Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like reference numerals generally refer to like parts or elements.
Fig. 1 illustrates a schematic structure of an external memory and an internal memory according to an exemplary embodiment of the present invention. As shown in FIG. 1, computing device 200 includes internal memory 230 and external memory 210, and is running an operating system 220. The invention is not limited in the nature of the operating system 220. The external memory 210 stores therein an application file 211 and a module file 212. The manner in which the external memory 210 stores the application files 211 and the module files 212 shown in fig. 1 is merely exemplary, and the present invention does not limit the number of application files and module files stored in the external memory 210.
The application file 211 may be implemented as an application file of any kind of application program, and the kind of application program and the type of application file are not limited in the present invention. According to one embodiment of the present invention, the application file 211 is compiled, assembled, linked, etc. by the operating system 220 to obtain an executable file of the application program, and finally loaded into the internal memory 230.
The module file 212 may be implemented as a module file of any kind of function module, and the function module may implement additional functions of an application program, and the present invention is not limited to the file type of the module file 212 and the kind of the additional functions of the implemented application program. The module file 212 may be an uncompiled file that is processed in advance when loaded into the internal memory 230, resulting in an executable file of the functional module that may be loaded into the internal memory 230. The module file 212 may also be implemented as a binary type file that is convenient to load directly into the corresponding location in the internal memory 230.
The module file 212 is previously constructed by a developer, and in order to implement additional functions in the application program, the module file 212 needs to be loaded into the internal memory 230, and in particular, needs to be stored in the internal memory 230 at a corresponding location where an executable file of the application program is stored. After the module file 212 is deployed to the corresponding position, the module file 212 is transparent to the application program, the application program does not sense and use the module file 212, and the operating system 220 directly calls the module file 212 to construct a function module, so that the additional function of the application program is realized.
When storing an executable file of an application, the internal memory 230 allocates memory space for the executable file. The memory space allocated by the internal memory 230 includes a plurality of different memory segments, and the executable files are stored in the internal memory 230 in the form of the memory segments. The internal memory 230 divides the storage space into memory sections including a heap section, a stack section, an initialized data section, and an uninitialized data section. The memory segment is divided in the internal memory 230 according to the first memory information by determining the first memory information according to the file information of the application executable file when the operating system creates the process.
The initialized data section is used for storing initialized global variables in the application program, and is static memory allocation. If the module file to be inserted into the application program needs to be used for a new data, and the data needs to be given an initial value, the module file needs to be inserted into the initialization data section, so that the data to be initialized in the module file can be initialized, the module file can be normally loaded, and the additional function of the application program can be realized.

Fig. 3 shows a flow diagram of an application running method 300 according to an exemplary embodiment of the invention. The application running method 300 of the present invention is executed in a computing device and is further adapted to be executed in a computing device 200 as shown in fig. 1. As shown in fig. 3, the instruction execution method 300 starts with step S310, and an executable file of an application program is generated according to the application file 211.
The application file 211 stored in the external memory 210 cannot be directly loaded into the internal memory 230 without being preprocessed. According to one embodiment of the invention, application file 211 requires steps such as compiling, assembling, and linking it by operating system 220 to obtain an executable file for the application program. The steps and methods by which the operating system 220 pre-processes the application file 211 are not limited by the present invention.
Subsequently, step S320 is performed to determine, according to the executable file of the application program, first storage information stored in the internal memory 230 by the application program, the first storage information including first section information of the initialization data section allocated in the internal memory 230.
The first storage information stored in the internal memory 230 by the application program includes section information of a plurality of memory sections. The divided memory sections in the internal memory 230 include a heap section, a stack section, a code section, an initialized data section, and an uninitialized data section. The memory segment is divided in the internal memory 230 according to the first memory information by the operating system 220 when creating a process, which determines the first memory information according to the file information of the application executable file. The initialization data section stores initialized initialization data in the executable file, including initialized global variables in the application program.
When determining the first storage information stored in the internal memory 230 by the application program according to the executable file of the application program, the first section size and the first alignment information of the initialization data section allocated in the internal memory 230 are determined according to the executable file. Specifically, determining the size of a first section according to initialization data in an executable file, namely how many initialized global variables exist in an application program; the application alignment of the executable file stored in the internal memory 230 is then determined as the first alignment information based on the processor's pointing pattern decision. The first alignment information indicates from which alignment boundary the start address of the initialization data segment should start (e.g., 2, 4, 8, 32 byte alignment, etc.) it determines the start position of the initialization data segment, and is specifically determined by the instruction of the processor.
First section information of the initialization data section is then generated according to the first section size and the first alignment information, the first section information including the first section size and the first alignment information.
And generating first storage information according to the first section information, and taking the first section information of the initialized data section and the section information of other data sections as the first storage information. Other data sections include heap sections, stack sections, code sections, and uninitialized data sections.
Subsequently, step S330 is performed to generate second section information of the initialization data section according to the first section information and the module file 212.
Fig. 4 illustrates a schematic diagram of inserting a module file into an initialization data section according to an exemplary embodiment of the present invention. As shown in fig. 4, the module file 415 is inserted into the initialization data section 416, and the section information of the initialization data section 416 is the first section information calculated according to steps S310 and S320. When loading the executable file in the internal memory 230, the storage space required for storing the executable file is increased; specifically, memory space is reserved for module file 415 in initialization data field 416. The insertion of the module file 415 in the initialization data segment 416 can be achieved by adding reserved storage space, which is not itself in the storage space required for storing the executable file. The module file 415 is the same as the module file 212 in fig. 1, but if the module file 212 cannot be directly stored in the internal memory 230, the module file 212 needs to be preprocessed to obtain the module file 415.
