Description

Configuration method, system and mobile terminal of a power management chip

technical field

The invention relates to the communication field, in particular to a configuration method, system and mobile terminal of a power management chip.

Background technique

The power management chip is used to manage the power supply of all modules of the mobile terminal. The power management chip is one of the most important chips of the mobile terminal. The mobile terminal will have multiple modes during use; the number of modes is set by the mobile terminal manufacturer. In the mobile terminal, because the function is monotonous: the mobile terminal is only used for telephone and information, so there are often only four modes for power management: flight mode in the bright screen state, flight mode in the off screen state, and normal use in the bright screen state mode, the normal use mode of the off-screen state. The so-called flight mode in the bright screen state means that the power management chip turns off all the power supplies of the radio frequency part of the mobile terminal, but turns on other power supplies. The so-called flight mode in the off-screen state means that the power management chip turns off all power supplies of the mobile terminal. The normal use mode of the so-called bright screen state means that the power management chip turns on all the power supplies of the mobile terminal. The normal use mode of the so-called off-screen state means that the power management chip only turns on the power supply of the radio frequency part of the mobile terminal.

In addition to the basic functions of telephone and information, the current mobile terminals also have many functions such as camera, WIFI, Bluetooth, etc., and there will be more modes for power management. Since the power supply of the power management chip is different in each mode, it needs to be configured according to the mode; in the prior art, each mode is equipped with a set of corresponding power management chip settings. B, it will obtain the settings of the power management chip corresponding to mode B, and then write the settings into the power management chip; among them, the so-called settings of the power management chip are actually the settings of a series of registers of the power management chip, that is, , to enable and disable the power supply of each module by writing corresponding register settings to the power management chip.

Therefore, in the prior art, a power supply mode corresponds to a set of register settings of a power management chip. When the mobile terminal switches to a new power supply mode, the register settings of the corresponding power management chip in this mode are obtained and then written into the power management chip. chips; in this method of the prior art, there are many register duplication settings, and the efficiency is low. WIFI power supply is turned off), but according to the existing technology, when the power supply mode of the mobile terminal is switched from mode A to mode B or from mode B to mode A, the power supply of WIFI will be turned off. The operation of turning off the power of WIFI when switching between modes is repeated. The above examples are just the tip of the iceberg. In the actual use of mobile terminals, especially mobile terminals with complex functions, there are more repetitive operations and lower execution efficiency.

Detailed ways

The invention provides a configuration method, system and mobile terminal of a power management chip. In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Please refer to Fig. 1, the configuration method of the power management chip provided by the present invention includes steps:

S10. Pre-save the settings of the registers corresponding to the power management chip in various power supply modes in the memory of the mobile terminal. Among the settings of the corresponding registers in various power supply modes stored in the memory, there is a setting of the register corresponding to the power supply mode as the default value of the register after the power management chip is reset, that is, the default value of the power management chip after reset. The power supply mode is one of various power supply modes stored in the memory, so as to ensure that the power management chip can still work normally after the power management chip is reset.

The memory is a power-fail non-volatile memory, such as emmc, flash, eeprom, etc. Among them, the memory stores the settings of the corresponding registers in various power supply modes as follows: power supply mode 1 corresponds to register setting 1, power supply mode 2 corresponds to register setting 2, power supply mode 3 corresponds to register setting 3, ..., power supply mode N corresponds to register Set N. Wherein, N is a natural number greater than or equal to 2.

S20. When the power supply mode needs to be switched, according to the power supply mode to be switched to, acquire the register setting corresponding to the power supply mode in the power management chip. Specifically, various operating instructions of the mobile terminal are correspondingly established with various power supply modes in advance, and the corresponding power supply mode is found after receiving the operation command sent by the user to control the mobile terminal, and this power supply mode is the power supply mode to be switched to. Mode, according to the power supply mode that needs to be switched to, obtain the register settings corresponding to the power supply mode in the power management chip. The "pre-establishing correspondence between various operating instructions of the mobile terminal and various power supply modes" is specifically: operation 1 corresponds to power supply mode K1, operation 2 corresponds to power supply mode K2, operation 3 corresponds to power supply mode K3, ..., operation M Corresponding to the power supply mode KM. Among them, M is a natural number greater than or equal to 1, Kx (x is 1, 2, 3, ..., M) is a natural number greater than or equal to 1, and K1, K2, K3, ..., KM can be the same, instead In other words, the same power supply mode can correspond to multiple operations. For example, the user needs to supply power to the camera during the camera operation and the video chat operation, and both the camera operation and the video chat operation correspond to the power supply of the camera.

S30. Obtain register settings corresponding to the current power supply mode in the power management chip.

S40. Compare the register setting corresponding to the power supply mode to be switched to with the register setting corresponding to the current power supply mode, and obtain registers with different settings.

