Conception of the present invention, be that the non-volatile memory storage in the data memory device is planned to the structure that includes unusual fluctuation data memory device and edition data storage device, the edition data storage device is used for storing user's supplemental characteristic, and the unusual fluctuation data memory device then is used for storing the modification part of user's supplemental characteristic.When the user needs the Adjustment System configuration, can be with the user's parameter correct in the random access memory device, system just can write the parameter that is modified in the unusual fluctuation data memory device and store this moment, then when system restart, after can earlier the user's supplemental characteristic in the edition data storage device being write the random access memory device, revise the content of random access memory device again according to the content of unusual fluctuation data memory device, wait to revise and finish, can guarantee that the user's supplemental characteristic in the random access memory device is a latest edition, so come initialization system according to the data in the random access memory device, can satisfy the up-to-date user demand of user side.Hereinafter will enumerate two embodiment and be illustrated, so that spirit of the present invention can be more obvious based on above-mentioned conception.
Please refer to Fig. 4, a kind of data memory device calcspar that its expression is provided according to inventive embodiment one.Data memory device 450 comprises non-volatile memory storage 45, random access memory device 37 and read-only memory storage 490, non-volatile memory storage 45 for example is EPROM (Erasable Programmable Read Only Memory) (Erasable Programmable Read Only Memory, EPROM), EEPROM (Electrically Erasable Programmable Read Only Memo) (Electrically Erasable Programmable Read Only Memory, EEPROM) or fast EPROM (Erasable Programmable Read Only Memory) (Flash Erasable Programmable Read OnlyMemory, Flash EPROM) etc., random access memory device 37 typically refers to random access memory (Random Access Memory, RAM), static RAM (Static RandomAccess Memory for example, SRAM) or dynamic RAM (Dynamic Random AccessMemory, DRAM) etc., 490 of read-only memory storages can be ROM (read-only memory) (Read OnlyMemory, ROM).Non-volatile memory storage 45 comprises unusual fluctuation data memory device 451 and edition data storage device 453 again, data memory device 451 and edition data storage device 453 are non-volatile elements, for example be EPROM, EEPROM or Flash EPROM etc., represented among annexation that it is relevant such as the figure, just repeat no more.In practice, non-volatile memory storage 45 can be a nonvolatile memory (for example: fast EPROM (Erasable Programmable Read Only Memory)), and unusual fluctuation data memory device 451 and edition data storage device 453 can be the zoness of different of this nonvolatile memory inside, do separating each other with different address.Same, data memory device 450 also is configured in the data management system, and in order to the required Various types of data of stocking system, data management system can be embedded system (embedded system) or open system.But it should be noted that, data memory device 450 is before dispatching from the factory, can be earlier the preset value of user's supplemental characteristic be recorded in the read-only memory storage 490, (for example, can utilizes this preset value to satisfy the Minimum requirements of initialization system configuration) in case of need when system during when machine.In addition, also store required each relative program (program) of initialization system in the read-only memory storage 490, when 290 fetch programs of data processing equipment are also carried out, can read supplemental characteristic simultaneously, with the initialization system configuration.For making the sentence straightforward, hereinafter will unify to use the initial version data to call the preset value of user's supplemental characteristic.When data memory device 450 is activated for the first time, data management system can be read from read-only memory storage 490 executive routines and with the initial version data earlier and it be write the random access memory device 37 again, just can finish the setting work of each related hardware in the system; Then, system can write the initial version data in the random access memory device 37 in the edition data storage device 453 and store, to finish the primary boot program of system.After system boot is finished, if the user demand of user side is different with preset value, the user just can revise each correlation parameter in the random access memory device 37 according to its actual demand, then, system can write the parameter that is modified in the random access memory device 37 in the unusual fluctuation data memory device 451 and store, to possess the amendment record of user's supplemental characteristic.For instance, user side changes the value of first parameter into m from M when first revision, value with second parameter when second revision changes n into from N, value with the 3rd parameter when third revision changes q into from Q, these supplemental characteristics just can be written into after modification in the unusual fluctuation data memory device 451 and store, so can record address, parameter value and each related data of first parameter, second parameter, the 3rd parameter in the unusual fluctuation data memory device 451.After system restart, can earlier the initial version data in the edition data storage device 453 be read and write in the random access memory device 37, and then upgrade random access memory device 37 according to the content of unusual fluctuation data memory device 451, first parameter, second parameter, the 3rd parameter that are about in the random access memory device 37 change to m, n, q respectively, so the user's supplemental characteristic in the random access memory device 37 can be remained on latest edition, to meet user's actual demand.
