摘要
An improved method and apparatus for embedding a real-time (34) multi-tasking kernel (26) in a non-real-time operating system is disclosed. Through encapsulating a real-time kernel into the interrupte handling environment of a non-real-time operating system, such as Windows3, the method of the present invention allows for an entire real-time environment to be supported within the operating system. The scheduler of the real-time kernel supports multiple threads of execution all running at higher priority than the application tasks. By using synchronization mechanisms of the operating system, e.g. V x D events in enhanced mode Windows3 (figure 3), the real-time tasks are able to make use of system services of the operating system. Real-time tasks not requiring system services execute more quickly from interrupt mode. Real-time tasks (34) requiring system services execute partially from interrupt mode and partially from event mode (figure 9).