S50. Only write the settings of the registers in the power supply mode to be switched to that are different from the settings of the current power supply mode into the registers corresponding to the power management chip. That is, compare the register settings corresponding to the two power supply modes. After finding the registers with different settings, you only need to change the settings of these registers with different settings to complete the switching of the power supply mode, which greatly reduces the switching time of the power management chip. The number of registers that need to be set in the power supply mode improves the efficiency of power supply mode switching and saves battery power.

S60. After the power supply mode is switched, save the register setting corresponding to the current power supply mode in the power management chip. In order to execute step S30 when switching the power supply mode next time. Of course, after the power supply mode is switched, it is also possible to associate the operation instruction with the different registers and their register settings, and save them. When the user sends the operation instruction through the mobile terminal next time, it is not necessary to perform steps S20, S30 and S40. , directly execute step S50, which further saves the steps of comparison and improves the efficiency of power supply mode switching.

In the specific implementation of the present invention, taking three power supply modes as an example, the registers corresponding to these three power supply modes are set as follows:

Power supply mode 1 of the power management chip:

register address register set 1 0x0101 0x22 0x0102 0x02 0x0103 0x55 0x0104 0x18 0x0105 0x61 0x0106 0x52 0x0107 0x22 0x0108 0x88

Power supply mode 2 of the power management chip:

register address Register Set 2 0x0101 0x72 0x0102 0x02 0x0103 0x55 0x0104 0x18 0x0105 0x68 0x0106 0x52 0x0107 0x22 0x0108 0x88

Power supply mode 3 of the power management chip:

register address Register Set 3 0x0101 0x82 0x0102 0x02 0x0103 0x55 0x0104 0x18 0x0105 0x68 0x0106 0x82 0x0107 0x22 0x0108 0x66

Assume that the current power supply mode of the power management chip is power supply mode 3, the user needs to switch the power supply mode 3 to power supply mode 2 when operating the mobile terminal, and set the operation command as operation 2, then compare the power supply mode 3 and power supply mode 2 corresponding Register settings, get the registers that need to be set and their settings:

register address Register settings 0x0101 0x82 0x0106 0x82 0x0108 0x66

Therefore, just modify the setting of the register with address 0x0101 to 0x72, the setting of the register with address 0x0106 to 0x52, and the setting of the register with address 0x0108 to 0x88, and the transition from power supply mode 3 to power supply mode is completed. 2 switch. It can be seen that, in this example, only need to modify the three register settings to complete the switching of the power supply mode. In practical application, since the functions of mobile terminals are increasing, the power supply modes are also increasing, and the registers corresponding to the power supply modes are also increasing. Using the configuration method provided by the present invention can greatly reduce the modification of register settings, not only The switching efficiency of the power supply mode is improved, and the service life of the power management chip is also improved.

Moreover, since the corresponding relationship between operation 2 and register 0x0101 and register setting 0x72, register 0x0106 and register setting 0x52, register 0x0108 and register setting 0x88 is saved, when the user performs operation 2 next time, the register 0x0101, register The settings of 0x0106 and register 0x0108 can be modified, which saves the action of obtaining and comparing the register settings of the two power supply modes, and further improves the power supply efficiency.

Based on the configuration method of the power management chip provided in the previous embodiment, the present invention also provides a configuration system of the power management chip. As shown in FIG. Module 30.

The operation association module 20 is used to establish correspondence between various operation instructions of the mobile terminal and various power supply modes in the setting saving module. Specifically, operation 1 corresponds to the power supply mode K1 , operation 2 corresponds to the power supply mode K2 , operation 3 corresponds to the power supply mode K3 , . . . , and operation M corresponds to the power supply mode KM. Among them, M is a natural number greater than or equal to 1, Kx (x is 1, 2, 3, ..., M) is a natural number greater than or equal to 1, and K1, K2, K3, ..., KM can be the same, instead In other words, the same power supply mode can correspond to multiple operations. For example, the user needs to supply power to the camera during the camera operation and the video chat operation, and both the camera operation and the video chat operation correspond to the power supply of the camera.

The setting saving module 30 is configured to save the setting of each register corresponding to the power management chip of the mobile terminal in various power supply modes. For the setting of each register corresponding to various power supply modes saved in the setting saving module 30, the setting of a register corresponding to a power supply mode is the default value of the register after the power management chip is reset, that is, the default value of the register after the power management chip is reset The default power supply mode is one of various power supply modes stored in the memory, so as to ensure that the power management chip can still work normally after the power management chip is reset.

Wherein, the setting saving module 30 is a memory, and the memory is a non-volatile memory after power failure, such as emmc, flash, eeprom and the like. Among them, the memory stores the settings of the corresponding registers in various power supply modes: power supply mode 1 corresponds to register setting 1, power supply mode 2 corresponds to register setting 2, power supply mode 3 corresponds to register setting 3, ..., power supply mode N corresponds to register Set N. Wherein, N is a natural number greater than or equal to 2.

