Abstract: A computing device includes a multi-core processor which includes two or more cores, each having a significant task list queue and a normal task list queue, and a scheduler which allocates a task to each of the two or more cores. The scheduler, following allocation of the tasks, receives a new task, selects one core among the two or more cores based on task information of the new task, and allocates the new task to the selected core, when the allocation of the new task to the selected core will not change an execution schedule of a significant task in the significant task list queue of the selected core.

Abstract: A computing device and a method for operating the computing device are provided. The computing device includes a task classifying module and a task allocating and managing module. The task classifying module classifies a task scheduled to be processed by a multi-core processor into an expectable task or a normal task. The task allocating and managing module selects one core of the multi-core processor as a target core and allocates the task scheduled to be processed to the target core. In response to the task scheduled to be processed being classified as the normal task, the task allocating and managing module determines whether to allocate the normal task to the target core depending on whether the target core processes a previously allocated expectable task.
