A soft real-time task scheduling method and the storage media thereof

摘要

PURPOSE: A soft real time task scheduling method and a recording medium thereof are provided to maintain a service quality more than a predetermined level in an application program wanted by a user although a some overload is carried in a system. CONSTITUTION: An application program(110) reserves an occupancy amount of a processor as to an application task through a processor occupancy amount setting module(120), desirably, a predetermined negotiation process, and supplies period characteristic information of the application task. The processor occupancy amount setting module(120) supplies a reserved processor occupancy amount and period characteristic information as to the application task to a scheduling module(140). The scheduling module(140) refers to the information and executes a scheduling as to the application program(110). A state sensing module(130) monitors a state of the application program(110) and reports contents thereof to the scheduling module(140) for optimizing a performance of a scheduling operation.
