Abstract

This disclosure relates to a clock protection circuit, a clock protection method, a storage medium, and electronic equipment. [Solution Technology] This clock protection circuit includes a clock monitoring and measurement module that performs fault monitoring and measurement on a functional clock signal generated by a functional clock source based on a backup clock signal generated by a backup clock source to obtain fault monitoring and measurement results, and determines a target clock signal from the backup clock signal and the functional clock signal based on the fault monitoring and measurement results, and a clock processing module that determines a safety clock signal to be transmitted to the functional module based on the target clock signal. The embodiments of this disclosure are advantageous in ensuring the reliability of the clock signal used by the functional module, ensuring the normal and reliable operation of the functional module, and ensuring the normal operation of the chip on which the functional module is located.
