Realize best mode of the present invention
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:
Software version compatibility of the present invention is as follows in the method for different hardware:
The core that method realizes is that a software version is supported multiple hardwares, is actually a plurality of files are merged in the file, and writes son file information in the file beginning, identifies the querying method of the software son file of supporting various different hardware.The form of whole software version file is as follows
| File header | Son file information 1 | ……. | Son file information N | Son file piece 1 | …… | Son file piece N |
Fig. 6 is the flow chart of steps of the inventive method, comprises the steps:
File header
| File identification | File size | Son file information number | The file header verification |
In a file header, comprised file identification, file size, son file information number, several parts of file header verification.Wherein:
File identification is a specific magic number (Magic numbers, magic number refers to the string number of binary file beginning place), and the classification of refering in particular to file is used for judging fast file layout.
File size equals the length of whole software version file.
Son file information number illustrates the number of the son file that contains in the current file.
The file header verification be used for the whole file header of verification and from son file information 1 to son file information N scope in data whether correct.
From file header, can index the number of son file, and whether the verification file head is correct.
Son file information
| Release type | Version number | Son file piece start address | The son file block length | The son file block check |
After confirming that file header is correct, just can all son file information be scanned, has comprised following information in the son file information:
Release type
Version number
The son file start address
The son file block length
The son file block check
Release type is a main discriminant information, and whether the type of hardware that on behalf of this son file, it support conforms to type of hardware by differentiating release type, just can obtain the son file piece that current hardware needs.
Whether version number is mainly used in version management, can differentiate this this software and overlap together with other softwares.
The son file start address has provided the offset address of son file piece in whole file.
The son file block length is meant the length of the son file piece that sub-fileinfo is represented.
The son file block check is meant the verification of the son file piece that sub-fileinfo is represented.
Like this,, just can find out the son file information corresponding,, just can find blocks of files by this son file information with current hardware by scanning to the sub-information of file.
Step 603 goes out the son file piece according to the son file information index.
After having obtained current son file information, can extract the son file piece, read whole son file piece, and carry out the son file block check in the start offset address in software version.
Step 604 uses this son file piece to be this edition operating software.
After obtaining this son file piece, this son file piece can be generated in addition an independent version file, perhaps just when using this son file piece, from file, extract again by needs.
Fig. 1 is that flow process is extracted in the verification of version file head, comprising:
Step 101: differentiate file identification, the then execution in step 102 that meets the requirements, otherwise execution in step 106;
Step 102: read son file information number;
Step 103: calculation document message length;
Step 104: a calculation document verification;
Whether step 105: it is correct to differentiate verification, is execution in step 107 then, otherwise execution in step 106;
Step 106: carry out abnormality processing;
Step 107: enter next flow process.
After version file head essential process verification specified data is error-free, can be effective, the verification in the file header is the verification of whole file header and all son file information.File header by verification after, extract son file information number, as index son file range of information.
Fig. 2 is a son file information index flow process; Comprise:
Step 201: current son file information index zero setting;
Step 202: judge the FileVersion type whether with the hardware coupling, be execution in step 206 then, otherwise execution in step 203;
Step 203: current son file information index adds one;
Step 204: judge that whether current son file information index is maximum, be execution in step 205 then, otherwise return step 202;
Step 205: carry out abnormality processing;
Step 206: extract current son file information and preservation;
Step 207: enter next flow process.
Fig. 2 flow process is the continuation of Fig. 1 flow process, needs to use the son file information number that reads in Fig. 1 flow process in the son file information index flow process, as the maximal value of son file information index.Flow process travels through all son file information, till finding required son file information.
Fig. 3 is that the son file piece extracts flow process, comprising:
Step 301: obtain son file information;
Step 302: read son file piece start address;
Step 303: read the son file block length;
Step 304: calculate son file piece and verification;
Step 305: whether that deposits in the verification of judge calculating and the son file information equates, is execution in step 307 then, otherwise execution in step 306;
Step 306: abnormality processing;
Step 307: read whole son file piece;
Step 308: finish.
Fig. 3 flow process is right after Fig. 2 flow process, the suction parameter that the current son file information of obtaining in Fig. 2 flow process is Fig. 3 flow process.Flow process obtains the skew and the length of son file piece and the verification of calculation document piece by current son file information.The son file piece that extracts has been exactly available target data.
This instructions provides two kinds of embodiments commonly used.
Embodiment one, higher level's opertaing device are to the selectivity software loading of subordinate equipment:
As shown in Figure 4, being higher level's opertaing device carries out the flow process of software loading to subordinate equipment, comprising:
Step 401: the type of hardware that obtains subordinate equipment;
Step 402: obtain the son file piece that is fit to subordinate equipment;
Step 403: this son file piece is issued as an independent software version.
When higher level's opertaing device carries out software loading to subordinate equipment, higher level's opertaing device can not be loaded into subordinate equipment with whole software versions, and after the son file piece that only needs to adapt to the subordinate equipment needs reconstitutes a new software version, directly be loaded into subordinate equipment, the benefit of doing like this is to save the storage resources of subordinate equipment.
Embodiment two, the hardware device selectivity is used the son file piece:
Shown in Figure 5 is the flow process that the hardware device selectivity is used the son file piece, comprising:
Step 501: from version file, extract the son file piece;
Step 502: use this son file piece.
Hardware device all downloads to the whole software version in the memory storage of equipment, then according to current type of hardware, determines the son file piece of extraction, and uses this son file piece.
The difference of these two kinds of embodiments is actually on different equipment and extracts the son file piece, and implementing in first is to extract the son file piece at higher level's opertaing device, and to implement in second be to extract the son file piece at this equipment.
