RTX Real-Time Operating System

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.

• Royalty-free, deterministic RTOS with source code¹⁾
• 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

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.
