Compare INTEGRITY RTOS vs. RTX

INTEGRITY employs hardware memory protection to effectively isolate and safeguard embedded applications. By utilizing secure partitions, it ensures that every task has the necessary resources to operate correctly while simultaneously shielding the operating system and user tasks from erroneous and harmful code, which encompasses threats like denial-of-service attacks, worms, and Trojan horses. To facilitate developers in expediting their product creation, Green Hills Software provides a comprehensive suite of middleware that has been integrated and validated for use with INTEGRITY, featuring options like FFS, FAT, NFS, and journaling file systems, alongside both IPv4 and IPv6 host and routing networking stacks, as well as a FIPS 140-2 certified Suite B embedded encryption library, among other tools. Notably, each middleware package has undergone pre-integration and rigorous testing to ensure it operates smoothly with INTEGRITY’s sophisticated RTOS features. Furthermore, Green Hills Software also presents tailored platforms for various industries, which encompass a fully integrated ecosystem that includes the INTEGRITY RTOS along with essential development tools, aiming to streamline the development process even further. This cohesive approach not only boosts efficiency but also enhances the overall security of embedded applications.

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.
