Detailed Description
When the device based on the embedded operating system is started, the starting function is executed by reading the image file in the flash into the memory, and the starting of the core function can be realized only after the image file is completely read into the memory, so that the starting speed of the core function of the device is influenced. At present, the problem is solved in the following two ways.
One is to cut and optimize source codes to make the mirror image file smaller, thereby prolonging the time required by reading and accelerating the starting speed. However, the redundant code is few under the condition that the application framework is designed reasonably, and the effect of reducing the image file by removing the redundant code is very limited. If the image file is reduced by modifying the adjustment code, not only is technically complicated and time-consuming and labor-consuming, but also code logic may be damaged, and the obtained effect is very little.
The other mode is that a small enough image file only containing the core function is manufactured, and after the core function is started based on the image file, the complete image file is read from the flash to the memory to execute other related function starting. In this way, since the newly manufactured image file and the complete image file belong to different images, independent system resources are occupied after the images are respectively started, synchronous sharing needs to be realized, the operation is very complicated, errors are easy to occur, resources are wasted, and the core function even needs to be restarted in many cases.
Based on the above research, the present application provides a method for compiling an image file, which includes obtaining a first file set that a core function image in a target file set depends on and a second file set that a non-core function image depends on, and sequentially ordering the first file set and the second file set. And modifying the link script of the complete mirror image according to the rearranged target file set so as to lay out the first file set to the front end of the complete mirror image to obtain a core function mirror image, and lay out the second file set to the rear end of the complete mirror image to obtain a non-core function mirror image. Therefore, the core function mirror image and the non-core function mirror image are separated, so that the core function mirror image can be read firstly when being read subsequently, the starting of the core function of the equipment is completed, and the requirement for quickly starting the core function is met.

The communication module 130 is used for establishing a communication connection between the electronic device 10 and another communication terminal through a network, and for transceiving data through the network.
It should be understood that the configuration shown in fig. 1 is merely a schematic diagram of the configuration of the electronic device 10, and that the electronic device 10 may include more or fewer components than shown in fig. 1, or have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
Referring to fig. 2, fig. 2 is a flowchart illustrating an image file compiling method according to an embodiment of the present application, where the image file compiling method can be executed by the electronic device 10 shown in fig. 1. It should be understood that, in other embodiments, the order of some steps in the image file compiling method of the embodiment may be interchanged according to actual needs, or some steps may be omitted or deleted. The detailed steps of the image file compiling method are described as follows.
Step S210, a target file set required by generating a complete mirror image is obtained, wherein the complete mirror image comprises a core function mirror image and a non-core function mirror image.
Step S220, rearranging the target files in the target file set to obtain an rearranged target file set, where the rearranged target file set includes a first file set and a second file set that are sequentially arranged, the first file set includes the target files corresponding to the core function mirror image, and the second file set includes the target files corresponding to the non-core function mirror image.
Step S230, modifying the link script of the complete mirror image according to the rearranged target file set, laying out the first file set to the front end of the complete mirror image to obtain a core function mirror image, and laying out the second file set to the rear end of the complete mirror image to obtain a non-core function mirror image.
The image file exec (executable file) is an executable file, and is one of the types of elf (executable and linkable format). Among them, ELF is an executable and linkable format, developed and released by UNIX Systems Laboratories (USL) as Application Binary Interface (ABI), and is also the main executable file format of LINUX.
The generation of the mirror image file depends on a target file rel (relocatable file), which is a kind of redirectable file, i.e. only the compilation is completed and the file without link is also one of the ELF types. When the device based on the embedded operating system is started, the image file in the flash area needs to be read and loaded into the memory for execution, so that the starting process is completed.
In this embodiment, the image file is modified so that the image file related to the core function can be read and executed first subsequently. The modification of the mirror image file can be realized only by modifying the target file. In this embodiment, a target file set required for generating a complete mirror image is obtained, for example, denoted as a set a, where the target file set is composed of target files related to the complete mirror image extracted from a static library file and original target files in a compilation environment. And the full image includes a core function image associated with a core function of the device and a non-core function image associated with a non-core function other than the core function.
