Abstract: A semiconductor device is provided. The semiconductor device includes a processing device that provides resource usage information including a utilization value; and a prediction information generating device that generates resource usage prediction information based on the resource usage information and provides the resource usage prediction information to the processing device. The prediction information generating device includes: an error calculator to calculate an error value between the utilization value and a predicted value included in the resource usage prediction information; a margin value calculator to receive the error value from the error calculator and calculate a margin value using the error value; an anchor value calculator to calculate an anchor value using the utilization value; and a predictor to output the predicted value using the anchor value and the margin value. The processing device controls resource allocation of the processing device based on the resource usage prediction information.

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: Provided are multi-core control systems. A multi-core control system includes multiple cores including a first core; and a process dependency recognizer configured to recognize a dependency between processes each executed in the respective cores, wherein if the first core waits for a first period of time to execute a first process, the first core recognizes a process on which the first process depends by the process dependency recognizer.