After inserting the module file 415 into the initialization data section 416, an initialization data section 426 is obtained. Initialization data segment 426 changes in size and starting position from initialization data segment 416, and the segment information of initialization data segment 426 needs to be recalculated to obtain the second segment information.
Fig. 5 illustrates a flowchart of generating second section information according to an exemplary embodiment of the present invention. As shown in fig. 5, first section information is acquired, a second section size is generated according to the first section size and the module file 212, and when the second section size is generated, the first section size and the file size of the module file 212 are added to obtain the second section size.
Next, second alignment information is generated according to the first alignment information and the module file 212, wherein the first alignment information includes an application alignment manner, and the application alignment manner refers to which alignment boundary the start address of the initialization data section should start, and determines the start position of the initialization data section. When generating the second alignment information, the module alignment is generated according to the application alignment, from which alignment boundary the initialization data segment starts, and from which alignment boundary the module file 212 starts, so as to ensure that the module alignment of the module file 212 in the internal memory 230 is the same as the application alignment of the executable file in the internal memory 230.
According to one embodiment of the invention, the initialization data segments are aligned in 32-bit bytes, and then the module file 212 is also aligned in 32-bit bytes.
And then generating second alignment information according to the application alignment mode and the module alignment mode. The second alignment information includes an application alignment mode and a module alignment mode.
And generating preset section information of the initialization data section according to the second section size and the second alignment information. The preset section information includes a second section size and second alignment information.
Then, whether the module file is stored across page boundaries or not is determined when the module file is stored in the internal memory according to the generated preset section information. The internal memory uses a memory paging mechanism when storing data, and stores the data in a memory page mode. And if the module file is not stored across the page boundary, taking the preset section information as second section information. If the module file is stored across the page boundary, the occupied section is added before the storage position of the module file, so that the module file is not stored across the page boundary, and the processor can conveniently read and process transparent data from the internal memory. And finally generating second section information according to the added occupied section and preset section information. And storing the module file after the occupied zone, and then re-determining the second zone size and second alignment information according to the size of the occupied zone, and generating second zone information according to the modified second zone size and second alignment information.
Subsequently, step S340 is performed to generate second storage information from the second section information and the first storage information. And when the second storage information is generated, combining the second section information of the initialized data section with the section information of other data sections in the first storage information to obtain the second storage information. Other data sections include heap sections, stack sections, code sections, and uninitialized data sections.
Subsequently, step S350 is performed to load the executable file of the application program and the module file 212 into the internal memory 230 according to the second storage information. When the executable file of the application program and the module file 212 are loaded into the internal memory 230, the initialization data section is first allocated in the internal memory according to the second storage information.
When the initialization data section is allocated, the size of the initialization data section is determined according to the size of the second section, and the memory page head address for storing the initialization data section, the starting address for storing the module file in the memory page where the initialization data section is located and the starting address for storing the application file are determined according to the second alignment information.
As shown in fig. 4, the allocated initialization data segment 426 is increased in size relative to the calculated initialization data segment 416, and the increased reserved memory space is used for storing the module file 415. Initialization data for the application to be stored by the original initialization data section 416 is still stored in the initialization data section 426.
Then, an initialization flag is added to the start address stored in the module file, so that the module file is inserted according to the initialization flag. When the initialization identifier is added, a data address table is constructed, and the data address table stores one or more data address rows. The data address table is used for determining whether the data needs to be initialized and retrieving the initial position of the initialized data storage so as to store the initialized data in the corresponding initial position.
And then adding the memory page head address of the internal memory storage module file, the initial bit address stored by the module file and the section type in the data address row, wherein the section type is an initialized data section. And judging whether the initialization of the data is needed in the memory page according to whether the memory page head address and the section type of the data address line storage module file exist. If the data is initialized, the initialization data is stored according to the initial bit address stored in the module file.
Also included in the computing device is a processor (not shown in fig. 1). The processor reads and processes data from the internal memory. When the data section is allocated, only the section for data storage is allocated, the initialization identification of the module file is set, and the storage of the application file and the module file is not completed. The processor accesses and acquires the module file and the application file according to the starting address stored in the module file and the starting address stored in the application file. The processor checks whether the corresponding file is stored in the corresponding position according to the storage address of the file, the corresponding file has actual memory, and if the corresponding file is not stored in the corresponding position, the page fault abnormality can be thrown out.
The step of loading the executable file into the internal memory according to the second storage information includes the step of writing the initialization data of the executable file into the initialization data section when the processor generates a page fault due to the fact that the initialization data section does not store the relevant data. When an executable file of the application program is generated, initializing data which is needed to be initialized by the application program to obtain initialization data in the executable file.
And then, when the module file is loaded into the initialized data section according to the second section information of the initialized data section of the second storage information, firstly, inquiring whether a data address row comprising the memory page head address exists in a data address table according to the memory page head address stored in the internal memory of the module file. One or more rows of data addresses are stored in the data address table. And if the data address line comprising the memory header address is queried, determining the sector type of the data address line so as to determine whether the data initialization operation is required.