If the core function mirror image and the non-core function mirror image contained in the complete mirror image are to be separated, and the core function mirror image is to be read in a subsequent priority manner, the target files in the target file set need to be classified and sorted.
In this embodiment, the target file set includes a plurality of target files, where the plurality of target files includes a target file on which the core function image depends and a target file on which the non-core function image depends. The target files included in the target file set may be rearranged, and the rearranged target file set may be divided into a first file set (denoted as set B) and a second file set (denoted as set C). The first set of files and the second set of files are subsets of the target set of files. And the target files contained in the first file set are all target files corresponding to the core function mirror image. The target files contained in the second file set are all target files related to the non-core function mirror image.
In the rearranged target file set, the first file set is arranged at the front end of the second file set. And then the complete mirror image is rearranged according to the link script of the rearranged target file set, so that the link disorder caused by the change of the link mode can be avoided when a new local complete mirror image is compiled. On the basis, the first file set can be arranged at the front end of the complete mirror image to serve as a core function mirror image, and the second file set can be arranged at the rear end of the complete mirror image to form a non-core function mirror image. The link script is also called a program loading file, and determines how to allocate storage base addresses of related data when generating the image file.
In this embodiment, the link script of the complete mirror image is modified by classifying and reordering the target files in the target file set in the above manner, so as to obtain the complete mirror image with the front end serving as the core function mirror image and the rear end serving as the non-core function mirror image. Therefore, when the complete mirror image is read subsequently, the core function mirror image can be preferentially read so as to quickly finish the starting of the core function.
Typically, the ratio of the core function image of the front end in the full image is small, for example, it may be only one tenth of the full image. Therefore, based on the mode of arranging the core function mirror image at the front end, the time delay caused by reading the flash can be greatly reduced, and the starting of the core function is accelerated. In addition, because the core function mirror image at the front end and the non-core function mirror image at the rear end belong to a complete mirror image, the resources of the two can be shared without additional synchronous work. From the view point of complete operation of the program, the mode of starting the core function mirror image of the front end firstly and then starting the non-core function mirror image of the rear end is adopted subsequently, and almost no difference exists between the mode of directly starting the complete mirror image and the mode of starting the non-core function mirror image of the rear end.
Referring to fig. 3, in the embodiment, the foregoing may be specifically implemented in the following manner when the target file set is rearranged:
step S221, obtaining all first class files corresponding to the core function mirror image in the target file set and all second class files corresponding to the non-core function mirror image in the target file set.
Step S222, rearranging the first class files and the second class files in the target file set so that any one of the first class files is arranged at the front ends of all the second class files to obtain an rearranged target file set, where the rearranged target file set includes a first file set composed of the first class files and a second file set composed of the second class files, which are arranged in sequence.
In this embodiment, all the target files included in the target file set are classified first, so as to obtain a first type of file related to the core function image and a second type of file related to the non-core function image. And rearranging all the first-class files and the second-class files so as to arrange all the first-class files at the front end and all the second-class files at the rear end. And the two types of files are divided into a first file set and a second file set respectively.
Alternatively, in practice, it may not be clear which target files in the set of target files are the target files on which the core function image depends. Therefore, referring to fig. 4, the first type of file related to the core function image in the target file set can be determined by the following method, and then the second type of file related to the non-core function image can be determined by the following method:
and step S2211, shielding codes irrelevant to the core function in the system, and compiling the unshielded codes to generate a target image.
Step S2212, obtaining the target file required when the target image is generated in the target file set, as the first type of file corresponding to the core function image.
Step S2213, regarding other target files except the first type of file in the target file set as second type of files corresponding to the non-core function image.
In implementation, the code irrelevant to the core function can be shielded, and a target image only containing the core function and the core part of the operating system is generated by compiling, wherein the target image is the core function image. And analyzing all target files depended by the target image through a compiler tool, namely the target files are first-class files corresponding to the core function image. And the other target files except the first type of files in the target file set are second type files corresponding to the non-core function mirror image.
