Embodiment
Below by way of specific instantiation, embodiments of the present invention are described, those skilled in the art the content disclosed by this instructions can understand other advantages of the present invention and effect easily.The present invention can also be implemented or be applied by embodiments different in addition, and the every details in this instructions also can based on different viewpoints and application, carries out various modification or change not deviating under spirit of the present invention.It should be noted that, when not conflicting, the feature in following examples and embodiment can combine mutually.
It should be noted that, the diagram provided in following examples only illustrates basic conception of the present invention in a schematic way, then only the assembly relevant with the present invention is shown in diagram but not component count, shape and size when implementing according to reality is drawn, it is actual when implementing, and the kenel of each assembly, quantity and ratio can be a kind of change arbitrarily, and its assembly layout kenel also may be more complicated.
Refer to Fig. 1, be shown as a kind of electronic equipment of the present invention modular structure schematic diagram in one embodiment.Described electronic equipment 1 comprises central processing unit 11, internal storage 12, system bus 13 and SD card 14, described internal storage 12 is such as flash storer or RAM etc., described internal storage 12 and described SD card 14 are electrically connected with described central processing unit 11 by described system bus 13, described system bus 13 is such as PC bus, AT-bus (isa bus), or the one in pci bus, comprise data bus DB (Data Bus), address bus AB (Address Bus) and control bus CB (Control Bus), be used for connecting each functional part of electronic equipment 1 and to make described electronic equipment 1 be formed a complete microsystem.
The system file district 121 of described electronic equipment 1 is arranged at described internal storage 12, described system file is read according to the first operational order to make described central processing unit 11, such as described central processing unit 11 is according to system initialization instructions, reloads described system file to carry out initialization.What store in described system file district 1 is read-only system file, the operating system such as adopted for described electronic equipment 1 or other firmware.And, in the present embodiment, the system data area 141 of described electronic equipment 1 and user data area 142 are arranged at described SD card 14, carry out read or write to make described central processing unit 11 according to the second operational order to the system data area 141 of described SD card and user data area 142.The image such as using described electronic equipment 1 to take for user stored in described user data area 142 or the audio-frequency information of admission, the information generated for the application software of described electronic equipment 1 loading stored in described built-in system data field 141 is such as the chat record of micro-letter or qq software or the pictorial information etc. of transmission or reception.
The operating system loaded for described electronic equipment 1 is for android system, the electronic equipment of current use android system only has the data subregion (sdcard subregion is virtual by fuse) of 1 physics, memory system data district and user data area in described data subregion, as long as namely described data subregion is arranged on the SD card of described electronic equipment 1, with the operation making the central processing unit 11 of described electronic equipment 1 read or write the built-in system data field 141 of described SD card and external user data district 142 according to an operational order.And due in android system, cannot run if data district does not exist system, so remove described SD card 14 when described electronic equipment 1 uses, described electronic equipment 1 must crash, and easily causes damage to file system.In described the present embodiment, described electronic equipment 1 also has a fixed sturcture, and in order to fixing described SD card 14, and only when the battery of described electronic equipment 1 is removed, described fixed sturcture just makes described SD card 14 be in the state that can be removed.Although electronic equipment 1 of the present invention adds the cost of a SD card because being equipped with SD card 14, but thus electronic equipment can adopt the less flash storer of capacity or ROM to deposit read-only system file, and the cost of electronic equipment still reduces generally.
The invention solves in prior art when electronic equipment damage and can not work time, user can not obtain and can not remove the data of built-in system data field and cause the problem using inconvenience and information easily to reveal, by the system file district of described electronic equipment is arranged at described internal storage, and the system data area of described electronic equipment and user data area are arranged at described SD card, read or write can be carried out according to operational order to the built-in system data field of described SD card and external user data district to make described central processing unit, make electronic equipment after damaged, user still can obtain or the data of scavenge system data field, be user-friendly to and ensure that user's sensitive data is not revealed.
In one embodiment, the invention allows for a kind of data processing method, main application electronic equipment 1 as described in Figure 1 carries out the process of data, so that the system file district of described electronic equipment is arranged at described internal storage, and the system data area of described electronic equipment and user data area are arranged at described SD card, read or write can be carried out according to operational order to the built-in system data field of described SD card and external user data district to make described central processing unit, make electronic equipment after damaged, user still can obtain or the data of scavenge system data field, be user-friendly to and ensure that user's sensitive data is not revealed.
In sum, a kind of electronic equipment of the present invention, a kind of SD card, and a kind of data processing method, the system file district of described electronic equipment is arranged at described internal storage, and the system data area of described electronic equipment and user data area are arranged at described SD card, read or write can be carried out according to operational order to the built-in system data field of described SD card and external user data district to make described central processing unit, make electronic equipment damaged and after can not starting shooting, user still can obtain or the data of scavenge system data field, be user-friendly to and ensure that user's sensitive data is not revealed.So the present invention effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all without prejudice under spirit of the present invention and category, can modify above-described embodiment or changes.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
