RTX Real-Time Operating System
Today, microcontroller applications often require simultaneous
execution of multiple tasks in a real-time environment.

without using a real-time kernel, the proven Keil RTX allows
you to focus on application development, enabling you to save

RTX is a royalty-free, real-time operating system specifically
developed for the ARM and Cortex-M feature-sets. RTX
provides features to manage system resources:

RTOS Aware Debugging
RTX is fully integrated in the μV ision Debugger making it easy
to monitor task status and kernel activity.
The RTOS-aware dialog is available in simulation and also

all aspects of the kernel and the running tasks. This enables you
to view statistics about the active tasks, stack loading, and
system resource usage.
