It jumps to the memory address and executes the patch for having called in the address.
Logical construction in relation to patch release file is shown in 2 for patch release file schematic diagram provided in an embodiment of the present invention institute
Show.Patch release file is made of the total several patch release records of patch release record.Every patch release record is by patch rope
Quotation marks, version number, edition data composition.Patch call number is corresponding with the patch call number in patch record file and keeps
Consistent, single-chip microcontroller obtains the value of patch call number from patch record file and search index number is joined in patch release file
Consistent patch release records number therewith, to further obtain information related with patch.Version number is to identify in version
The sum for the patch version field for including in total in notebook data.Edition data is made of the several patch release fields of version.Patch version
This field is made of patch release, patch address and patch switch.Single-chip microcontroller gets patch data according to patch call number, and
The patch release field in patch data is polled according to version number；Polling purpose is to look for patch switch and is arranged to
The patch field uniquely activated opened.Single-chip microcontroller gets according to the patch field of the activation found and is currently active use
Patch patch address, finally according to the address single-chip microcontroller obtain patch and complete memory copying execution patch

Fourth version file carries out query processing, generates the first patch release record, specifically includes:
Step 61, the single-chip microcontroller obtains the record sum of the patch release file, generates the second record sum；
Step 62, it is 0 that the value of the second record queries result, which is arranged, in the single-chip microcontroller, and the value of the second recording indexes of setting is 1；
Step 63, the single-chip microcontroller obtains the second recording indexes patch release and records word according to the patch release file
Section generates first temporary patch's colophon；
Step 64, the single-chip microcontroller disassembles first temporary patch colophon, obtains first temporary patch
First temporary patch's call number byte of colophon generates first temporary patch's call number；
Step 65, the single-chip microcontroller judge first temporary patch call number value whether with the first patch call number
Be worth it is equal, if the value of first temporary patch call number is equal with the value of the first patch call number, setting described in
The value of second record queries result is 1, goes to step 68；If the value of first temporary patch call number and described first is mended
The value of fourth call number is unequal, then goes to step 66；
Step 66, the value that second recording indexes are arranged in the single-chip microcontroller adds 1；
Step 67, the monolithic judges whether the value of second recording indexes is greater than the second record sum, if described
The value of second recording indexes is greater than the second record sum, goes to step 68；If the value of second recording indexes is little
In the second record sum, then step 63 is gone to；
Step 68, the single-chip microcontroller judges whether the value of the second record queries result is 1, if second record queries
As a result value is 1, then extracts whole bytes of first temporary patch colophon, generates the first patch release note
Record；If the value of the second record queries result is 0, first patch release is set and is recorded as sky.

The single-chip microcontroller disassembles first patch release record, obtains the first edition of the first patch release record
This number section, generates the first version number；And the first version data byte of the first patch release record is obtained, it generates
The first version data.
8. method according to claim 1, which is characterized in that the single-chip microcontroller is according to the first version number, to described
One edition data is disassembled, and is generated the first patch address, is specifically included:
Step 81, the single-chip microcontroller generates the first field sum according to the first version number；
Step 82, it is 0 that the value of the first Field Inquiry result, which is arranged, in the single-chip microcontroller, and the value of the first field index of setting is 1；
Step 83, the single-chip microcontroller obtains the first field index patch release field word according to the first version data
Section generates first temporary patch's version field；
Step 84, the single-chip microcontroller disassembles first temporary patch version field, obtains the first temporary patch switch
Byte generates the first temporary patch switch；
Step 85, the single-chip microcontroller judges whether the value of the first temporary patch switch is out, if the described first interim benefit
The value of fourth switch is to open, then the value that the first Field Inquiry result is arranged is 1, goes to step 88；If described first is interim
The value of patch switch is to close, then goes to step 86；
Step 86, the value that first field index is arranged in the single-chip microcontroller adds 1；
Step 87, the monolithic judges whether the value of first field index is greater than the first field sum, if described
The value of first field index is greater than the first field sum, goes to step 88；If the value of first field index is little
In the first field sum, then step 83 is gone to；
Step 88, the single-chip microcontroller judges whether the value of the first Field Inquiry result is 1, if first Field Inquiry
As a result value is 1, then extracts the first patch address byte of first temporary patch version field, generates first patch
Address；If the value of the first Field Inquiry result is 0, first patch address is set for sky.
9. method according to claim 1, which is characterized in that the single-chip microcontroller carries out effectively first patch address
Location checking treatment, specifically includes:
When first patch address being not sky and within the scope of the patch address as defined in the single-chip microcontroller, it is described effectively
Location verifies successfully.
