Description

At present, with the increasing popularity of smart terminals, especially mobile phone terminals, the increasingly powerful "multi-core, large screen" mobile phone terminals are increasingly placed in front of consumers.

Here, the embodiment of the present invention mainly uses the Nvidia Tegra mobile phone intelligent platform as an example, but the terminal of the present invention is not limited to a mobile phone terminal, and includes a portable terminal such as a portable notebook or an IPAD, and the platform is not limited to the Nvidia Tegra here. platform. Under the original T-Skin temperature control strategy of the Nvidia Tegra platform, the application (App) Profile mechanism was introduced, and the corresponding upper application App Picker was developed. In the embodiment of the present invention, when the T-Skin temperature control strategy is closed, when running a specific APP on the terminal, the hardware performance of the mobile terminal can be fully utilized as much as possible, and the phenomenon of not being smooth or stuck can be caused, and Double rate synchronization of mobile terminals DDR SDRAM (Double Data Rate Synchronous Dynamic Random Access Memory), referred to as DDR, improves the user experience by reducing power consumption and improving the power of the CPU to ensure good application results for the APP. A summary explanation of several terms in this paragraph: The Nvidia Tegra is a model, code: Project Kal-El, the world's first mobile quad-core processor (4 Cortex- shown at NVIDIA's 2011 MWC) A9 core). The T-Skin is an abbreviation of Temperature Skin, that is, the terminal surface temperature, and here is a CPU frequency modulation strategy for adjusting the temperature of the terminal surface. The App Profile is an attribute set of the App, such as a CPU frequency value, a DDR frequency value, and the like when the App is run. Only the CPU frequency value and the DDR frequency value are used in the text. The App Picker is an Android apk application name, and the application can enumerate all the apks installed in the terminal, including the application icons of the apk, the application name and the package name, and can be selected for each application, as shown in FIG. 2, For checked applications ^: Adjust DDR frequency processing.

Specifically, the technical solution of the embodiment of the present invention is described by taking the Nvidia Tegra mobile intelligent platform as an example, and includes the following three aspects:

I. T-Skin temperature control strategy: The temperature control strategy of the Nvidia Tegra platform to reduce the power consumption of the terminal by adjusting the CPU frequency. The principle is that when the terminal temperature exceeds a certain threshold T, the T-Skin strategy will force the CPU operating frequency to be reduced. Reduced power consumption. The threshold T in this paragraph is the temperature at which the terminal feels severely hot, such as 55 degrees Celsius, which needs to meet the specified standards.

Second, the App Profile mechanism: Based on the original T-Skin temperature control strategy of the Nvidia Tegra platform to adjust the CPU frequency, the App Profile mechanism is introduced, which can set the frequency value suitable for DDR work for different APPs of the mobile terminal to reduce the mobile phone. Power consumption. The selection of this frequency value can be based on the measured empirical value of the alternative. The measured empirical value is the actual measured value of the DDR frequency. The DDR works at a certain frequency point, that is, the normal working frequency supported by the hardware. For example, the frequency value of the DDR operation of the Nvidia Tegra 3 platform is: 25500, 51000, 102000, 204000, 266500, 380000, 533000kHz, etc. Third, the App Picker upper application is presented as a human-computer interaction interface. Based on the user experience, the corresponding upper-layer application App Picker is developed. Selecting an APP in the application means that for the APP, the App is adopted. The Profile mechanism, App Profile's DDR frequency reduction (the feeling of the user is the decline of the phone fever) mechanism works for it, if not selected, the App Profile mechanism is not used.

In the actual application, 1) the traversal list list of the default App may be preset according to the above experience value, and the list includes an APP list that consumes a large amount of power, and the APP that has a large power consumption is found to be running, belonging to the APP list. Similar to the black-and-white list processing rule, it can be understood that the APP that consumes a large amount of power is blacklisted, and an App Profile mechanism is required. 2) The default App traversal list list may be preset according to the above experience value. The table includes an APP list that consumes a large amount of power consumption, and may further add or delete an APP existing in the APP list, and the default APP. The list is updated. Similarly, it is found that the APP that consumes a large amount of power is running, and belongs to the updated APP list, and the App Profile mechanism is required.

Regardless of the default APP list or the updated APP list, except for the data content, but for the basic data format attribute of the table, it is the traversal list of the specific App, and each item in the table contains The DDR frequency or the T-Skin switch value ensures that when the application traverses the entry list item in the APP list, the system DDR value or T-Skin is set to the value in the entry in the corresponding APP list, otherwise, the application is exited or started. In other non-list applications, restore the DDR or T-Skin switch to its original initial value.

In summary, in order to provide a better experience for the user, that is, at least the temperature control of the terminal can be implemented, and the impact of the lowering of the operating frequency of the CPU on the performance of the mobile terminal is avoided, and the smooth running of the application on the terminal is ensured. Mechanism, this mechanism acts as a powerful assistant to the platform's own T-Skin function, and the two work together to achieve a better balance between performance and power consumption. In addition, the matching upper application App Picker provides an upper layer interaction interface for the application control terminal temperature (mainly reducing the terminal temperature) for the application in the embodiment of the present invention, which is convenient for the user to select The scheme for controlling the temperature of the terminal of the embodiment of the present invention is enabled for which installed APPs. The following is a specific example of the embodiments of the present invention.

Device embodiment:

FIG. 3 is a schematic diagram of a module according to an embodiment of the present invention. There is a default setting APP list on the mobile terminal for adjusting the profile adjustment mechanism. The device at least includes: a CPU temperature control policy module 100, and an App Profile adjustment module 110. It should be noted that the CPU temperature control policy module 100 is a refinement of the temperature control policy module, and the App Profile adjustment module 110 is a refinement of the adjustment module.

