In the description of the present invention, the step numbers are merely used for convenience of description or for convenience of reference, and the sequence numbers of the steps do not mean the execution sequence, and the execution sequence of the steps should be determined by the functions and the inherent logic, and should not constitute any limitation to the implementation process of the embodiment of the present invention.
Referring to fig. 1, the electronic book of the present invention includes: the low-power-consumption entry processing module 100 is used for receiving a low-power-consumption entry request, executing corresponding sleep entry processing, and configuring an android system lock strategy, namely, forbidding application lock holding when the system is in a low-power-consumption mode, transmitting a low-power-consumption mode mark to a driver, and then initiating a deep sleep process of an android system kernel; the low-power management module 200 is configured to control the system to enter a low-clock and low-load micro core to operate in a low-power mode; and a low power consumption wake-up module 300 for responding to a wake-up request of an external device. The ink screen of the electronic book product has a hysteresis effect, namely after the electric field at two ends of the capsule is removed, black and white particles in the capsule still keep at the position and cannot move for a long time (at least one month), and the characteristic can meet the requirement that the electronic book can still keep displayed contents for a long time after power failure. The invention utilizes the characteristic that the device of the electronic book is non-volatile when power is off, provides a reading mode with low power consumption, reduces the power consumption of the electronic book in a use scene, and prolongs the endurance time.
The low power entry processing module 100 calls the lock management module 110 and the first module 120 when performing the entry to sleep process. And the lock management module 110 is configured to summarize current locks of the system and remove a CPU lock in the mwakelocksummery when executing corresponding processing for entering sleep. The first module 120 is configured to turn off the GPU, the master core power supply, and the clock. The embodiment of the present invention, as shown in fig. 1, further includes: the application management module 400 skips the suspend mode when the electronic book initiates the android to enter the hibernation process and controls the application program to respond to the screen being turned off.
The method in the embodiment of the invention, as shown in fig. 2, comprises the following steps: the electronic book receives a low-power-consumption entering request, a power supply management module executes corresponding sleep entering processing, and after a low-power-consumption mode mark is transmitted to a driver, a deep sleep process of an android system kernel is initiated; the sleep processing comprises adjusting a lock strategy of the android system, and forbidding application lock holding when the system is in a low power consumption mode; and when the electronic book is in the low power consumption mode, responding to the awakening request of the external equipment and controlling the self-refreshing of the memory.
In the embodiment of the invention, a low-power-consumption mode interface is added to a power management module (PowerManager) of an electronic book and is used for receiving a low-power-consumption entering request initiated by an application program. When the application program enters the depth, the system keeps the interrupt of the external device to respond to the page turning request of the user, but the memory can be automatically refreshed, and the irrelevant power supply and the clock in the system can be turned off, so that the power consumption is reduced.
If the system judges that the user operation is not received within a certain time or the application initiates a request for entering the low power consumption mode according to the reading behavior characteristics of the user, as shown in fig. 3, at this time, the power management module executes corresponding sleep entering processing (i.e. initiates a gotoSleep), and simultaneously transmits a low power consumption mode mark to the driver, and the driver activates the function of waking up in the low power consumption mode. And the android system enters a deep sleep process through Kernel Standby, namely the android system enters a low power consumption mode after the Kernel is in sleep. When equipment that needs to awaken up is entering equipment dormancy like touch-sensitive screen, electromagnetism pen drive, sets up to: allowing the low power mode to wake up the system. After the device enters a low-power-consumption sleep mode, a micro core running at a low frequency is in a wait wakeup state, a memory of the micro core can enter self refresh, other modules such as a GPU (graphics processing unit) and a power supply and a clock of a main core can be closed, and the power consumption of a system is lowest after the micro core enters the mode.
When an application initiates a process of entering sleep processing, the current lock of the system is summarized (updateWakeLockSummaryLocked), the lock policy of the android is adjusted in the process, when the system is in a low power consumption mode, the application program is not allowed to hold the lock (namely, the application program is forbidden to hold the lock), the system can be prevented from entering the low power consumption mode due to the fact that the system is occupied by the lock, and power consumption abnormity caused by the fact that the application or the system holds the lock for a long time is avoided. Namely, CPU locks in a result mWakeLockSummary obtained after the current locks of the system are aggregated are removed. Namely, the CPU lock is forbidden under the android system low power consumption mode in the electronic book.
When an application program initiates an android system to enter a sleep process, the application enters a pause state after responding to a screen-off behavior (screen turning off interface), and if a click event does not respond after the application program confirms, the click event is discarded; if the click event is reported after the application is confirmed, the delay is increased. To ensure that the application does not lose the screen click event in this state, the application skips application suspension in response to the screen being turned off, as shown in FIG. 4. After initiating a request for entering low power consumption, an application program or a system responds to screen-off and judges whether a low power consumption mode is adopted, if so, the application program or the system directly enters a deep sleep process through a Kernel Standby; if not, the application enters the suspended mode. Thus, after entering the low power consumption state, the application can directly respond to the click event after the user clicks the screen.
The invention has effective acceptance test on the android X platform of a certain chip platform, has obvious effect, the power consumption of the chip platform in the corresponding reading mode before optimization is 400mW, and the power consumption is only 18mv after optimization. Through the embodiment of the invention, the power consumption of the electronic book is reduced, and the endurance time of the electronic book is effectively prolonged.
