Abstract
Techniques described herein generally relate to multi-core processors including two or more processor cores. Example embodiments may set forth devices, methods, and computer programs related to calculating a clock rate for one or more of the processor cores in the multi-core processor. One example method may include determining a first estimated workload for a first processor core and a second estimated workload for a second processor core within a scheduling interval in a periodic scheduling environment. In addition, a first clock rate for the first processor core may be calculated based on one or more of the first estimated workload, a maximum clock rate supported by the multi-core processor and/or the scheduling interval. Similarly, a second clock rate for the second processor core may also be calculated based on one or more of the second estimated workload, the maximum clock rate, and/or the scheduling interval.
