better performance than traditional safety-certifiable processors when all four processor cores are active and used efficiently. Certification to RTCA/DO-178C airworthiness is very difficult for multicore processors due to the unpredictable behavior resulting from shared resource contention among processor cores. The requirements for addressing that multicore interference are specified in the CAST-32A multicore position paper. The INTEGRITY-178 tuMP RTOS is the only operating system to be part of a successful multicore certification to DO-178C and CAST-32A objectives. Avionics computers certified to DO-178C objectives using other operating systems have only one core active in a multicore processor, with the other cores typically held in reset.
"We are pleased to expand our collaboration with Green Hills Software through its support of our latest Gen 11 Core i7 CPU in safety-critical avionics," said Tony Franklin, GM Federal and Aerospace Group, Intel Corporation. "The high performance of our latest processor in safety-critical airborne systems can only be realized with an operating system that supports full multicore utilization in a certifiable way. Green Hills Software has a demonstrated track record of multicore certifications."
"Our SOSA aligned DAL-certifiable 3U OpenVPX AMMP mission computer leverages 11th Gen Intel Core i7 processors to accelerate avionics applications and deploy them faster," said Jay Abendroth, vice president, Mercury Mission. "Combined with the Green Hills INTEGRITY-178 tuMP RTOS, the mission computer enables customers to leverage the latest commercial multicore technology to ensure rapid and successful safety certification."
The INTEGRITY-178 tuMP high-assurance RTOS from Green Hills Software is the only RTOS that has actually been part of a multicore system certified to DO-178C airborne safety requirements. INTEGRITY-178 tuMP is a multicore RTOS with support for running a multi-threaded DAL A application across multiple processor cores in symmetric multi-processing (SMP) or bound multi-processing (BMP) configurations, as well as supporting the more basic asymmetric multi-processing (AMP). INTEGRITY-178 tuMP was the first RTOS to be certified conformant to the FACE Technical Standard, edition 3.0, and it is the only RTOS with multicore interference mitigation for all shared resources, enabling the system integrator to meet CAST-32A objectives. Multicore interference happens when more than one processor core attempts simultaneous access to a shared resource, such as system memory, I/O, or the on-chip interconnect. To further ease compliance to CAST-32A, Green Hills provides bandwidth allocation and monitoring (BAM) functionality in INTEGRITY-178 tuMP that ensures that critical applications get their allocated access to shared resources in order to meet their required deadlines, significantly lowering integration and certification risk. Together, the flexible multi-processing architecture and multicore interference mitigation enable a system integrator to maximize multicore processor performance while meeting safety and security requirements.
Founded in 1982, Green Hills Software is the worldwide leader in embedded safety and security. In 2008, the Green Hills INTEGRITY-178 RTOS was the first and only operating system to be certified by NIAP (National Information Assurance Partnership comprised of NSA & NIST) to EAL 6+, High Robustness, the highest level of security ever achieved for any software product. Our open architecture, integrated development solutions address deeply embedded, absolute security and high-reliability applications for the military/avionics, medical, industrial, automotive, networking, consumer and other markets that demand industry-certified solutions. Green Hills Software is headquartered in Santa Barbara, CA, with European headquarters in the United Kingdom. Visit Green Hills Software at www.ghs.com.
