The Keil RTX is a royalty-free, deterministic Real-Time Operating System designed for [[:en:microcontrollers:arm|ARM]] and [[:en:microcontrollers:cortex-m|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((RTX Source code is included in all MDK-ARM Editions.))
  * 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 [[http://www.keil.com/arm/mdk.asp|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 [[http://www.keil.com/rl-arm/rtx_rtosadv.asp|advantages of using an RTOS]].
