Static means that all system objects are defined before compilation. This will result in optimized memory and timing requirements. System objects definition is easily performed by use of the comfortable configuration tool from Vector Informatik. Defined as highly scalable operating system, unused features may be switched off. There are multiple, powerful mechanisms to synchronize Tasks Events are predefined signals which start or wake up tasks on occurrence of asynchronous external or internal triggers.
Alarms are a means to implement timing sequences.
Resources is a means to synchronize the access to shared hardware or data. Dynamic priority switching prevents deadlocks or priority inversion. Task switching is performed with task activation or termination. Each task may be configured preemptive or non-preemptive behavior. These program entry points will be addressed whenever the operating system performs a specific task.