The CPU temperature control strategy module 100, also known as the Nvidia Tegra platform's own T-Skin temperature control strategy module, is configured to implement T-Skin based control, by adjusting the operating frequency of the CPU to control the temperature of the mobile terminal, specifically, achieving temperature The principle of the control is to reduce the power consumption to reduce the temperature by reducing the CPU frequency. The App Profile adjustment module 110 includes: a DDR adjustment policy sub-module 1102 composed of an App Profile adjustment mechanism, also called an App Profile to adjust the DDR frequency temperature. The control mechanism module is configured to adjust the DDR frequency according to the App Profile adjustment mechanism. The principle of adjusting the DDR is to adjust the frequency of the DDR to achieve the same goal of reducing power consumption to lower the temperature, but the two functions are different. The two modules CPU temperature control strategy module 100 and App Profile adjustment module 110 work together to output the respective function results of the two modules to the control module 120 for final control, that is, to implement terminal temperature control for the APP.

The App Profile adjustment module 110 may further include: a user interface display sub-module 1101, also referred to as an App Picker upper application module, configured to provide a user interface display to the user, when the user needs to randomly update the default settings APP list, Check the existing APP or add power app.

As shown in FIG. 3, the device further includes: a monitoring module 113 configured to monitor current system processes and threads, and find that an APP occupies too many processes or threads, for example, reaches a preset threshold T1, and prompts the user to know that Use the pop-up dialog box or the way of alarm prompts. At this time, use The user displays the user interface provided by the sub-module 1101 through the user interface, and checks whether the APP exists in the default setting APP list, and if so, directly selects, otherwise, the APP is added. The preset threshold T1, for example, the Android Dalvik virtual machine has a limit of up to 128 threads. Generally, the number of simultaneous threads started in one application is about 5, which is for reference only, and is not limited to the example here, according to Model and system configuration are different.

Figure 4 is a flow chart of the T-Skin function of the Nvidia Tegra platform. Taking the mobile terminal as an example, the temperature control policy control process includes the following steps:

Step 200, running a large APP (such as a 3D game, etc.) in the mobile terminal;

Step 210: Running the APP requires more system resources, increasing the power consumption of the mobile phone, and causing the temperature of the mobile terminal to exceed the threshold T;

Step 220, determining whether the T-Skin function switch provided by the system is turned on; if the switch is turned on, performing step 230; if the switch is off, performing step 250;

Step 230, the system reduces the operating frequency of the CPU to reduce system power consumption;

In step 240, if the heat generation of the system decreases and the temperature of the mobile terminal is lower than the threshold T, the T-Skin function switch is turned off, and the temperature control strategy control process is ended.

After performing step 240, the T-Skin strategy effectively reduces the fever of the mobile phone (but may cause a slight decrease in the performance of the mobile phone);

Step 250, the surface temperature of the mobile phone terminal will continue to rise. If the temperature exceeds the threshold T, the temperature control strategy control process is continued.

After performing step 250, the user experience will be seriously affected by the hot phone. That is to say, the T-Skin temperature control strategy is only used to control the temperature of the mobile terminal, and the user is not very satisfied with the actual effect, and the measures that consume power consumption or system performance by reducing power consumption are affected.

The temperature control is performed in the manner that the platform only adjusts the CPU frequency, mainly to reduce the temperature of the mobile phone terminal. The following embodiments of the present invention provide a method for controlling the temperature of the terminal for different APPs, that is, when running a specific APP. , set its DDR frequency, achieve a reduction The purpose of the terminal temperature largely avoids the occurrence of stagnation and slickness, effectively improves the user experience, and finds a suitable balance point between reducing power consumption and system performance.

It should be noted here that, in comparison with the existing temperature control strategy, the effect of the T-Skin temperature control strategy of the above platform has certain defects, and the AP33 of the Nvidia Tegra mobile intelligent platform is taken as an example. The AP33 platform is a Nvidia Tegra series chip. The AP33 platform has 4+1 CPU cores, 1.5G frequency, and Android 4.0 system. The platform itself has Dynamic Voltage and Frequency Scaling (DVFS). And its unique T-Skin temperature control strategy. However, in actual use, it has been found that the local maximum temperature of the mobile phone can still be as high as 55 ° C or more, and the burn is severe. The T-Skin temperature control strategy that comes with the platform, when the T-Skin function is turned off, the temperature of the mobile terminal may rise to an extent unacceptable to the user, seriously affecting the user experience. As the temperature of the mobile phone rises, in order to avoid this situation, the system will turn on the T-Skin temperature control strategy to alleviate the heat generated by the power consumption of the mobile phone. The principle is that when the terminal temperature exceeds a certain threshold T, the T-Skin strategy It will force the CPU operating frequency to be reduced, thus reducing power consumption.

However, turning on the T-Skin temperature control strategy is used to alleviate the heat generated by the power consumption of the mobile phone. Lowering the CPU operating frequency will affect the performance of the entire mobile phone. For example, when running some applications that have high requirements on system resources, a screen will appear. The phenomenon of not smooth or even Caton directly affects the brand value of mobile phones. That is to say, when the T-Skin function is turned on, the temperature of the mobile terminal is reduced to some extent due to the lowering of the operating frequency of the CPU, that is, the power consumption of the terminal is reduced at the expense of performance. As a result, the user experience has dropped dramatically, and large APPs are likely to be unsmooth or stuck. Therefore, the existing temperature control strategy of the AP33 platform that relies solely on T-Skin to adjust the CPU frequency is not ideal for the temperature control of the mobile terminal, and needs further improvement and improvement.
