ABSTRACT:
A method for adjusting execution frequency of a central processing unit (CPU) in an electronic apparatus is provided. The method includes the steps of: (a) obtaining a state of a CPU workload in real time; (b) checking a property frequency and an execution frequency of the CPU; (c) determining whether the state of the CPU workload is in a higher state or a normal state; (d) determining whether the execution frequency of the CPU needs to be changed according to the state of the CPU workload; (e) calculating a frequency value according to the property frequency and the execution frequency, if the execution frequency of the CPU needs to be changed; (f) generating a suitable frequency according to the frequency value; and (g) adjusting the execution frequency of the CPU according to the suitable frequency. A related system is also disclosed.
