M‑RTOS: A Trusted Multicore Architecture for Safety‑Critical and AI‑Driven Systems By Brandon Bhatnagar, Senior Technical Project Manager / M-RTOS Product Manager, MANNARINO Systems & Software Inc. For more than two decades, MANNARINO Scalian Group has delivered internationally recognized expertise in aerospace engineering of safety critical systems, certifiable software, and electronic hardware for demanding operational environments. Trusted across aerospace and defense programs, MANNARINO focuses on technologies that deliver predictability, system assurance, and long term deployability. The latest evolution of the MANNARINO Real Time Operating System, M-RTOS, reflects this focus and provides a more capable RTOS foundation than conventional solutions used in modern military platforms. M-RTOS is purpose built for multicore microprocessors and offers strong time and space partitioning based on ARINC 653, with an architecture suitable for certification to the highest industry and defense standards. Unlike RTOS products that primarily address task scheduling, M-RTOS is engineered to manage interference across shared hardware resources in complex System on Chip environments. Integrated interference mitigation mechanisms ensure strong isolation between cores and shared resources, and embedded Safety Net monitors detect and report unmitigated or unexpected interference, providing greater operational insight and resilience. While each system necessitates the use of a customized set of interference mitigation techniques, MANNARINO has established reliable approaches utilizing a combination of memory partitioning, bus bandwidth limitation and interrupt budgeting. Through memory partitioning, M-RTOS bounds shared cache and DRAM interference, addressing a common limitation in multicore RTOS implementations. By isolating shared memory components, M-RTOS improves the predictability of partitions running across cores. These gains are particularly significant for interference sensitive applications, enabling more reliable execution of mixed criticality workloads such as avionics, sensors, communications, and mission computing. M-RTOS further differentiates itself through built in Qualityof-Service enforcement using per partition bus budgeting. System integrators can configure the maximum number of bus accesses permitted during a time window, ensuring deterministic performance under peak operational loads. Many RTOS solutions offer limited visibility or control over shared bus contention, while M-RTOS enables precise, system level resource
management. Bounded interrupt servicing adds an additional layer of control by allowing configurable limits per interrupt source, reducing latency variability and protecting time critical functions. As systems increasingly incorporate artificial intelligence, autonomy, and software defined capabilities, security and observability become integral to mission success. M-RTOS can provide a strong foundation by supporting real time collection of both application level and RTOS internal events. These events can be timestamped, normalized, and prepared for analysis, enabling advanced situational awareness. Artificial intelligence models can be trained using such event data to identify meaningful event sequences that signal elevated security risks. When threats are detected, preconfigured security policies can be enacted, including privilege restriction, partition management, or trusted boot reinitialization, helping systems maintain integrity and mission readiness. This capability is supported by deep domain leadership. Brandon Bhatnagar brings more than 20 years of experience in embedded RTOS technologies, with a focus on multicore architectures, hypervisors, and aerospace software certification. He holds degrees in Medical Biophysics and Management in Artificial Intelligence and applies AI and machine learning to real time, mission critical systems.
