Power-on operation execution method, apparatus, chip and electronic device

Abstract

This application discloses a power-on operation execution method, apparatus, chip, and electronic device, belonging to the field of computer technology. The method includes: after the chip is connected to a host, when the frequency of the chip's first clock signal switches to a stable state, starting the chip's processor; receiving a reset signal sent by the host, the reset signal being sent after the frequency of the host's second clock signal switches to a stable state; and performing a power-on operation in response to the reset signal; wherein the time point when the frequency of the first clock signal switches to a stable state is earlier than the time point when the second clock signal switches to a stable state. Since the time point when the frequency of the first clock signal switches to a stable state is earlier than the time point when the second clock signal switches to a stable state, it is equivalent to advancing the processor startup process before receiving the reset signal. Therefore, there is no need to perform the processor startup operation during the power-on process, thereby shortening the time consumed by the chip's power-on process.