On the other hand, even if the modification of random access memory device 37 part system in the process that writes unusual fluctuation data memory device 451 interrupts suddenly, still can possess the preceding parameter modification record of system break so in the unusual fluctuation data memory device 451.The continuity previous example, user side changes the value of first parameter into m from M when first revision, value with second parameter when second revision changes n into from N, value with the 3rd parameter when third revision changes q into from Q, and these parameters that are modified all can be written in the unusual fluctuation data memory device 451 successively.Suppose that in the process with third revision, system interrupted suddenly when just parameter q write unusual fluctuation data memory device 451, only can possess the preceding parameter that is modified for twice so in the unusual fluctuation data memory device 451, just first parameter and second parameter.Then work as system restart, the initial version data are upgraded random access memory device 37 according to the content of unusual fluctuation data memory device 451 after being written into random access memory device 37 again, still can possess the user supplemental characteristic close in the back random access memory device 37 that finishes to be updated (in the random access memory device 37 except that the value Q of the 3rd parameter is not updated with actual demand, the value of first parameter is updated to m from M, the value of second parameter is updated to n from N), and can be as first parameter as the conventional practice, second parameter, the 3rd parameter is all replied respectively is preset value M, N, Q.
Because system only needed that modifications partly write unusual fluctuation data memory device 451 and gets final product when the parameters in the random access memory device 37 were modified, rather than as all the elements of random access memory device 37 being write back non-volatile memory storage 35 as the conventional practice, therefore modification part can store at short notice and finish, and has significantly reduced data and suffer the generation probability of interruption suddenly in the process that stores.Certainly, after data volume in unusual fluctuation data memory device 451 is accumulated to a certain degree, just can come each corresponding parameter in the revision data memory device 453 to upgrade the version of user's supplemental characteristic according to the content of unusual fluctuation data memory device 451, the continuity previous example, it is exactly content according to unusual fluctuation data memory device 451, change the value of first parameter in the edition data storage device 453 into m from M, the value of second parameter changes q from the value that N changes n and the 3rd parameter into into from Q, after treating that modification finishes, user's supplemental characteristic in the edition data storage device 453 is latest edition, so the time content of unusual fluctuation data memory device 451 can be removed (clear), after system restart, can read the user's supplemental characteristic and the initialization system configuration according to this of latest edition from edition data storage device 453, to satisfy user's actual demand.In addition, because system only needed the modification part is write in the unusual fluctuation data memory device 451 when the parameter in the random access memory device 37 was modified, even interrupt suddenly so will revise in the process that partly writes unusual fluctuation data memory device 451 system, can be not with the parameter that the is modified edition data storage device 453 that writes direct because of system yet, and the unlikely user's supplemental characteristic that influences in the edition data storage device 453, the parameter that promptly is modified has nothing to do with edition data storage device 453 fully in the process that writes unusual fluctuation data memory device 451, so former user's supplemental characteristic can't interrupt sustain damage suddenly because of system, after unusual condition takes place, once again during start-up system, can effectively avoid adopting the initial version data and come the situation of initialization system to produce.
