Below will cooperate graphic and embodiment specifies embodiment of the present invention, whereby to the present invention how the application technology means implementation procedure that solves the problem of the storage area that can't properly utilize the outer storage area of main storage device in the same electronic equipment to expand main storage device and reach the technological effect that improves the storage area availability can make much of and implement according to this.
Define to term of the present invention at first, earlier.
Storage area of the present invention virtual method is applicable in the operating system that electronic equipment moved with main storage device and at least one expansion storage device.What need special instruction is can be desktop computer, notebook computer, portable electric device or other electronic equipments that expansion storage device can be installed and carry out operating system in electronic equipment of the present invention.In addition, all can be IDE hard disk, SATA hard disk, the USB mobile memory that comprises flash memory (flashmemory), various storage card in main storage device of the present invention and expansion storage device ... any storage device in waiting.In addition, storage device also can be that the difference of same storage device is cut apart, as: the C dish of same hard disk and D dish also can be considered different storing devices.The difference of main storage device and expansion storage device only is equipped with storage device and other general storage devices that stores functions of operating system in order to explanation.For instance; Suppose to be equipped with in the PC hard disk and assigned a USB storage device, if operating system is installed in the hard disk, then hard disk is main storage device; The USB storage device is then for expanding storage device; If this hard disk is cut apart C dish and D dish are arranged, and operating system is installed in the C dish, then D dish and USB storage device all are regarded as expanding storage device.
Next, please refer to Fig. 1, be the process flow diagram of storage area of the present invention virtual method, will be in order to implementing procedure of the present invention to be described.Storage area of the present invention virtual method is after the operating system of electronic equipment operation receives the virtual request that starts virtual main storage device stores space, to begin to such an extent that move; The producing method of virtual request; Can the person of being to use pass through that input system instruction back produces; Also can be that operating system detects in the main storage device storage area and produces automatically when not enough, then not limit to producing method of virtual request at this.
At first, receive the virtual request (step 101) that starts virtual main storage device stores space when the operation system after, at first be received from choose at least one expansion storage device wherein one expand storage device (step 102).When a plurality of expansion storage device is installed in the electronic equipment; Operating system can read the residue storage area value of all expansion storage devices in the electronic equipment earlier; And show that the residue storage area non-vanishing expansion storage device of value supplies the user to choose; After choosing in the expansion storage device that the user shows certainly, operating system will be carried out follow-up storage area pseudo operation in the expansion storage device of choosing.In addition, when the residue storage area of all expansion storage devices value all was zero, this moment, operating system can show that the full prompting in a space can't carry out the pseudo operation of storage area at present with the prompting user.When if single expansion storage device only is installed in the middle of the electronic equipment; Operating system can read the residue storage area value that expands storage device equally; When residue storage area value is non-vanishing; Then directly with only expansion storage device as the expansion storage device of choosing, if residue storage area value is zero, can show equally that then the full prompting in a space can't carry out the pseudo operation of storage area at present to point out the user.
After operating system receives the expansion storage device of choosing, then calculate the zone of reasonableness (step 103) of required storage area value according to the residue storage area value of the value of taking up room of the required configuration file of the virtual process of carrying out main storage device stores space and the expansion storage device chosen.Configuration file; Refer to the archives of the address configuration in the time of can being used for writing down virtual storage area; Since parameter value that address configuration write down like: start and end physical storage address, store character value ... wait numeral or character data to store, so the value of taking up room of configuration file can be calculated in advance by operating system with fixing character.Operating system then will calculate the zone of reasonableness of required storage area according to the residue storage area value of the value of taking up room of configuration file and the expansion storage device of choosing.For instance; After the value of taking up room of configuration file of a 4KB has been deducted in the residue storage area of supposing 2GB; The zone of reasonableness that can draw required storage area value is 0～1.996GB; Then operating system will be in setting the interface display zone of reasonableness, and receive the required storage area value (step 104) that the user chooses in zone of reasonableness.And, can be a literal inputting interface that is available for users to direct input value, or be available for users in a plurality of options, choose the menu operation interface of setting at the setting interface of this indication.
After the operation system receives required storage area value; Then set up configuration file (step 105) in expanding storage device; And the address configuration in first storage area, second storage area and main storage device stores space is recorded in (step 106) in the configuration file; Wherein, first storage area is to dispose gained according to required storage area value in expanding storage device, and second storage area is for expanding the storage area that storage device is not configured to first storage area and does not comprise configuration file.Described configuration file; The initial storage address that can the end in main storage device stores space be stored the address and first storage area stores; So that during the storage address of layout first storage area; The end that operating system can continue main storage device stores space stores the address and continues layout, makes the formatting of in fact identical with the storage address tool in main storage device stores space and the continuity in first storage area.In addition; Because first storage area and second storage area are actually the storage area of same expansion storage device; And first storage area will be regarded as the storage area of main storage device after virtual completion; Therefore interfere with each other for the storage area management of avoiding first storage area and second storage area; The configuration of second storage area also can be stored simultaneously, make virtual first storage area afterwards will carry out the accessing operation of main storage device, and the original accessing operation that expands storage device will be carried out in second storage area.
What need special instruction is; When setting up configuration file; The user's access right that can set configuration file is read-only, and only allows that content that operating system is directed against configuration file carries out the operation of read and write, and the person of avoiding the use of alters configuration file arbitrarily and makes System Operation produce gross error.
