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

The Keil RTX is a deterministic, royalty-free real-time operating system tailored for ARM and Cortex-M devices, enabling the development of applications that can handle multiple tasks concurrently, resulting in more organized and maintainable code. This RTOS comes with source code, allowing for greater flexibility in programming. While it is feasible to implement real-time applications without an RTOS by using a Super-loop to run one or more functions, doing so can lead to various challenges related to scheduling, maintenance, and timing, all of which are efficiently managed by the Keil RTX. For those interested in understanding the benefits of an RTOS compared to a Super-loop approach, a detailed comparison highlights the advantages of adopting an RTOS. Additionally, Keil RTX offers high-speed real-time operations with minimal interrupt latency and a compact footprint suitable for resource-limited systems. It supports an unlimited number of tasks, each capable of having up to 254 levels of priority, as well as an infinite number of mailboxes, semaphores, mutexes, and timers, making it an ideal choice for applications requiring multithreading and thread-safe functionality. Overall, the Keil RTX provides developers with a powerful toolset for creating efficient and robust real-time applications.