The power supply setting module 10 is used when the power supply mode needs to be switched, according to the power supply mode to be switched to, obtains the register setting corresponding to the power supply mode in the power management chip; obtains the register setting corresponding to the current power supply mode in the power management chip ; Compare the register settings corresponding to the power supply mode to be switched to with the register settings corresponding to the current power supply mode, and obtain registers with different settings; only write the settings of the registers in the power supply mode to be switched to that are different from the current power supply mode settings into the power management In the corresponding register of the chip. Specifically, the power supply setting module 10 finds out the corresponding power supply mode from the operation association module 20 according to the operation command sent by the mobile terminal, the power supply mode is the power supply mode to be switched to, and the power supply mode to be switched to according to the need, Obtain the register setting corresponding to the power supply mode from the setting preservation module 30, and obtain the register setting of the current power supply mode; compare the register setting corresponding to the power supply mode to be switched to and the register setting corresponding to the current power supply mode, and obtain different registers; only Write the settings of the registers in the power supply mode to be switched to that are different from the current power supply mode settings into the corresponding registers of the power management chip. That is, the power supply setting module 10 compares the register settings corresponding to the two power supply modes, and after finding the registers with different settings, it only needs to change the settings of these registers with different settings to complete the switching of the power supply mode, which greatly reduces The number of registers that the power management chip needs to set when switching the power supply mode is reduced, thereby improving the efficiency of power supply mode switching and saving battery power.

Further, the power supply setting module 10 is also used to save the register settings corresponding to the current power supply mode in the power management chip after the power supply mode is switched, so that when the power supply mode is switched next time, the register corresponding to the power supply mode can be obtained directly. set up. Of course, the power supply setting module 10 can also be used to associate the operation instruction with setting different registers and their register settings after the power supply mode is switched, and save it. When the user sends the operation instruction through the mobile terminal next time, There is no need to obtain the register settings corresponding to the power supply mode to be switched to and the current power supply mode, and there is no need to compare the register settings of the two power supply modes, and directly write the register settings corresponding to the operation instruction into the corresponding registers of the power management chip. It can be seen that the steps of acquisition and comparison are further saved, and the efficiency of power supply mode switching is improved.

In the specific implementation, taking three power supply modes as an example, the registers corresponding to these three power supply modes are set as follows:

Power supply mode 1 of the power management chip:

register address register set 1 0x0101 0x22 0x0102 0x02 0x0103 0x55 0x0104 0x18 0x0105 0x61 0x0106 0x52 0x0107 0x22 0x0108 0x88

Power supply mode 2 of the power management chip:

register address Register Set 2 0x0101 0x72 0x0102 0x02 0x0103 0x55 0x0104 0x18 0x0105 0x68 0x0106 0x52 0x0107 0x22 0x0108 0x88

Power supply mode 3 of the power management chip:

register address Register Set 3 0x0101 0x82 0x0102 0x02 0x0103 0x55 0x0104 0x18 0x0105 0x68 0x0106 0x82 0x0107 0x22 0x0108 0x66

Assume that the current power supply mode of the power management chip is power supply mode 3, the user needs to switch the power supply mode 3 to power supply mode 2 when operating the mobile terminal, and set the operation command as operation 2, then the power supply setting module 10 compares the power supply mode 3 with the power supply mode 2. The register settings corresponding to mode 2, the registers to be set and their settings are obtained:

register address Register settings 0x0101 0x82 0x0106 0x82 0x0108 0x66

Therefore, just modify the setting of the register with address 0x0101 to 0x72, the setting of the register with address 0x0106 to 0x52, and the setting of the register with address 0x0108 to 0x88, and the transition from power supply mode 3 to power supply mode is completed. 2 switch. It can be seen that, in this example, only need to modify the three register settings to complete the switching of the power supply mode. In practical application, since the functions of mobile terminals are increasing, the power supply modes are also increasing, and the registers corresponding to the power supply modes are also increasing. Using the configuration method provided by the present invention can greatly reduce the modification of register settings, not only The switching efficiency of the power supply mode is improved, and the service life of the power management chip is also improved.

Moreover, since the power supply setting module 10 has saved the corresponding relationship between operation 2 and register 0x0101 and register setting 0x72, register 0x0106 and register setting 0x52, register 0x0108 and register setting 0x88, when the user performs operation 2 next time, the power supply setting module 10 directly sets The settings of register 0x0101, register 0x0106 and register 0x0108 of the power management chip can be modified, which saves the action of obtaining and comparing the register settings of the two power supply modes, and further improves the power supply efficiency.
