Embodiment
Compare with existing memory device, memory device in the present invention is that multi storage is combined, multi storage is controlled by Programmable Logic Controller is unified, bring into play different storage mediums in protocol layer, application layer characteristics, can be at any time that some are novel application function joins in certain medium in memory device, to reach the purpose of expanding storage apparatus application function.
In the present invention, main frame carries out communication by general-purpose interface and memory device, memory device comprises general-purpose interface, controller and multi storage, and storage medium can be flash memory, hard disk or random access memory (Radom Access Memory, RAM) etc.Various storage medium unifications are controlled by controller, and from the main frame to the memory block, controller is realized its control function as bridge (Bridge) on data link.
Store application program on certain or some storage mediums in memory device, when memory device is connected to main frame, under the control of controller, utilize the Disk Mapping technology, the storage medium of preserving application program is mapped on main frame, runs application on main frame.
The below introduces embodiments of the invention, and the method that realizes the expanding storage apparatus function is described in detail.
Referring to Fig. 1, embodiment comprises:
Step 101: controller is set multi storage is unified to connect and control;
Wherein, controller adopts Programmable Logic Controller, 8051 single-chip microcomputers for example, perhaps ARM (AdvancedRISC Machines) etc.; In the present invention, the storage medium kind is incessantly a kind of, comprises the various storage mediums of at present existing and following appearance, for example, and FLASH, HDD or RAM etc.
Controller is realized unified control to multi storage, can adopt multiplexing mode, and for example, FLASH and HDD adopt time-sharing multiplex, the data bus of shared control unit; Perhaps controller has the interface of the different storage mediums of access, also can realize the unified of multi storage controlled.
Step 102: multi storage is carried out subregion;
Wherein, various storage medium subregions are arranged sequentially, and for example, FLASH and HDD subregion are arranged sequentially, wherein wish preserved the storage medium subregion of application program front, the FLASH subregion for example are set front.
Step 103: with application storage in storage medium;
The application program here comprises and the multiple application program of existing and following appearance can realize multiple application function by these application programs, and for example, multi partition, subzone hiding, data encryption, speed are controlled, automatically scouted and mobile office etc.
Wherein, can on production line just with some application storage on certain or some storage medium, preferably, also can add at any time when the user uses.
The latter's implementation method can adopt prior art, for example, utilizes the platform of operating system that application program and memory device are connected.Specifically, by the operating system on main frame, with the form of read/write function, with the general-purpose interface of application program by memory device, under the control of controller, write in storage medium, such as being written in FLASH.
Wherein, general-purpose interface comprises the interface of existing or future appearance, such as USB interface, serial ports or parallel port etc.
Step 104: memory device and main frame are connected;
Step 105: the storage medium that will preserve application program is mapped on main frame;
The realization of this step is automatically to complete under the control of controller, utilizes the Disk Mapping technology, can set in advance the address that is mapped to main frame.
Preferably, with preserving the CDROM mode of storage medium (FLASH) partition map of application program to main frame, like this, just can take full advantage of the automatic operation characteristic of CDROM, application program on FLASH is moved on main frame automatically, user-friendly.
Perhaps, also can be with storage medium (FLASH) partition map of the preserving application program zone except CDROM to the main frame, for example D dish.In this case, can perhaps be controlled by controller simultaneously preserving storage AUTORUN program on the storage medium of application program (FLASH) subregion, be able to operation automatically on main frame.Perhaps, run application in the mapping area click by the user.
Step 106: run application on main frame;
When being mapped to the CDROM mode, with memory device with after main frame is connected, the application program that memory device is preserved is operation automatically.
Step 107: the disconnection memory device is connected with main frame, simultaneously, and main frame Self-tipping application program.
After completing the use of memory device, main frame can fall application program by Self-tipping, does not affect other operations on main frame.
As seen, the present invention combines multi storage, takes full advantage of the characteristics of various storage mediums, has realized the expansion to storage apparatus application function.Method of the present invention realizes simple, particularly in preferred version, utilizes the characteristic of CDROM with application program operation automatically on main frame, and it is very convenient that the user feels.
The present invention also provides a kind of memory device, and this memory device can be realized the application function that enriches, and easy to use.
As shown in Figure 2, be connected the use schematic diagram with memory device 202 for main frame 201.
Wherein general-purpose interface 211 can be the various interface of existing or following appearance, such as USB interface, serial ports or parallel port etc.General-purpose interface 211 is mainly used to connect the communication between main frame 201 and memory device 202, comprises the data that receive from main frame 201, sends to controller 212, perhaps receive controller 212 data, send to main frame 201.
Storage medium is the core of memory device 202, and major function is the storage data.Storage medium of the present invention comprises a plurality of kinds, comprises the various storage mediums of existing or future appearance.By the unified Selective storage media storage application program of controlling of controller 212, for example, store application program on flash memory 213.
As seen, memory device 202 provided by the invention is comprised of multi storage, and simultaneously, all storage mediums are all worked under unified control of controller 212.Especially, utilize the characteristics of some storage medium (for example FLASH), with its subregion front, and with application storage in this storage medium; When memory device 202 being connected use with main frame 201, controller 212 is mapped to subregion certain zone of main frame 201 at front, as to preserve application program storage medium (FLASH), CDROM for example, automatically run application on main frame, realized the purpose of expanding storage apparatus 202 application functions.
The above is only the preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
