Developers and enterprises seeking a real-time operating system designed to help in the development of embedded applications

About embOS

embOS is a priority-controlled RTOS (real-time operating system). It is designed to be the foundation for developing embedded applications and is continually developed since 1992. embOS is available for all popular cores, compilers and development tools and has been deployed in several billion devices in a range of application areas. Since 1992, embOS has been the preferred RTOS choice for engineers in the embedded market. It offers ease-of-use and guarantees 100% deterministic real-time operation for any embedded device. This real-time operating system is highly portable and fully source-compatible on all platforms, making it easy to port applications to different cores. Tasks can easily be created and safely communicate with each other, using communication mechanisms such as semaphores, mailboxes, and events. The real-time operating system is free for any non-commercial use like education and evaluation, without any technical limitation.

MQX RTOS

The MQX real-time operating system (RTOS) provides real-time performance within a small, configurable footprint. The RTOS is tightly integrated with 32-bit MCUs and MPUs from NXP and is provided with commonly used device drivers. The MQX RTOS is designed to have a modern, component-based microkernel architecture allowing for customization by feature, size, and speed by selecting the components engineers wish to include while meeting the tight memory constraints of embedded systems. The MQX RTOS can be configured to take as little as 8 KB of ROM and 2.5K RAM on Arm Cortex M4, including kernel, 2 task applications,1 LW Semaphore, interrupt stack, queues, and memory manager. Provides a fully-functional RTOS core with additional, optional services. Components are linked in only if needed, preventing unused functions from bloating the memory footprint. Key components are included in both full and lightweight versions for further control of size, RAM/ROM utilization and performance options.

RTX

The Keil RTX is a royalty-free, deterministic real-time operating system designed for ARM and Cortex-M devices. It allows you to create programs that simultaneously perform multiple functions and helps to create applications which are better structured and more easily maintained. Royalty-free, deterministic RTOS with source code. While it is certainly possible to create real-time programs without an RTOS (by executing one or more functions in a Super-loop), there are numerous scheduling, maintenance, and timing issues that an RTOS like the Keil RTX solves for you. For a more detailed comparison between RTOS and Super-loop, take a look at the advantages of using an RTOS. High-Speed real-time operation with low interrupt latency. Small footprint for resource constrained systems. Unlimited number of tasks each with 254 priority levels. Unlimited number of mailboxes, semaphores, mutex, and timers. Support for multithreading and thread-safe operation.
