Abstract: Embodiments of a power consumption control apparatus, a processor, and a power consumption control method are disclosed, directed to improving accuracy of power consumption regulation. The power consumption control apparatus includes a constant-frequency clock generator and a power consumption regulator. The power consumption regulator is connected to one or more processing units in a system-on-a-chip. The constant-frequency clock generator provides a constant-frequency clock signal for the power consumption regulator. The power consumption regulator obtains power consumption caused by the one or more processing units in a period of time, and regulates current power consumption of the one or more processing units based on the power consumption. Because historical power consumption can better reflect a real status of the processing unit, a regulation policy determined based on the historical power consumption can also better meet a current requirement of the processing unit, thereby helping improve accuracy of power consumption regulation.
