Abstract
The invention discloses a method and a device for lowering the power consumption of an intelligent terminal. A DDR (Double Data Rate) with high power consumption is taken as an object of power consumption lowering, and the frequency of the DDR is adjusted according to the frequency change of a CPU (Central Processing Unit), so that the frequency of the DDR is matched with the load situation of the CPU, electric energy consumption caused by continuous high-frequency working of the DDR is avoided, the power consumption lowering of a whole machine is facilitated, more power is saved for the intelligent terminal, and the standby time and service time are prolonged.
Description
Technical field
The present invention relates to intelligent terminal technical field, particularly relate to a kind of method and apparatus of intelligent terminal reducing power consumption.
Background technology
Along with the development in intelligence epoch, the program that intelligent terminal is installed gets more and more, and various function element constantly commercially occurs, as: the various sensors such as nfc, otg, fingerprint, cause the power consumption of intelligent terminal exponentially to rise.
Because the battery capacity of intelligent terminal can not unrestrictedly increase, power consumption has become one of most important factor affecting user's use.
Summary of the invention
Based on above-mentioned situation, the present invention proposes a kind of method and apparatus of intelligent terminal reducing power consumption, to reduce power consumption, extend the service time of intelligent terminal.For this reason, the scheme of employing is as follows.
A method for intelligent terminal reducing power consumption, comprises step:
Read the ongoing frequency of CPU;
Search the default corresponding relation of cpu frequency and DDR frequency, determine the DDR frequency that CPU ongoing frequency is corresponding;
DDR ongoing frequency is adjusted to the frequency of searching and determining.
A device for intelligent terminal reducing power consumption, comprising:
Cpu frequency read module, for reading the ongoing frequency of CPU;
Frequency relation searches module, for searching the default corresponding relation of cpu frequency and DDR frequency, determines the DDR frequency that CPU ongoing frequency is corresponding;
DDR frequency adjustment module, for being adjusted to the frequency of searching and determining by DDR ongoing frequency.
The method and apparatus of intelligent terminal reducing power consumption of the present invention, using the object of DDR more for power consumption as reducing power consumption, the frequency of DDR is regulated according to the frequency change situation of CPU, the frequency of DDR and the loading condition of CPU are matched, avoid the power consumption that the work of DDR continuous high frequency brings, for complete machine reducing power consumption has made contribution, make intelligent terminal more power saving, stand-by time is more of a specified duration.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of the method for intelligent terminal reducing power consumption of the present invention;
Fig. 2 is the structural representation of the device of intelligent terminal reducing power consumption of the present invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that embodiment described herein only in order to explain the present invention, do not limit protection scope of the present invention.
The method of intelligent terminal reducing power consumption of the present invention, as shown in Figure 1, comprises the following steps:
The ongoing frequency of step s101, reading CPU.
DDR (internal memory) is one of place that outside CPU, power consumption is larger, and its frequency of operation is generally in maximum frequency.And the frequency of CPU can rise and fall along with the increase and decrease of handled data volume, when the data volume of CPU process is less namely load is lighter time, CPU is in low frequency operation state, and DDR still adopts highest frequency, causes the wasting of resources.This method reduces its power consumption from the angle reducing DDR frequency just, but the reduction of DDR frequency can not be arbitrary, should be to carry out under the prerequisite ensureing normal work, namely should adapt with the frequency of CPU.For this reason, first step of this method obtains the current frequency of CPU.
Step s102, search the default corresponding relation of cpu frequency and DDR frequency, determine the DDR frequency that CPU ongoing frequency is corresponding.
Adopt this method should pre-set the corresponding relation of cpu frequency and DDR frequency, in this corresponding relation, DDR frequency should be positively related with cpu frequency, the i.e. high-frequency of the corresponding DDR of the high-frequency of CPU, the low frequency of the corresponding DDR of low frequency of CPU, but concrete corresponding relation should be determined on a case-by-case basis.
Step s103, DDR ongoing frequency is adjusted to the frequency of searching and determining.
Now, DDR frequency is in a level that the work of CPU can be coordinated not waste again electric energy, and can according to the change of cpu frequency dynamic adjustments, thus reduce power consumption, achieve object of the present invention.
The device of intelligent terminal reducing power consumption of the present invention is the device corresponding with said method, as shown in Figure 2, comprising:
Cpu frequency read module, for reading the ongoing frequency of CPU;
Frequency relation searches module, for searching the default corresponding relation of cpu frequency and DDR frequency, determines the DDR frequency that CPU ongoing frequency is corresponding;
DDR frequency adjustment module, for being adjusted to the frequency of searching and determining by DDR ongoing frequency.
As a preferred embodiment, in described default corresponding relation, DDR frequency and cpu frequency correlation.
As a preferred embodiment, described frequency relation searches module also for arranging described default corresponding relation according to the data volume processed in the CPU unit interval.
To sum up, the method and apparatus of intelligent terminal reducing power consumption of the present invention, according to the change of cpu frequency, dynamic adjustments is carried out to the frequency of DDR, compare the classic method always adopting high-frequency work, the power consumption of DDR presents significant reduction, for extending complete machine stand-by time and providing support service time.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
