Embodiment Construction

[0012] see figure 1 As shown, a method for reducing power consumption of an electronic device in the present invention realizes the function of reducing the operating frequency of a processor in a standby state through a keyboard, a processor, a timer, a crystal oscillator, and an operating frequency controller. Wherein, the processor is respectively connected with the keyboard, the timer and the operating frequency controller, and the operating frequency controller is also connected with the crystal oscillator. The function of the keyboard is to detect the keyboard signal input by the user and transmit the keyboard signal to the processor. The function of the timer is to set a cycle time, and the processor detects whether there is an interruption within the time set by the timer, and selects a corresponding working frequency according to the detection result. The function of the crystal oscillator is to generate the clock frequency signal f 1 . The function of the operatin...

Abstract

The method of reducing power consumption of electronic equipment includes the following steps: 1. for the timer to time; 2. to judge whether to have interruption during the time, and resetting the timer and retiming if there is interruption; and 3. if there is no interruption before reaching the set time, for the system to control the frequency of the processor via the work frequency controller, and for the clock signal the crystal vibrator outputs to pass through the frequency divider and the demultiplexer and for the demultiplexer to output signal as new input clock signal of the processor.

Description

【Technical field】 [0001] The present invention relates to a method for reducing power consumption of electronic equipment, specifically, relates to a method for reducing power consumption of electronic equipment in a standby state. 【Background technique】 [0002] With the rapid development of microelectronics technology, users' demand for consumer electronic equipment, especially portable information equipment, has also greatly increased, which has promoted the further improvement of the performance of electronic equipment. For electronic equipment using batteries, designers in the past have more The reason is to consider two aspects of its optimized space: speed and volume, while ignoring its third aspect, namely power consumption. Reducing the power consumption of electronic equipment makes the electronic equipment have a longer running time and can effectively extend the life of the battery. This allows users to no longer only pay attention to the performance of electroni...
