Embodiment Construction

[0082] At present, portable devices basically use embedded processors as their central control unit. The power consumption of the embedded processor also affects the power consumption of the device to a large extent, affecting the use time of the device. When an embedded processor handles different tasks, the actual required processing speed is also different. If the operating frequency of the embedded processor can be adaptively adjusted to the minimum frequency actually required according to the task to be processed, the power consumption of the embedded processor will be effectively reduced. In order to make those skilled in the art understand the present invention better, the method for adjusting the embedded processor frequency provided by the present invention will be specifically described below in conjunction with specific embodiments, figure 1 is a flowchart of the method.

[0083] When the portable device is running, it is necessary to periodically measure the idle...

Abstract

The invention discloses a method for adjusting the frequency of an embedded processor. The method comprises the following steps: measuring the idleness value of the embedded processor; when the idleness value is higher than a first threshold value, reducing the frequency of the embedded processor; and when the idleness value is lower than a second threshold value, increasing the frequency of the embedded processor. The method can ensure that not only the embedded processor can operate various tasks normally, but also the embedded processor can operate at a lower frequency through regulating the frequency, thereby reducing the power consumption of the embedded processor, and further reducing the power consumption of portable devices which adopt the embedded processor, and prolonging the working time of the portable devices. The method further discloses an embedded processor frequency regulating device, and the corresponding method and device for regulating the frequency of a mobile terminal processor.

Description

technical field [0001] The invention relates to an energy-saving method for an embedded processor, in particular to a method and device for achieving energy-saving effects by adjusting the frequency of an embedded processor, and a corresponding method and device for adjusting the frequency of a mobile terminal processor. Background technique [0002] With the continuous improvement of people's living standards, portable devices (such as mobile terminals, handheld computers, digital companions, etc.) are also developing rapidly, especially the development of mobile terminals is advancing by leaps and bounds. Portable products are increasingly feature-rich, and with it comes the question of how to extend the usage time of portable devices with limited battery power. [0003] In order to prolong the use time of portable devices, the industry currently adopts two methods. One is to develop new batteries with higher energy density; the other is to work hard on the energy conversi...
