In the present embodiment, as shown in Fig. 2 logical by USB between the first application processor 10 and the second application processor 20
Letter, usb communication uses the design of two lines：TX (transmission) and RX (reception).In order to ensure double LTE communication function, first should
Running status is constantly in the application processor 20 of processor 10 and second, when there are data to need transmission, directly invokes TX's
Driving interface sends data.The multiple subsystems of RPM13 management and control of mobile terminal 1 00, there is the first application processor 10, first respectively
Modem 11, PRONTO (WIFI bluetooth, NFC etc.), LPASS (Low power audio subsystem, low-power consumption sound
Frequency subsystem), when the first application processor 10 and the second application processor 20 are in running status, the clock used on USB
Resource (clk1, clk2) is occupied always and can not discharge, and causes the first application processor 10 and the nothing of the second application processor 20
Method enters resting state, although RPM resting state is chosen in a vote by subsystems, as long as but the first application processing
The application processor 20 of device 10 and second is without dormancy, and application processor is that can throw the poll for opposing dormancy so that whole system is equal
Can not dormancy, so as to cause the whole mobile terminal 1 00 all can not dormancy.So, the power consumption of mobile terminal is caused to occupy height always not
Under, so as to reduce Consumer's Experience.
Further, the serial ports includes USB serial ports, and the application processor 20 of the first application processor 10 and second leads to
Cross the connection of USB serial ports.Have on first application processor 10 on first clock sources, second application processor 20 and have
Body second clock resource, when the application processor 20 of first application processor 10 and second is in running order, the USB
Serial ports takes first clock sources and/or second clock resource；At the application of the first application processor 10 and second
When managing device 20 in a dormant state, the USB serial ports discharges first clock sources and/or second clock resource.
The controller is used to obtain between the first application processor 10 of mobile terminal 1 00 and the second application processor 20
Serial ports on data transmission state, if detecting the data transmission state within the scheduled time such as 500ms on USB serial ports
No data is transmitted, then discharges the clock sources on the serial ports, and controls when meeting preparatory condition the first application processor 10
Enter dormancy with the second application processor 20.
Whether there is the specific testing mechanism of data transfer as follows on serial ports：
Resource requirement is reported that RPM13 is according to each subsystem to resource to RPM13 by each subsystem of mobile terminal 1 00
Demand carries out comprehensive assessment, it is determined that the device for the consumption energy that can be closed and open, and perform corresponding control.Specifically
Ground, between the first application processor 10 and the second application processor 20 of dormancy control system, mainly carries out two by USB serial ports
Wake-up, state notifying and usb communication between individual application processor.
By carrying out data transmit-receive state to the USB serial ports between the first application processor 10 and the second application processor 20
Detection, if within the scheduled time such as 500ms, being not detected by data, then show that in 500ms no data is transmitted on USB serial ports,
At this point it is possible to discharge the first application processor 10 and the second application processor 20 on USB serial ports clock sources (clk1 and
Clk2), so that RPM13 enters resting state by arbitration mechanism control.Clock on USB serial ports is for keeping data
Time during front and rear synchronous, the control dormancy awakening of transmission is precisely and synchronous with the clock holding of system, included in string
Mouth driving layer operation.
Further, the USB serial port drives of the first application processor 10 and the second application processor 20, with control data
The function of transmitting-receiving.When needing transceiving data, calling corresponding function interface, namely detect the presence of data transmit-receive only needs inspection
Survey the function interface whether called within a predetermined period of time.And the first application processor 10 and the second application processor 20
Detection operation can be performed because two application processors be required to determine by this testing mechanism itself whether the progress
Dormancy.
USB serial ports between first application processor 10 and the second application processor 20 is defined by Serial Port Transmission agreement
Serial ports dormancy mechanism, the dormancy function that the Serial Port Transmission agreement is carried such as USB_POWER_DOWN () function, supports that itself stops
Sleep.If detecting no data transmission (function interface is not called upon) within the scheduled time such as 500ms, Serial Port Transmission agreement is called
The dormancy function carried such as USB_POWER_DOWN () function, it is that the resource discharged shared by serial ports includes to perform serial ports dormancy
Clock sources, now, corresponding modem could carry out dormancy.
It is the serial port drive of the first application processor 10 because clk1 is corresponding, clk2 corresponding is the second application processor
20 serial port drive, then, clk1 do not discharge can cause the first application processor 10 can not dormancy, clk2, which does not discharge, can cause
Two application processors 20 can not dormancy.Therefore, the control dormancy between the first application processor 10 and the second application processor 20
It is separate, not by other side's control, it is not required that other side votes, as long as above-mentioned condition is met, then performs respective
Dormancy control program.
Specific dormancy control sequence can be scheme as described below：
Because RPM13 controls four subsystems (application processor, modem, PRONTO and LPASS) resource,
All subsystems need to be applied to RPM13 when needing to use resource, then.Therefore, subsystems are not needing work
When, that is, the dormancy program of itself is performed, oneself dormancy is said to RPM13 ballots after subsystem dormancy.When four subsystems to
RPM13 has been thrown after dormancy ticket as above, and host CPU is closed in RPM13 decision-makings, while itself also dormancy, now whole system is into most
Low-power consumption.That is, dormancy control system is when control carries out dormancy program, modules enter the sequencing of dormancy successively
It is：Four subsystems, RPM13, CPU.It is understood that the above-mentioned scheduled time is not limited to the tool enumerated in the present embodiment
Body numerical value, can according to actual needs such as size parameter of the shapes and sizes of dormancy control system, data card and for changing

Dormancy control program.
Specific dormancy control sequence can be scheme as described below：
Because RPM13 controls four subsystems (application processor, modem, PRONTO and LPASS) resource,
All subsystems need to be applied to RPM13 when needing to use resource, then.Therefore, subsystems are not needing work
When, that is, the dormancy program of itself is performed, oneself dormancy is said to RPM13 ballots after subsystem dormancy.When four subsystems to
RPM13 has been thrown after dormancy ticket as above, and host CPU is closed in RPM13 decision-makings, while itself also dormancy, now whole system is into most
Low-power consumption.That is, dormancy control system is when control carries out dormancy program, modules enter the sequencing of dormancy successively
It is：Four subsystems, RPM13, CPU.
It should be understood that due to being separate between the first application processor 12 and the second application processor 22
, not by other side's control, therefore, detecting between the first application processor 12 and the second application processor 22
