Abstract
A task management system that inherit priority and that can reduce the queue operation required for transition to/return from a mutual exclusion awaiting state The task management system can execute a task without considering its priority, start or stop a server task and inherit priority without operating the dispatch queue. The task management system includes activity retaining information, context retaining information, and a dispatch queue used to select the highest priority task. Information on a task is divided and managed by the activity and the context, where each activity is inserted into/deleted from the dispatch queue. When the priority of a task is inherited by another task, only the correspondence between activity and context is changed.
