Abstract
An improved operating system and architecture, particularly useful for aircraft, provides a schedule for multiple tasks that ensures that each task has sufficient execution time and does not interfere with any other tasks. In the operating system, each task is scheduled to a deadline monotonic algorithm. The algorithm creates a schedule for the tasks in which the tasks are time partitioned by task, not by task level. The APIs in the operating system are provided by the services. Thus, changing a service, e.g. because of a change in hardware, is facilitated, since the service will provide the proper API.
