Public and financial business, one is used for daily online and life ＆ amusement, and the use of plurality of mobile phones brings very big for life and trip
It is inconvenient.Current mobile phone terminal also has using double-core CPU, and the modes of dual processors or dual operating systems realizes that same portion is held
Isolation in terminal not only meets the needs of users but also is convenient for carrying use, but since hardware support kit especially memory etc. is shared,
Networking software can not be actually effectively prevented to steal trade secret and privacy of user, ensure handheld terminal operating system
Safety.
Invention content
For solve it is above-mentioned in the prior art the defects of, the present invention provides a kind of safe handheld terminal charge and discharge device and
Method.
The purpose of the present invention is achieved through the following technical solutions a kind of dual processors physically-isolated handheld terminal entirely, including
CPU1, CPU2, operating system 1, operating system 2, internal storage location 1, internal storage location 2, switch control unit, power control circuit,
Battery and load sharing, CPU1, operating system 1 and internal storage location 1 form system 1, CPU2, operating system 2 and internal storage location 2
Composition system 2, system 1 and system 2 are set independently of each other, and carry out data exchange by load sharing and peripheral hardware；The behaviour
Make system 1 to operate on CPU1, CPU1 is connected with internal storage location 1；Operating system 2 is operated on CPU2, CPU2 and internal storage location 2
It is connected；A switching command acquisition module is further included, is connected with the input terminal of switch control unit, the output terminal of switch control unit
It is connected with power control circuit, battery.
Wherein, the switching command acquisition module is connected with the button of corresponding key assignments defined in kernel, works as behaviour
When making the operation of system 1, CPU1 is in wake-up states, and CPU2 is in a dormant state；When a key is pressed, system detectio to button simultaneously
Corresponding key assignments, CPU1 notice switch control units are reported, switch unit control power control circuit is powered to CPU2, CPU2
Into wake-up states, CPU1 enters dormant state；When operating system 2 brings into operation at this time, when a key is pressed, system detectio arrives
Button simultaneously reports corresponding key assignments, CPU2 notice switch control units, and switch unit control power control circuit is supplied to CPU1
Electricity, CPU1 enter wake-up states, and CPU2 enters dormant state.
Preferentially, the load sharing includes at least display screen, touch screen, button, USB interface, network interface, the hands such as GPIO mouthfuls
Machine common hardware interface.
Compared with prior art, the invention has the advantages that：
1) using dual-CPU architecture, two sets of completely self-contained systems is run, meets user demand and is convenient for carrying use；
2) each CPU possesses independent internal storage location, to complete the read-write of the data of respective operations system, realizes complete
Physical isolation, really prevents networking software and trade secret and privacy of user is stolen；
3) single system operation is realized to the power supply control of dual processors by switch control unit and power control circuit completion
When correspond to CPU wake-up and another CPU suspend mode, realize dual processors dual system low power operation；
4) dual processors share the non-critical loads such as USB interface, network interface, display screen, touch screen and peripheral hardware, reduce hardware spending.
Description of the drawings
Fig. 1 is the system schematic of the embodiment of the present invention.
Fig. 2 is dual system handoff relation figure in the embodiment of the present invention.
Specific embodiment
With reference to specific embodiment, the present invention is described in detail.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill to this field
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection domain.
As shown in Figure 1, an embodiment of the present invention provides a kind of dual processors physically-isolated handheld terminal entirely, including two solely
Vertical CPU1 and CPU2, two independent internal storage locations 1 and internal storage location 2 will not generate data exchange between two memories, and two
A independent CPU can not also read the memory of other side；Operating system 1 is operated on CPU1, and CPU1 is connected with internal storage location 1；Behaviour
Make system 2 to operate on CPU2, CPU2 is connected with internal storage location 2；Display screen, touch screen, button, USB interface, network interface, GPIO
The mobile phones universals hardware interfaces such as mouth are load sharing, and it is real that two independent CPU can pass through these shared non-critical loads
