RTX can be configured to use Round-Robin Multitasking (or task switching). Round-Robin allows quasi-parallel execution of several tasks. Tasks are not really executed concurrently but are time-sliced (the available CPU time is divided into time slices and RTX assigns a time slice to each task). Since the time slice is short (only a few milliseconds) it appears as though tasks execute simultaneously. Tasks execute for the duration of their time-slice (unless the task's time slice is given up). Then, RTX switches to the next task that is ready to run and has the same priority. If no other task with the same priority is ready to run, the currently running task resumes it execution. The duration of a time slice can be defined in the RTX_config.c configuration file. The following example shows a simple RTX program that uses Round-Robin Multitasking. The two tasks in this program are counter loops. RTX starts executing task 1, which is the function named job1. This function creates another t