Operating system will restart (step 107) after address configuration is recorded in configuration file; And read configuration file and combine first storage area as main storage area, the virtual back of electronic equipment with main storage device stores space, carry out data access operation (step 108) and expand the storage area as the virtual back of electronic equipment with second storage area.
Except above-mentioned step; When the operation system receives the data access operation of a reading and writing of files; Operating system will be recorded in the file information of the access program of the file path that comprises reading and writing of files at least, file correspondence and file storage address in the configuration file; Whereby; When the operation system receive with expand storage device from electronic equipment remove remove request the time can read configuration file, and point out the user to remove to expand behind the storage device with affected access program and reading and writing of files by output change caution.In addition, remove when reinstalling to electronic equipment again when expanding storage device, operating system also can be carried out the data checking routine and whether expand data that storage device removes first storage area, back through revising with comparison.
Next; Please refer to Fig. 2, will with the portable electric device that possesses this machine storage device 210 and SD Card 220 200 as how an application have operating system of the present invention that the storage area is carried out virtual process detailed embodiment of the present invention to be described as embodiment.

After supposing to use operating system the present invention is arranged and run on portable electric device 200 and receiving the virtual request that starts virtual machine storage device 210 storage areas at present; Operating system will read the residue storage area value of SDCard 220; When if the residue storage area value of SD Card 220 is zero; Can export the full prompting in a space, point out the user can't carry out the pseudo operation of storage area at present whereby; Otherwise, when SD Card 220 residue storage area values are non-vanishing, then with SD Card 220 as the expansion storage device that will bring virtual machine storage device 210 storage areas.
Then, operating system will be calculated the zone of reasonableness of required storage area value according to the residue storage area value of the value of taking up room of the required configuration file of the virtual process of carrying out this machine storage device 210 storage areas and SD Card 220.For instance; Meaning as shown in Figure 3; Suppose to mark off in the SD Card storage area 221 residue storage area 222 and used storage area 223; Learn after then operating system reads after the sizes values of residue storage area 222, will calculate a zone of reasonableness according to the value of taking up room and the residue storage area value of configuration file.For instance; Suppose the configuration file of the 4KB of storage area needs of a 2GB of configuration in SD Card; Then when residue storage area value is 2.004GB, will produce the zone of reasonableness of a 0～2GB, this zone of reasonableness will be outputed to set subsequently supplies the user to choose required storage area value in the interface; And set the interface can the person of being to use the direct literal inputting interface of input value, or the user can choose the menu operation interface of setting in a plurality of options.What need special instruction is; Since parameter value that address configuration write down like: start and end physical storage address, store character value ... wait numeral or character data to store, so the value of taking up room of configuration file can be calculated in advance by operating system with fixing character.In addition; Since the value of taking up room of configuration file maybe be according to the data formats setting of various configuration rules and address configuration difference to some extent; Limit in this actual computation method that then is not directed against the value of taking up room of configuration file; The value of taking up room of the configuration file of therefore being given an example is only in order to the producing method of explanation zone of reasonableness, but not in fact calculates the mode of the value of taking up room of configuration file in order to qualification.
Please refer to Fig. 4; After the operation system receives required storage area value; Then will in the middle of SD Card, set up configuration file 224; And in SD Card, dispose one first storage area 226 according to required storage area value; And be second storage area with the storage area 223 and 225 that is not configured to first storage area 226 and does not comprise configuration file 224, the address configuration with first storage area 226 among this machine storage device and the SD Card and second storage area 223 and 225 is recorded in the configuration file 224 then, then restarts operating system.When setting up configuration file 224, the user's access right that can set configuration file 224 is read-only, and only allows that content that operating system is directed against configuration file carries out the operation of read and write.
At last; Operating system reads configuration file and combines virtual back this machine storage device stores space 231 of first storage area 226 as electronic equipment with this machine storage device stores space 221; Operate and carry out data access as the SD Card storage area, virtual back 232 of electronic equipment with second storage area 223 and 225; As shown in Figure 5; In the future any data that is stored in first storage area 226 will be regarded as in this machine of being stored in storage device, and the path of supposing this machine storage device is " .../root/ ", and the data that then is stored in first storage area 226 also can be under " .../root/ " path.
In addition; When the operation system received the data access operation of a certain reading and writing of files, operating system will be recorded in the file information of the access program of the file path that comprises this reading and writing of files at least, file correspondence and file storage address in the configuration file 224.For example: during the program data of a browser of access, the file that program data is read file name and the program data of file path, browser stores the address and all will be recorded in the configuration file 224.Whereby; When the operation system receives SD Card 220 is removed request and the time can read configuration file 224 from what portable electric device 200 removed, and point out the user to remove behind the SD Card 220 affected access program and reading and writing of files by output change caution.In addition, when SD Card 220 removes when reinstalling to portable electric device 200 again, whether operating system also can carry out data that the data checking routine removes first storage area 226, back with comparison SD Card 220 through revising.
Though the disclosed embodiment of the present invention is as above, be described content be not in order to direct qualification scope of patent protection of the present invention.Those of ordinary skill in the technical field under any the present invention under the prerequisite that does not break away from disclosed spirit of the present invention and scope, can be done a little change what implement in form and on the details.Scope of patent protection of the present invention, still must with appending claims the person of being defined be as the criterion.
