The present invention adopts a kind of method and system reducing smart machine stand-by power consumption, for wake events produced in smart machine software, by corresponding setting, forbid corresponding wake events write hardware, thus reducing the number of times waking smart machine up, power consumption when reduction smart machine is standby, extends the use time of smart machine.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the invention will be further described.
Fig. 1 is the flow chart of the method for the invention；
Fig. 2 is the structure composition frame chart of system of the present invention.
Detailed description of the invention
The present invention, under smart machine holding state, can reduce stand-by power consumption further, extends stand-by time, improves the use time of smart machine.
With reference to shown in Fig. 1, the preferred embodiments of the present invention provide a kind of method reducing smart machine stand-by power consumption, including:
Inquire about and record all of application event in the standby state；
Application event filters out all of standby wakeup event；
Detect the interval of described wake events and the size of fixing threshold values；
Identify the interval time of the wake events more than or equal to fixing threshold values；
The corresponding wake events write hardware that will identify that.
Smart machine is when holding state, and the application of any one event is all undertaken by event generator, and each application event all has the event flag position of correspondence, therefore, can inquire about and record all of application event according to the flag bit of application event.Different application events, flag bit is different, and representative applying type is also different, therefore, can filter out all of standby wakeup event according to the flag bit of application event.
But not all wake events is required for waking smart machine up, some application software can wake smart machine up through the set time through setting, the sequence of certainly leaving being also likely to be application software itself causes, the generation of these wake events only can waste a power consumption for smart machine, reduces the use time of smart machine.Therefore, the interval of wake events, by arranging a fixing threshold values, is rejected less than the wake events of fixing threshold values, is therefrom identified the interval time of the wake events more than or equal to fixing threshold values by the present invention.
Identified wake events can be written in kernel events chained list (Kernel), for the interval wake events less than fixing threshold values, by wake events is modified, including revising the flag bit of wake events or redirecting the sensing of wake events, forbid these wake events are write kernel events chained list.
For the wake events in write kernel events chained list, it is necessary to reading wake events from kernel events chained list, and detect the wake events read the need of write hardware, if it is not required, then forbid write hardware, otherwise, write hardware is to wake smart machine up.
The present invention is detected by wake events produced by the application software in smart machine, is foreclosed by the wake events that non-user needs, and promotes smart machine stand-by time, extends smart machine and uses the time.The present invention has been used successfully in the systems such as a31/a31s, and through effectively detection, complete machine stand-by power consumption reduces more than 30%, have effectively achieved content of the present invention.
The preferred embodiments of the present invention additionally provide a kind of system reducing smart machine stand-by power consumption, shown in reference Fig. 2, including:
Event module, for inquiring about in the standby state and recording all of application event；
Filtering module, for filtering out all of standby wakeup event in application event；
Detection module, for detecting the interval time of wake events and the size of fixing threshold values；
Identification module, for identifying its interval time of the wake events more than fixing threshold values；
Kernel logging modle, before writing hardware for the described wake events that will identify that, interval time is write kernel events chained list more than or equal to the wake events of fixing threshold values, and revises the interval time of the wake events less than fixing threshold values, forbid its write kernel events chained list；
Hardware judge module, before the corresponding wake events that will identify that write hardware, reads wake events from kernel events chained list, and detects the wake events read the need of write hardware described in being used for；
Writing module, for the wake events write hardware that will identify that.
All of application event is inquired about and recorded to described event module in the standby state by the flag bit of application event.
Described filtering module filters out all of standby wakeup event according to the flag bit of application event in application event.
Described kernel logging modle be modified the flag bit of wake events or redirect wake events point to amendment interval time less than the wake events of fixing threshold values.
Implementing with reference to content described in above method in described system, described system can be completely achieved the content in described method.
The above, simply presently preferred embodiments of the present invention, the invention is not limited in above-mentioned embodiment, as long as it reaches the technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