The non-volatile memory storage that includes a unusual fluctuation data memory device and an edition data storage device has been described among the embodiment one, certainly in practical application, also can comprise a plurality of in the non-volatile memory storage, for example be 2 edition data storage devices, with usefulness as the user's supplemental characteristic that stores different editions.Please refer to Fig. 5, a kind of data memory device calcspar that its expression is provided according to embodiments of the invention two.Data memory device 550 comprises non-volatile memory storage 55, random access memory device 37 and read-only memory storage 490, and comprise unusual fluctuation data memory device 551, edition data storage device 553 and edition data storage device 555 in the non-volatile memory storage 55, represented among annexation that it is relevant such as the figure.Wherein, non-volatile memory storage 55 can be a nonvolatile memory (for example: fast EPROM (Erasable Programmable Read Only Memory)), and unusual fluctuation data memory device 551, edition data storage device 553 and edition data storage device 555 can be the zoness of different of this nonvolatile memory inside, do separating each other with different address.Unusual fluctuation data memory device 551 is the parameter that was modified in the random access memory device 37 in order to store, edition data storage device 553 is in order to store user's supplemental characteristic of different editions with edition data storage device 555, and read-only memory storage 490 is in order to store the program of initial version data and execution usefulness, wherein, unusual fluctuation data memory device 551, edition data storage device 553,555 functions that reach read-only memory storage 490 describe in detail in embodiment one, just do not add to give unnecessary details, then will be illustrated at the data processing method of this structure.The practice of embodiment two, be to utilize two edition data storage devices 553,555 to store user's supplemental characteristic of different editions respectively, when system start-up, the totalling that data processing equipment can read earlier in the two edition data storage devices 553,555 is checked a yard CS, if it is all correct that both totallings are checked yard CS, then read the newer supplemental characteristic of version; If have only wherein one correct, the user's supplemental characteristic that then reads this person and write down; If it is all incorrect that the totalling of two edition data storage devices 553,555 is checked yard CS, then in read-only memory storage 490, read the initial version data, to finish the setting work of system.Moreover, when the supplemental characteristic in the edition data storage device 553,555 need upgrade, data processing equipment can in two edition data storage devices 553,555, select out earlier version older one, upgraded at this person's content again, make it have more recent version, hereinafter will describe in detail at the running program of this practice.
When data memory device 550 is activated for the first time, since the totalling of edition data storage device 553,554 check sign indicating number be invalid, so system can read the initial version data in read-only memory storage 490 earlier, and writes in the random access memory device 37, to finish the setting work of system.On the other hand, edition data storage device 553 and edition data storage device 555 are equipped with the sign F of the usefulness of LSN, after the initial version data write random access memory device 37, random access memory device 37 can write back the initial version data in edition data storage device 553 and the edition data storage device 555, can all be made as 0 this moment with the sign F of the two, all identical with the content of representing two edition data storage devices with the initial version data, can be referred to as user's supplemental characteristic of the 0th edition.After starting for the first time, enter into immediately and open the beginning program implementation, so-called start-up routine, briefly, the user's supplemental characteristic refresh routine that is carried out when the user's supplemental characteristic in two edition data storage devices is the 0th edition exactly hereinafter will be illustrated at this program.
Because the user's supplemental characteristic under opening the beginning program in edition data storage device 553 and the edition data storage device 555 all is all the 0th edition, therefore system is when restarting, and can choose wherein one wantonly and write in the random access memory device 37 after its user's supplemental characteristic read; Behind the content modification of random access memory device 37, system can write storage in the unusual fluctuation data memory device 551 with revising part.When system restarts once again, can choose an edition data storage device equally wantonly and its user's supplemental characteristic read after write in the random access memory device 37, and then according to the content update random access memory device 37 of unusual fluctuation data memory device 551, so the user's supplemental characteristic in the random access memory device 37 can be remained on latest edition, to meet user's actual demand.It should be noted that, after data volume in unusual fluctuation data memory device 551 is accumulated to a certain degree, system just can choose one wantonly to carry out the version updating action of user's supplemental characteristic from edition data storage device 553 and edition data storage device 555, and the totalling that upgrades this edition data storage device after version updating finishes is in the lump checked yard CS and sign F, and unusual fluctuation data memory device 551 emptied, its concrete practice will be in hereinafter being illustrated.
