    Abstract: A scheduling method of a system on chip including a multi-core processor includes receiving a schedule-requested task, converting a priority assigned to the schedule-requested task into a linear priority weight, selecting a plurality of candidate cores, to which the schedule-requested task will be assigned, from among cores of the multi-core processor, calculating a preemption compare index indicating a current load state of each of the plurality of candidate cores, comparing the linear priority weight with the preemption compare index of the each of the plurality of candidate cores to generate a comparison result, and assigning the schedule-requested task to one candidate core of the plurality of candidate cores depending on the comparison result.

    Abstract: A system-on-chip includes a symmetric multi-processor including a plurality of cores, each configured to operate in a high performance operating mode and a low performance operating mode. The system-on-chip further includes a clock management unit configured to provide an operating clock signal to the symmetric multi-processor, a state management unit configured to monitor operating states of the cores, a temperature management unit configured to monitor a temperature of the symmetric multi-processor, and a symmetric multi-processor control unit configured to determine the operating clock signal and the operating states of the cores based on a workload of the symmetric multi-processor. The symmetric multi-processor control unit is further configured to differentially determine a maximum operating clock frequency for the cores based on the temperature and the operating states of the cores, which indicate a quantity of cores that are currently in operation.
