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 embodiment in the application and the feature in embodiment can combine mutually.
As shown in Figure 1, the invention provides a kind of electronic installation 1, described electronic installation 1 can be embedded electronic device 1, such as mobile phone, panel computer, router etc., runs and has embedded OS, as Linux etc.; Described electronic installation 1 comprises: at least two storage unit 11, are connected to bidirectional bus chip 12, and namely described bidirectional bus chip 12 realizes the data bus between processor 14 to each storage unit 11; Processor 14 (such as MCU, SoC chip etc.), is connected to each storage unit 11 by each described bidirectional bus chip 12, during for occurring damaging in used storage unit 11, switching other storage unit 11 and carrying out work; At least two gauge tap 13, be connected with correspondingly and be connected to each described bidirectional bus chip 12, respectively at least for controlling the on-off of each storage unit 11 power supply, described gauge tap 13 realizes by the integrated chip of the switching device such as field effect transistor, triode and those devices.
It should be noted that, although in the illustrated embodiment in which, the storage unit 11 of showing, bidirectional bus chip 12 and gauge tap 13 are only two groups, in fact can be greater than two groups, are not limited with the present embodiment.
In one embodiment, described storage unit 11 stores the data message for reading for described processor 14, such as, start the log-on message of described electronic installation 1; Described storage unit 11 comprises flash connector and the pluggable flash memory (Flash) being connected to described flash connector.
In one embodiment, about the judgement that described storage unit 11 is damaged, for example, when in electronic installation 1 operational process to storage unit 11 have write or read action time, if write or read unsuccessfully, storage unit 11 can be judged to and damage, preferably, electronic installation 1 sends alarm information noticing user by modes such as such as display, sound, and user can change the storage unit 11 damaged according to this warning information.
Described electronic installation 1 also comprises: internal storage location 15 (such as RAM etc.), be connected to described processor 14, for running the data message that described processor 14 reads from described storage unit 11, concrete, after powering on, processor 14 is given tacit consent to and is obtained data message from one of them storage unit 11 and be mapped to internal storage location 15, if the log-on message of the storage unit used 11 is damaged or is lost, processor 14 can jump to another storage unit 11 automatically to be carried out obtaining information and ensures that namely system normal startup optimization realizes active-standby switch, and export the warning information of storage unit 11 damage, system startup optimization preprocessor 14 by all such as system data and configuration information all mirror image be loaded in internal storage location 15 run, also can have read-write motion to storage unit 11 in described system operation, and except system requirements read-write operation, storage unit 11 all can be in idle condition.
In one embodiment, described gauge tap 13, when damaging appears in the bidirectional bus chip 12 corresponding stored unit 11 for connecting at it, disconnects the power supply of the storage unit 11 damaged; Further, described gauge tap 13, when damaging appears in the storage unit 11 of bidirectional bus chip 12 correspondence also for connecting at it, at least control linkage makes the bidirectional bus at its place be in high-impedance state, so that user carries out the replacing of storage unit 11 in the bidirectional bus chip 12 of the storage unit 11 damaged.
Concrete principles illustrated is as follows, because the operating system cannot run powering under normal circumstances carries out changing the operation of device, especially storage unit 11 (such as loading the Flash of log-on message) this Primary Component, interruption or the collapse of electronic installation 1 built-in type system cloud gray model can be caused, so substitute mode of the present invention seems particularly crucial, when storage unit 11 is damaged, storage unit 11 power outage of corresponding unit is made by controlling gauge tap 13, and be all placed in high-impedance state to the data bus of the corresponding connection of the storage unit 11 that major general is all with to be replaced, to avoid the latch-up causing circuit chips in operating process, the data bus and the power bus that it should be noted that this storage unit 11 can be roads, may not be a road, and the present invention is different from the mounting means of traditional direct welding Flash, uses the mounting means can changing flash memory neatly of plug type, described gauge tap 13 can be enable for closure state is to realize the normal work of corresponding storage unit 11, not enable to it, the state of being off is carried out storage unit 11 and is changed, such as in actual Renewal process, after gauge tap 13 is in off-state, namely realize aforementioned to stop power supply and setting data bus is high-impedance state.Directly take off flash memory from flash connector, and be installed in flash connector by new flash memory, then enable gauge tap 13 is closure state, namely recovers storage unit 11 normal power supply and data bus cancellation high-impedance state.
So, when only being stopped power supply in local in the not power-off of whole electronic installation 1, the storage unit 11 of damage can be replaced by online a new storage unit 11, very convenient; Preferred, after replacing, data in the internal storage location 15 of whole embedded system just in operational process are controlled to be written to online in the new storage unit 11 after replacing by processor 14, therefore without the need to manpower manual, the storage unit 11 changed is carried out to the burning action of program, just can realize to new storage unit 11 at line writing, and the data of institute's programming are with the data syn-chronization run of current system.
In sum, the invention provides a kind of electronic installation, comprising: at least two storage unit, be connected to bidirectional bus chip; Processor, is connected to each storage unit by each described bidirectional bus chip, during for occurring damaging in used storage unit, switching other storage unit and carrying out work; At least two gauge tap, are connected with correspondingly and are connected to each described bidirectional bus chip, respectively at least for controlling the on-off that each storage unit is powered; Thus when storage unit is damaged, can be stopped power supply to the storage unit damaged by gauge tap and change, and to whole electronic device after current failure, the problem that in prior art, storage unit need be changed need not be solved.
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 bent technical field 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.
