Specific embodiment
For make present invention solves the technical problem that, the technical scheme that uses and the technique effect that reaches it is clearer, below
The technical scheme of the embodiment of the present invention will be described in further detail with reference to accompanying drawing, it is clear that described embodiment is only
It is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, those skilled in the art exist
The every other embodiment obtained under the premise of creative work is not made, the scope of protection of the invention is belonged to.
Embodiment one
Fig. 1 is a kind of flow chart of the compression method of executable file that the embodiment of the present invention one is provided.The present embodiment
Method can be performed by the compression set of such as executable file such as TV and/or TV set-top box, wherein, the method can be by portion
Affix one's name to software and/or hardware in such as TV and/or TV set-top box to implement, the software and/or hardware can typically be integrated in
In certain embedded system.As shown in figure 1, the method may include steps of：
S110：Analyze the functional attributes and storage format attribute of executable file each several part data.
Wherein, executable file refers to the file that load and execution is carried out by operating system, and that is mentioned in the present embodiment holds
Style of writing part is preferably executable binary system (bin) file.Above-mentioned executable binary file can be to pass through compression
The binary file for the treatment of, or the binary file without overcompression treatment.Wherein, those skilled in the art can be according to can
The compressing mark carried in the binary file of execution judges whether the binary file is compressed.
Exemplary, the storage format attribute of executable file each several part data can be from each several part data correspondence storage road
Obtained in the identifier of the mark partial data correspondence storage format added in footpath, generally include following three kinds of situations：
1st, any compressing mark has been not added with it in correspondence store path；
For the executable file that any compressing mark is not added with each several part data correspondence store path, compiler exists
Normal process of compilation need to be only completed during compiling this document, without doing any compression and decompression.
2nd, it is added with the relatively low compressing mark of compression ratio in correspondence store path；
Preferably, the default storage format attribute in the embodiment of the present invention refers to and is preset according to first in store path
What the executable file that storage format (such as identifier "-g ") or the second default storage format (such as identifier " -7 ") are preserved had
Characteristic attribute.The corresponding compression ratio of above two storage format is different, and the first corresponding compression ratio of default storage format is relatively low, the
The two corresponding compression ratios of default storage format are higher.Specifically, when the marker character of the first default storage format is "-g ".If
When detecting the presence of "-g " identifier in the corresponding store path of certain partial data of executable binary file, then explanation is compiled
Device is translated during the partial data for compiling the executable binary file, the side of smaller compression ratio is pressed to the partial data
Formula carries out overcompression treatment, and the binary file is stored to save the memory space shared by the binary file, and then save
The material cost of hardware (such as storage chip).
3rd, it is added with compression ratio compressing mark higher in correspondence store path.
Preferably, when the identifier of the second default storage format is " -7 ".If certain part of executable binary file
If detect the presence of " -7 " identifier in the corresponding store path of data, illustrate that compiler is compiling the binary file
During the partial data, overcompression treatment is carried out in the way of larger compression ratio to the partial data, be compared to identifier
The default storage format of the first of "-g ", above-mentioned compress mode can further save depositing shared by the executable binary file
Storage space, the material cost of the binary file hardware is stored to save.
It should be noted that because compression algorithm and technology are numerous, executable binary file each several part data are deposited
Storage form is not limited to three kinds of forms enumerated above.
S120：According to functional attributes, compressible target data in each several part data is identified.
Further, it is necessary to according to the work(of each several part data before executable binary file each several part is by compression
Can attribute this fundamental characteristics, judge whether each several part data in the executable binary file can be compressed.Show
Example property, the functional attributes of each several part data in executable binary file may include but be not limited to such as storage attribute, pressure
Contracting or decompression attribute etc..In specific operation process, for executable with decompression attribute or with flag attribute
Binary file data, then cannot run counter to its data attribute it is done compression treatment；And for storage attribute
Data in binary file, then can be compressed to save memory space to it.
Exemplary, illustrated by taking the practical structures of system as an example below, the preferred NOS of the system (No Operating
System, does not have operating system) system：
00113：#define IMG_INFO_OFFSET 0x21000
00112：#difine MAGIC_BOOTLOADER 0x55AA1234
00113：#define MAGIC_APP 0x55AA5678
00114：#define MAGIC_IMAGE_END 0x55AAABCD
Fig. 2 a are to write a kind of executable two generated after flash memory (Flash Memory, general abbreviation FLASH) operation to enter
File data processed.As shown in Figure 2 a, operated by entering row write FLASH to the structure, in actual generation file,
0x21000 is the data being actually written into.It is flag code part because the address is corresponding, then the file data for generating cannot be by
Compression, it is necessary to stored with the actual byte-sized for taking.
Exemplary, for following executable binary file datas：
00303：#difine BIN_PACKAGE_HEADER_ID0 0x54454C09
00304：#difine BIN_PACKAGE_HEADER_ID1 0x58336900
00289：PlaceU32_ (BIN_PACKAGE_HEADER_ID0),
PlaceU32_(BIN_PACKAGE_HEADER_ID1)
Specifically, Fig. 2 b are to write another the executable binary file data generated after FLASH operations.Such as Fig. 2 b institutes
Show, it will be appreciated by persons skilled in the art that in the binary file, the corresponding data of address 0002100h and write-in
Data (54454C09 and 58336900) are consistent, then show that the partial data in the binary file can be what is compressed.
It is analyzed by the functional attributes of the binary file each several part data to can perform, this can be quickly recognized
The target data that can be compressed in binary file, so that quick lock in is compressible, i.e., pending object reduces process range.
