Title: FREQUENCY SWITCHING METHOD AND APPARATUS, AND COMPUTER READABLE STORAGE MEDIUM
Abstract:
Disclosed in an embodiment of the present invention is a frequency switching method. The method comprises: obtaining bandwidth requests of all CPUs, and determining a working frequency point required by a DDR; determining a working bandwidth occupied rate of the DDR according to a DDR busy-idle state indication signal; determining, according to a real-time working state of a system, a time point for switching a frequency by the DDR; on the time point for switching the frequency by the DDR, generating a frequency switching request according to the working frequency point required by the DDR and a current working frequency point of the DDR; and switching the frequency of the DDR according to the frequency switching request. Also disclosed in embodiments of the present invention are a frequency switching apparatus and a computer readable storage medium.
