Description

Deos™, developed by DDC-I, is a safety-critical real-time operating system (RTOS) that has been rigorously verified according to DO-178C/ED-12C Design Assurance Level A (DAL A) standards specifically for avionics applications. This RTOS supports ARINC 653 APEX and rate monotonic scheduling (RMS), and it is designed to meet the FACE Safety Base Profile requirements. Since its initial verification by Transport Canada in 1998, it has been a trusted solution in the aviation industry, with its certification allowing it to operate in tens of thousands of aircraft. Over the past two decades, Deos has adapted and evolved to incorporate new processors and features, demonstrating its flexibility and resilience. It has also undergone successful audits by a range of global certification authorities, including the FAA, ENAC, JAA, EASA, and CAAC, as well as by designated engineering representatives from various airframe and avionics suppliers, ensuring its continued compliance with industry standards. Its proven track record and ongoing development make it a pivotal component in modern aviation safety systems.

Description

Ranging from basic embedded environmental sensors and LED wearables to advanced embedded controllers, smartwatches, and IoT wireless applications, this system incorporates configurable architecture-specific stack-overflow protection, kernel object and device driver permission tracking, and thread isolation enhanced by thread-level memory protection across x86, ARC, and ARM architectures, as well as userspace and memory domains. For systems lacking MMU/MPU and those limited by memory capacity, it enables the integration of application-specific code with a tailored kernel to form a monolithic image that can be loaded and run on the hardware of the system. In this setup, both the application and kernel code operate within a unified address space, facilitating efficient resource utilization and performance optimization. This design ensures that even resource-constrained environments can effectively leverage complex applications and functionalities.
