Abstract

The invention discloses a method for adaptive frequency regulation, which is used for controlling the operating frequency of a central processing unit of an electronic device and comprises the steps of: obtaining at least one interruption service requesting time period and whereby calculating to generate a corresponding calculating result; and according to at least a comparison result of the calculation result and a predetermined range, dynamically determining a target frequency of the operating frequency of the central processing unit, so that the operating frequency is set according to the target frequency when the central processing unit is processed owing to the occurrence of next interruption, in order to realize adaptive frequency regulation. The invention further discloses an electronic device related thereto. According to the invention, the best processing efficiencies, which meet the different demands of various files respectively, can be provided without excessive power consumption, thereby reaching the best overall efficiency.

Description

technical field [0001] The present invention relates to Interrupt Service Request (ISR) control, in particular to a method for performing adaptive (Adaptive) frequency adjustment and related electronic devices. Background technique [0002] In order to achieve the purpose of saving power, the portable electronic devices implemented according to the related art usually have a deliberately lowered operating frequency. However, once an interrupt occurs, the portable electronic device must perform necessary determination and processing procedures, and the above-mentioned deliberately reduced operating frequency will cause delays in the portable electronic device's processing of immediate events. As a result, the overall system load of the portable electronic device for interrupt processing increases significantly as the operating frequency decreases. [0003] In order to solve the above problems, the related art provides a solution for maintaining high-speed operation in order ...
