Description
Technical field
The present invention relates to field of mobile communication, particularly a kind of smart mobile phone is saved the method for the loss of power.
Background technology
Communication terminal moves in China and is widely used at present.Wherein, the mobile phone of representative products presents three main trend, and one, quantity is increasing, 2011, national mobile phone user broke through 900,000,000 families; Two, intellectuality, increasing mobile phone has been installed intelligent operating system; Three, screen is increasing.
Mobile phone can be divided into smart mobile phone and non intelligent mobile phone, and their advantages and deficiency are respectively:
Smart mobile phone possesses the repertoire of regular handset, can converse normally, and the mobile phone such as send short messages is used; The ability that possesses the wireless access the Internet is such as GPRS, 3G network, WIFI network insertion; Function with PDA is such as schedule account, task arrange, multimedia application, browsing page; Have open operating system, more application program can be installed, make the function of smart mobile phone can obtain infinite expanding; Powerful, scalability is strong, and the third party software support is many.But power consumption is serious, and hardware requirement is higher, and operation is comparatively complicated, poor stability, easily is subject to viral attack.
Non intelligent mobile phone, simple to operate easy-to-use, be easy to left-hand seat; Power consumption is little, and function is simple; The stability of a system is good; Can not be subject to virus harasses; But software extensions is poor; Operating experience is unalterable.
In addition, increasing when mobile phone screen, when intelligent degree was more and more higher, power consumption also significantly increased, and one of non intelligent function work of past is more than week, and the now smart mobile phone filled in one day one becomes inevitable problem.Smart mobile phone is short service time, has become one of the most serious problem of limited subscriber experience.
Summary of the invention
Purpose of the present invention overcomes the deficiencies in the prior art, propose a kind of smart mobile phone and save the method for the loss of power, it has merged the advantage of smart mobile phone and non intelligent mobile phone, and it can make the user be operated under the state of non intelligent machine, also can be operated under the state of intelligent machine simultaneously.
The present invention is achieved by the following scheme:
A kind of smart mobile phone is saved the method for the loss of power, it is characterized in that, described handset processes device provides an auxiliary processor core and one or more main processor core, during operating handset, may further comprise the steps:
Under the default conditions, the auxiliary processor core executive program of processor reads the start-up parameter of non intelligent system of the configuring area of Nand flash memory, starts and is operated in non intelligent system step;
When mobile phone need to be operated in intelligent environment lower time, the one or more main processor core work of described processor, and kernel executive reads the start-up parameter of intelligence system of the configuring area of Nand flash memory, starts and is operated in the intelligence system step;
System's switch step, the non intelligent system that auxiliary processor core executive program by described processor reads Nand flash memory switches to the start-up parameter of intelligence system, the primary processor that triggers processor goes to start intelligence system according to the start-up parameter of intelligence system, perhaps be used for main processor core executive program by described processor read Nand flash memory intelligence system switch to the start-up parameter of non intelligent system, the auxiliary processor that triggers processor goes to start non intelligent system according to the start-up parameter of non intelligent system.
As optimization, described mobile phone only has the auxiliary processor core of described processor in running order under non intelligent system environments; Mobile phone only has the main processor core of described processor in operating state under the intelligence system environment.
The present invention in sum has following distinguishing feature:
1. utilize this programme, the user can make smart mobile phone be operated in the state of non intelligent mobile phone, effectively solves the short problem of present intelligent machine stand-by time.
By auxiliary processor core and main processor core technological means, by the combination of non intelligent system and intelligence system, solving the mobile phone power consumption problem simultaneously, also solve non intelligent cell phone software autgmentability poor; The problem that operating experience is unalterable.
Description of drawings
Fig. 1 is the structural representation that the present invention relates to the processor of mobile phone;
Fig. 2 is the overall structure schematic diagram that the present invention relates to mobile phone.
Embodiment
Definition: non intelligent system is for only providing voice and SMS for communication terminal and guaranteeing the platform that basic display is exported, such as the S40 platform of Nokia, the MTK platform of Lian Fake, the A100 platform of Sony-Ericson, the P2K platform of Motorola etc.; Intelligence system is Saipan S60 operating system, windows mobile operating system or Android operating system etc.
Below in conjunction with accompanying drawing, embodiment of the present invention is described further:
With reference to figure 1, the processor of the mobile phone that the inventive method relates to is provided with an auxiliary processor core and one or more main processor core.Under the preferred version, auxiliary processor core quantity is 1, and the quantity of main processor core is 2 or 4.
Except processor, the mobile phone that the inventive method relates to comprises Nand flash memory, processor and the compositions such as communication module and display module.Wherein with reference to figure 2, Nand flash memory is provided with the first reading unit, the first start unit, the second reading unit, the second start unit, unit, public area and the start unit that intersects.Their functions and interrelationship are:
The first reading unit is used for the start-up parameter of non intelligent system that auxiliary processor core executive program by described processor reads the configuring area of Nand flash memory;
The second reading unit is used for the start-up parameter of intelligence system that main processor core executive program by described processor reads the configuring area of Nand flash memory;
The first start unit, the auxiliary processor core that is used for by described processor starts non intelligent system according to the start-up parameter of the non intelligent system of described the first reading unit;
The second start unit is used for main processor core by described processor according to the start-up parameter startup intelligence system of the intelligence system of described the second reading unit;
The unit, public area is used for being stored in the start-up parameter that switches to intelligence system under the non intelligent system environments and the start-up parameter that switches to non intelligent system under the intelligence system environment;
The intersection start unit, be used for the start-up parameter that non intelligent system that auxiliary processor core executive program by described processor reads the unit, public area of Nand flash memory switches to intelligence system, the primary processor that triggers processor goes to start intelligence system according to the start-up parameter of intelligence system, perhaps be used for the start-up parameter that intelligence system that main processor core executive program by described processor reads the unit, public area of Nand flash memory switches to non intelligent system, the auxiliary processor that triggers processor goes to start non intelligent system according to the start-up parameter of non intelligent system.
