Abstract: A scheduling method, medium and apparatus are provided. In the scheduling method, medium and apparatus, it is possible to prevent the possibility that the order between the priorities of the tasks represented by the expired timers and the tasks requested by the interrupt is reversed while also not deteriorating the performance of a real time operating system (RTOS), even though the number of timers expired when the interrupt occurs or that are already expired before the interrupt occurs is large, by selecting a timer for representing a point of time corresponding to a point of time when an interrupt occurs from among one or more timers each of which representing a task, a point of time assigned to the tasks, and a priority assigned to the task and executing a task represented by the selected timer and one or more tasks requested by the interrupt in order of priority.

Abstract: A synchronization scheduling apparatus and method in a real-time multi-core system are described. The synchronization scheduling apparatus may include a plurality of cores, each having at least one wait queue, a storage unit to store information regarding a first core receiving a wake-up signal in a previous cycle among the plurality of cores, and a scheduling processor to schedule tasks stored in the at least one wait queue, based on the information regarding the first core.

Abstract: Provided is a computing system having a hierarchical memory structure. When a data structure is allocated with respect to a task processed in the computing system, the data structure is divided and a portion of the data structure is allocated to a high speed memory of the hierarchical memory structure and a remaining data structure is allocated to a low speed memory of the hierarchical memory.

Abstract: A central processing unit (CPU) and a real-time scheduling method applicable in the CPU are disclosed. The CPU may determine a first task set and a second task set from among assigned tasks, schedule the determined first task set in a single core to enable the task to be processed, and schedule the determined second task set in a multi-core to enable the task to be processed.