In this embodiment, after the core function image and the non-core function image are obtained, in order to facilitate subsequent separation of the core function image and the non-core function image, the link script of the complete image may be modified to perform the alignment operation. The relative positions of the core function mirror image and the non-core function mirror image in the complete mirror image can be adjusted by the link script, the core function mirror image is arranged at the front end of the complete mirror image, the non-core function mirror image is arranged at the rear end of the complete mirror image, and the offset position of the non-core function mirror image can be understood as a connection point between the core function mirror image and the non-core function mirror image. Alternatively, the link script of the full image may be modified so that the offset position of the non-core function image in the full image is aligned by a preset size. In this embodiment, the unit of M is too large, so the preset size is 1K.
In this embodiment, in order to perform reading with the core function image and the non-core function image as a single whole when reading the image file subsequently, please refer to fig. 5, and on the basis, the following steps are further included:
step S310, separating the core function image and the non-core function image in the complete image.
Step S320, compressing the separated core function mirror image to obtain a core compressed file, and adding the attribute information of the core function mirror image to the front end of the core compressed file.
And step S330, compressing the separated non-core function mirror image to obtain a non-core compressed file, and adding the attribute information of the non-core function mirror image at the front end of the non-core compressed file.
In this embodiment, when the core function image and the non-core function image are separated, the connection point of the core function image and the non-core function image is used as a separation point to separate. The core function mirror image and the non-core function mirror image can be compressed to save the storage space of Flash. When the core function image and the non-core function image are compressed, the same compression format may be used, or different compression formats may be used, and the embodiment is not limited specifically.
After the core function mirror image is compressed, adding header information containing the attribute information of the core function mirror image at the front end of the core compressed file. The attribute information of the core function image includes the size of the core function image, the offset address of the core function image, and the like. Similarly, after the non-core function image is compressed, header information containing the attribute information of the non-core function image is added to the front end of the non-core compressed file. The attribute information of the non-core function image includes the size of the non-core function image, the offset address of the non-core function image, and the like.
After the header information is compressed and added, the core compressed file and the non-core compressed file can be stored in different flash areas, or the core compressed file and the non-core compressed file can be combined to form a complete image file, and the complete image file is completely stored in one flash area.
On the basis, when the device receives the starting instruction, the core compressed file can be read, decompressed and written into the memory so as to execute the starting of the core function. Reading the non-core compressed file, decompressing and writing the non-core compressed file into the memory so as to execute the starting of the non-core function. Therefore, the core compressed file is preferentially read from the flash area and written into the memory, the read time consumption of the flash area is reduced, and the core function can be quickly started.
Optionally, as a possible implementation manner, the core function start may be completed by reading the core compressed file, decompressing, and writing into the memory. After the core function is started, reading the non-core compressed file, decompressing and writing the non-core compressed file into the memory for execution so as to execute the starting of the non-core function, thereby finishing the starting of the whole image file.
Or, as another possible implementation, when the core compressed file and the non-core compressed file are stored in different Flash areas, the non-core compressed file may be read while the core compressed file is read, the core compressed file is decompressed and written into the memory to execute the start of the core function, and the non-core compressed file is decompressed and written into the memory to execute the start of the non-core function. Therefore, the whole starting speed of the operating system can be accelerated on the basis of quickly starting the core function.
The method for compiling the image file, provided by the embodiment, classifies and sorts all target files on which the complete image file depends in advance, and modifies the link script based on the sorted information to re-lay the complete image file, so that link disorder caused by change of a link mode can be avoided while compiling the newly laid complete image file. The rearranged complete mirror image comprises a front-end core function mirror image and a rear-end non-core function mirror image, and the size ratio of the core function mirror image is very small, so that the core function mirror image is read from a Flash area to an internal memory in the subsequent reading process, and the starting time of the complete core function is greatly reduced.
In addition, as the core function mirror image and the non-core function mirror image belong to a complete mirror image, resources can be shared without additional synchronous work. Therefore, based on the scheme, the core function mirror image of the front end is started first and then the non-core function mirror image of the rear end is started, so that the method is almost indistinguishable from the method of directly starting a complete mirror image, and the problem of complex process or resource waste does not exist.
