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

 

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.
