  RTX Real-Time Operating System  
 

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.
 

 
 

Features

 
 
    Royalty-free, deterministic RTOS with source code Flexible Scheduling: round-robin, pre-emptive, and collaborative 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 Kernel aware debug support in MDK-ARM Dialog-based setup using µVision Configuration Wizard

 
 

Benefits

 
 

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.