When carrying out version updating, because the content of two edition data storage devices is identical, therefore system can choose one wantonly with the object as renewal from edition data storage device 553 and edition data storage device 555, supposing the system selects edition data storage device 553 as the object that upgrades, so just the user's supplemental characteristic in the random access memory device 37 all can be write back in the edition data storage device 553 and the 0th edition data are override, to finish the refresh routine of version, after version updating finished, edition data storage device 553 can produce new totalling according to its content and check a yard CS.Because the content of random access memory device 37 is the most recent parameters that system adopted at that time, so possess too after the data in the edition data storage device 553 are updated up-to-date user's supplemental characteristic arranged, can be made as 1 this moment with the sign F of edition data storage device 553, to store user's supplemental characteristic of the 1st edition in the expression edition data storage device 553; Moreover, owing in version updating finishes back edition data storage device 553, promptly store up-to-date user's supplemental characteristic, just the content of unusual fluctuation data memory device 551 can be removed fully so carve; After unusual fluctuation data memory device 551 is cleared,, just the modification part can be write unusual fluctuation data memory device 551 and be stored if the content of random access memory device 37 is revised again to some extent.Because its storing mode of supplemental characteristic of being modified is in proper order, thus can wait until the unusual fluctuation data memory device expired after again with all Data Update to the edition data storage device, therefore may reduce the indegree of writing of Flash, the life-span of prolongation Flash.
When treating system restart, if it is all correct that the totalling of two edition data storage devices is checked sign indicating number, the sign that just can compare two edition data storage devices earlier with select have more recent version the edition data storage device with in the user's supplemental characteristic feed-in random access memory device 37 with new edition, since this moment edition data storage device 553 be masked as 1 and edition data storage device 555 be masked as 0, so the data in the edition data storage device 553 are new (in the present embodiment as can be known, its versions of data of sign the greater is newer), therefore system can read the content of edition data storage device 553 and write in the random access memory device 37, upgrades random access memory device 37 according to the content of unusual fluctuation data memory device 551 again.After the data volume in the unusual fluctuation data memory device 551 is accumulated to a certain degree again, system just can select out one once again to carry out the version updating action of user's supplemental characteristic from edition data storage device 553 and edition data storage device 555, this person can produce new totalling and check yard CS and sign F after version updating finishes, this moment, system just can empty unusual fluctuation data memory device 551, to continue the variation of record user supplemental characteristic.It should be noted that, because the content in the two edition data storage devices is inequality at this moment, when therefore carrying out version updating, system can find according to the sign of the two version older one and upgraded, therefore the time edition data storage device 553 be masked as 1 and edition data storage device 555 be masked as 0, so the data in the edition data storage device 555 are older as can be known, just the user's supplemental characteristic in the random access memory device 37 is all write back in the edition data storage device 555 and the 0th edition data are override, to finish the refresh routine of version, after pending data upgrades and finishes, the sign F of edition data storage device 555 can be made as 2, to store user's supplemental characteristic of the 2nd edition in the expression edition data storage device 555.
Briefly, the version updating of user's supplemental characteristic is to utilize random access memory device 37 content at that time to override legacy version in the edition data storage device, which, just decide by the sign in each edition data storage device as for selecting edition data storage device as upgating object.In embodiment two, user's supplemental characteristic version in this edition data storage device of the more little expression of setting value of sign is old more, therefore system can find the object of sign minimum (just content the oldest) as version updating in each edition data storage device, and after renewal finishes sign is reset to maximum.On the other hand, when system restart, system can find sign maximum and its content is write in the random access memory device in each edition data storage device, because the user's supplemental characteristic version in this edition data storage device of the big more expression of setting value of sign is new more, so this selection mode can find the user's supplemental characteristic near user's request.After the system that treats is written into the random access memory device with user's supplemental characteristic of latest edition, again according to the content of the parameter modification random access memory device in the unusual fluctuation data memory device, after treating that modification finishes, just can make the interior parameters of random access memory device meet user's actual demand.
With this structure, if aborted takes place in system when carrying out the version updating of user's supplemental characteristic, it is inevitable wrong that the edition data storage device that is so upgrading its totalling when system restart is checked yard CS, but because system can confirm earlier when restarting whether the totalling of two edition data storage devices is checked sign indicating number correct, so still can select the correct and newer user's supplemental characteristic of version of content in this case, not influenced by the aborted of system at all.Be the operating process that makes embodiment two straightforward more, hereinafter will cooperate the program of flowchart text system start-up and version updating.
