Abstract: Example methods and terminals, including a CPU and an auxiliary processor, are disclosed. One example method includes, in a switch-on process of the terminal and after completing system initialization, determining, by the auxiliary processor, a minimum working voltage of the CPU. The auxiliary processor can then set a current voltage of the CPU to the minimum working voltage. The CPU, at the minimum working voltage, can then complete the switch-on process of the terminal and control the terminal to work.

Abstract: The invention provides a load monitor. The load monitor is configured to monitor a load status of a core, and control, according to the load status of the core, a low dropout regulator LDO to output a voltage to the core. The load monitor includes a control module and a monitoring module. A monitoring end of the monitoring module is connected to a signal output end of the core. An output end of the monitoring module is connected to an input end of the control module. A control end of the control module is connected to an input end of the monitoring module. An output end of the control module is connected to a control end of the LDO. An output end of the LDO is connected to a voltage input end of the core. The control module is configured to control the monitoring module to operate or power off.
