System and method for performing multi-task processing

摘要

The present invention provides a technique for improving the processing efficiency of a processor in a multi-tasking processing system. A first scheduler generates an event processing unit by linking one or a plurality of events that are capable of being executed by the system under the same context. A second event scheduler performs processing of events that are included in the event processing unit created by the first event scheduler and processing that performs event switching not accompanied by context switching when processing of each event is terminated. A time-sharing system scheduler causes a processor to execute as tasks respectively the operation of the first and second event schedulers. The processing efficiency of the processor is improved by executing event switching not accompanied by context switching by the first and second event schedulers.
