ABSTRACT:
The invention provides a method and apparatus for embedding a real-time multi-tasking kernel in a non-real-time operating system. Through encapsulating a real-time kernel into the interrupt handling environment of a non-real-time graphical user interface, such as Windows.RTM., the method of the present invention allows for an entire real-time environment to be supported within the graphical user interface. The scheduler of the real-time kernel supports multiple threads of execution all running at higher priority than the graphical user interface tasks. By using synchronization mechanisms of the graphical user interface, e.g. V.times.D events in enhanced mode Windows.RTM., the real-time tasks are able to make use of system services of the graphical user interface.