S130：Storage format attribute according to target data, obtains the Compression Strategies of target data.
Exemplary, the corresponding Compression Strategies of different storage format attributes are different.For example：
If being not added with the storage attribute of any compressing mark in target data correspondence store path, the number of targets is illustrated
According to not compressing completely.Accordingly, such that it is able to draw the next step Compression Strategies of the target data, you can with according to certain pressure
Contracting mode is compressed to the partial data, so as to reduce the memory space of the target data；
If target data is stored in respective path according to the form of the first default storage format (such as identifier is "-g "),
Then explanation target data is compressed by the relatively low compress mode of compression ratio.Accordingly, it can be deduced that the target data is next
The Compression Strategies of step, you can compress the partial target data by certain compress mode higher than current compression rate；
If target data is stored in respective path according to the form of the second default storage format (such as identifier is " -7 "),
Then explanation target data can currently be compressed by certain compression ratio compress mode higher.Accordingly, it may be possible to draw the mesh
The Compression Strategies of data next step are marked, that is, is possible to that the partial target number cannot be lifted by changing compress mode, further again
According to compression ratio.
S140：According to Compression Strategies, target data is compressed, and updates the storage format attribute of target data, obtained
Executable file after to compression.
For compressible target data, according to fixed Compression Strategies in above-mentioned steps, place can be compressed to it
Reason, while the storage format attribute in the corresponding store path of updatable object data so that target data after compression is deposited
The storage attribute of a configuration is corresponding with current Compression Strategies.Consequently facilitating being selected and current compression strategy when the target data is performed
Corresponding decompression strategy.Therefore, by recognizing the storage format attribute of target data, it may be determined that go out the target data whether by
Compression, or processed through overcompression according to what kind of mode.
Further, after the executable file after compression is stored in FLASH, for the remaining memory spaces of FLASH,
Data can be preserved by making full use of its remaining space so that the utilization rate of the FLASH memory headrooms reaches maximum.Specifically,
Its optimization method is as follows：
Fig. 3 a are the data store organisation distribution map of TV FLASH internal memories before the optimization that the embodiment of the present invention one is provided.Such as
Shown in Fig. 3 a, in the memory space of 0-57BANK (storage cell), the executable file of main storage software, so executable text
The size of part is 58 × 64K=3712K to the maximum.If the size of executable file is more than this space, will there is covering number
According to the risk in area.And for the size then according to practical structures body of the data beyond executable file and the channel number of reality
Carry out the distribution of memory space.After total data storage is completed, the only remaining free space of 2K, i.e. memory space surplus
It is not enough.Therefore, in order to optimize to reach the requirement simplified to memory space, need to be saved again in 7 BANK in fig. 3 a
Go out a BANK and carry out data storage.Specific optimization process is as follows：
By analysis, in the 63rd BANK, real data only have 304 BYTE, but the memory space of FLASH is
Divided with BANK as unit, so, the data of 304 BYTE occupy whole 63rd in the 63rd BANK
BANK, causes the waste of FLASH memory space resources.Fig. 3 b are TV FLASH after the optimization that the embodiment of the present invention one is provided
The data store organisation distribution map of internal memory.As shown in Figure 3 b, by the HDCP that upgrades, can be by HDCP (High-
Bandwidth Digital Content Protection, HDCP) data of part directly write to the internal memory of regulation (such as
58 BANK) in.In this manner it is possible to save a BANK to deposit other program codes more.In addition, can also be by data
Storage mode be revised as the mode not preserved, whole form will be initialized in system initialization, then switch it is different
During sequential, data can be directly loaded from form, so can save a BANK out again.Therefore, by using above-mentioned optimization
The mode of Memory Allocation, can reach the technique effect for further saving memory space.
Optionally, the method for saving memory space, it will be appreciated by persons skilled in the art that in rear onward encoding
The picture that sequence need not be used in performing, can delete, or be compiled to picture by it in routine data
The compression ratio of Shi Xiugai pictures reduces the size of the executable file of generation picture, and then further required for saving program
Memory space.
Optionally, also directly deletion can be revised as by the pattern that is shielded the code that need not be performed in program
This part is shielded the pattern that makes it be not carried out code, reaches the technology effect for further saving executable file memory space
Really.Because the technological means of the shielding code taken does not perform this partial code simply, but in former executable binary system
In file, the code being not carried out that this part is shielded still is physically present in former executable binary file, institute
Certain amount of physical memory still can be occupied with the code that this part is shielded.If for being shielded deliberately to be not carried out
Code, take the form for directly deleting code, then because code is deleted by physical, be not carried out compared to shielding
Technological means, deleting code then can further save the memory space of executable binary file.
A kind of compression method of executable file is present embodiments provided, in the work(of analysis executable file each several part data
After energy attribute and storage format attribute, the functional attributes such as storage, compression or decompression according to executable file each several part data,
May recognize that the target data that can be compressed in the executable file each several part data.Storage format category according to target data
Property, can obtain the Compression Strategies of target data.Wherein, Compression Strategies may include not to be compressed, be compressed, and be pressed according to than original
The larger new compress mode of shrinkage is compressed, and is compressed according to new compress mode more less than former compression ratio
Situation.According to Compression Strategies, target data is compressed, and updates the storage format attribute of target data, after being compressed
Executable file.By using above-mentioned technical proposal, can cause that the executable file after compression takes less storage empty
Between, the technique effect of the storage hardware material cost required for saving executable file is reached, so as to lift corresponding producing indirectly
The market competitiveness of product.
