WHITE PAPER Evaluating Safety-Certifiable Computing For Tomorrow 's Avionics mrcy.com 5 by unauthorized individuals and compares critical launch environment elements against a known good source. Intel® Total Memory Encryption ensures data privacy by encrypting physical external memory. These security features are available on 11th Gen Intel® Core™ Processor (codename Tiger Lake). From a supply chain perspective, Intel processors are exclusively developed and fabricated by Intel but ARM does not manufacture their own chips, instead licensing the rights to partners. The nature of the ARM production model means processors may be fabricated at many sites around the world, increasing supply chain risks. Autonomous flight, with its combination of performance, SWaP, integrated graphics and safety certification challenges is better served by Intel processors for UAM applications. See the Urban Air Mobility sidebar for more details. Mercury is working closely with industry groups to shape and influence policy decisions that will evolve safety certification standards to address these new types of systems. The goal is to exploit AI/ML/DL while simultaneously meeting both safety and security assurance levels. Intel's integrated inference capabilities make them better suited for future AI applications, which is a challenge because the underlying algorithms are, by their very nature, non-deterministic. One part of Mercury 's approach is converting algorithms into segmented, deterministic and bounded models, from which the necessary safety artifacts can be produced. Demand for certified graphics is satisfied by a simplified path to efficient, high performance in the Intel family of processors. For example, the Intel® Atom X Processor 's integrated GPU meets next-generation requirements for both merging applications and supporting HD cockpit display. GPU integration means that a mission computer based on the Intel® Atom can drive sophisticated graphics while it executes flight control and communications applications. Intel's processor product line can scale up to support a range of evolving low- to high-performance applications over a long life cycle to deliver cost savings. Most deployed airborne systems use a sensor centric architecture with a processor dedicated to each function. This prolongs the use of obsolete computing as sensors upgrade every 20 years and processor technology sees a new generation every 3 years. By moving towards a processor centric architecture, DoD platform program managers FIELDING TECHNOLOGY 7X FASTER WITH CONVERGED ARCHITECTURE reduce cost, keep pace with new technology, reduce computing footprint, and simplify platform management. A common server architecture simplifies, promotes and facilitates processing refresh to enable end users to field technology at the speed of new commercial advancements.
