When running graphic intensive game, the load on CPU can generally be not at maximum value, and maximum allowable operation frequency
The restriction of rate can not impact game process (gameplay) or number of pictures per second.This can be depending on game, thereby increases and it is possible to need
Best cpu clock frequency be can determine to avoid conservative approach (clock rate when it still can allow quite high of user experience is influenced
Degree) or process for selective.
According to various embodiments, conservative approach can be：It is more than to set that cpu frequency, which is defined in, which prevents the maximum power of CPU,
The point of fixed point, and it is still maintained at less than the constant discharge rate of battery maximum discharge rate, which allows GPU and other system components
Swimmingly run.This, which can be provided to the user, (wherein may not be used similar to system using exchange (alternating current) power supply
To battery apply electric power limitation) when game experiencing.
This " conservative " controlling mechanism can be executed by embedded controller.First, SMBus (system pipes are run through by reading
Manage bus) intelligent battery group data, or by using the analog-digital converter across Low ESR detection resistance device
(ADC), battery current is measured using EC, system can be determined whether it is expected to reduce power consumption.Then, EC can be (advanced to match by ACPI
Set and power interface) to CPU send order, inform that maximum frequency of operation is decreased to empirically predetermined value by CPU.
If, can there are other benefits to user using more selective method.This benefit can be system
The reduction of power consumption allows battery life longer and the game process of user is longer.This process for selective can be intelligently
Reduce the maximum clock frequency of CPU so that user experience and FPS can be unaffected.
The value may depend on application program, and certain game may be present, the extremely low CPU bandwidth of tolerable and can not be right
Game process impacts.According to various embodiments, it is possible to provide at least one of following two " selectivity " methods.
First " selectivity " method can relate to run program in the application layer of operating system (OS) and which is tracked to play
Journey is currently running or which game executable file (executables) has been turned on.Based on library (library) or white list
(whitelist), application program then can notify the best maximum frequency of operation of the EC CPU, or can be otherwise
Directly reduce maximum frequency itself.
Second " selectivity " method can relate to empirically reduce cpu frequency and measure user's experience measurement of quantization
(such as number of pictures per second).After reducing cpu frequency, reduce if detecting apparent FPS, can be removed or increase CPU most
Big value.Reduce cpu frequency mechanism can it is identical as the mechanism in first choice method-by notifying EC or directly reducing CPU
Maximum frequency.
