However, in the related art, the chiplet needs to transfer a large amount of data each time an application is loaded, and thus the chiplet operates inefficiently.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a chip operation method according to an embodiment of the present disclosure. The chip operation method can be applied to electronic equipment. The flow of the chip operation method can comprise the following steps:

In the embodiment of the application, the system information related to the operating system is distinguished from the running information of the application program related to the application program, the second chip firstly receives the system information sent by the first chip, and loads the system information to normally run the operating system, the system information at this time does not contain a specific application program and only contains an operating system code and an application program management code, wherein the application program management code is mainly used for requesting and switching the application program.
In 102, based on the operating system, the second chip sends first request information to the first chip, where the first request information is used to request to obtain operation information of the first application.
In the running process, when the required application program needs to be loaded, for example, when the first application program needs to be loaded, the second chip may send first request information to the first chip, where the first request information is used to request to acquire the running information of the first application program.
The second chip may encapsulate the specific first application name and the code of the requesting application as the first request information, and send the first request information to the first chip to wait for the response from the first chip.
It can be understood that when the second chip needs to load different application programs, different request information of the first chip is correspondingly sent.
In 103, the second chip receives the running information of the first application program returned by the first chip.
After receiving the first request information of the second chip, the first chip unpacks and identifies the code of the request application program, and identifies that the request application program is the first application program, finds the corresponding running information of the first program and sends the running information to the second chip, wherein the running information of the first application program can be a compiled ELF file.
It should be noted that the ELF file may be an object file generated after compiling different application program codes and an executable file generated after linking, the ELF file may be compiled and generated by a third-party device, different application programs are compiled and generated correspondingly, the third-party device may be a computer, a server, or other device, and the first chip stores the compiled ELF files corresponding to different application programs.

According to the embodiment of the application, the system information related to the operating system is distinguished from the running information of the application program related to the application program, the second chip only needs to load the system information once to normally run the operating system, and the second chip does not need to reload the system information when the application program is required to be loaded in the running process, and only needs to load the running information of the application program as required, so that the second chip does not need to be reset, the data transmission of redundant system information is reduced, and the running efficiency of the second chip is improved.
Referring to fig. 2, fig. 2 is another schematic flow chart of a chip operating method according to an embodiment of the present disclosure, where the chip operating method may be applied to an electronic device, and the flow chart may include:
in 201, the second chip receives the system information sent by the first chip, and runs an operating system according to the system information;
in the embodiment of the application, the electronic device comprises a first chip and a second chip, the operating performance of the second chip is smaller than that of the first chip, and the electronic device can run more refined tasks by using double chips, for example, the first chip can run tasks with high performance requirements and run compute-intensive tasks; the second chip may be used to run a real-time operating system, such as to perform some display tasks.
In the embodiment of the application, the system information related to the operating system is distinguished from the running information of the application program related to the application program, the second chip firstly receives the system information sent by the first chip, and loads the system information to normally run the operating system, the system information at this time does not contain a specific application program and only contains an operating system code and an application program management code, wherein the application program management code is mainly used for requesting and switching the application program.
The system information can be compiled, generated and stored in the first chip by the third-party device, and sent to the second chip by the first chip.
In 202, based on the operating system, the second chip sends first request information to the first chip, where the first request information is used to request to obtain operation information of a first application program;
in the running process, when the required application program needs to be loaded, for example, when the first application program needs to be loaded, the second chip may send first request information to the first chip, where the first request information is used to request to acquire the running information of the first application program.
The second chip may encapsulate the specific first application name and the code of the requesting application as the first request information, and send the first request information to the first chip to wait for the response from the first chip.
It can be understood that when the second chip needs to load different application programs, different request information of the first chip is correspondingly sent.
In one embodiment, the second chip sends the first request message to the first chip through a mailbox interface. The mailbox interface is a hardware mechanism for data transmission among multiple processors, and can be used for transmitting address or instruction data with small data volume, but the transmission efficiency is higher.
In 203, the second chip receives the running information of the first application program returned by the first chip.
After receiving the first request information of the second chip, the first chip unpacks and identifies the code of the request application program, and identifies that the request application program is the first application program, finds the corresponding running information of the first program and sends the running information to the second chip, wherein the running information of the first application program can be a compiled ELF file.
It should be noted that the ELF file may be an object file generated after compiling different application program codes and an executable file generated after linking, the ELF file may be compiled and generated by a third-party device, different application programs are compiled and generated correspondingly, the third-party device may be a computer, a server, or other device, and the first chip stores the compiled ELF files corresponding to different application programs. Specifically, the third-party device derives the symbols required to be used by the running information of the on-demand application program, where the running information of the on-demand application program may also be referred to as a dynamic module, and the symbols required to be used include: code segments, function names, common addresses, etc., export symbols to designated sections that require space to be allocated in the linking script for subsequent dynamic modules to relocate to these symbols. The header file of the derived symbols needs to be generated in the system information so that the dynamic module can find the symbol declaration when compiling, but the symbols belong to undefined symbols, and the dynamic module calls the API interface in the system information when compiling, so that the system information needs to derive the API interface exposed to the dynamic module to a certain position of the symbol table so that the dynamic module can find the symbols at the position when actually loading the dynamic module, and the header file is derived so that the dynamic module can be compiled normally to generate the ELF file.
In the operation process of the second chip, when a specific application program needs to be loaded, the second chip communicates with the first chip to send request information, so that the operation information of the required application program is acquired.
In one embodiment, the second chip receives the running information of the first application program returned by the first chip through a serial peripheral interface. The serial peripheral interface is a high-speed full-duplex synchronous communication bus, and can be used for transmitting data with larger data volume.
In 204, the second chip runs the corresponding first application program according to the running information of the first application program.
After receiving the operation information of the first application program sent by the first chip, the second chip may operate the corresponding first application program according to the operation information of the first application program. After receiving the ELF file corresponding to the first application program sent by the first chip, the second chip analyzes the ELF file, after removing the information header, the code segment information of the first application program is reserved, and the second chip analyzes and relocates the address information of the code segment information (ELF format) of the first application program, so that the first application program can be operated.
Specifically, after receiving the ELF file corresponding to the first application program sent by the first chip, the second chip checks whether the file is in the ELF format, including checking an ELF header and an ELF field, where the ELF file is divided into a plurality of segments, such as PT _ LAOD, PT _ NULL, PT _ dyanic, and so on. The PT _ LAOD includes information that is really loaded to the memory for operation, and may only focus on the segment of the PT _ LAOD, record the entry point of the corresponding dynamic module, and find the segment that needs to be relocated and its corresponding symbol table according to the segment table (segment header table) of the ELF file. The dynamic module uses the symbol to link to the position of the characteristic, adds variable in the link script to record the initial address and the end address of the position, searches the symbol in the symbol table in the two addresses, if found, relocates the symbol in the symbol table; if the symbol is not found, the dynamic module uses the symbol which is not derived by the system, and then error reporting processing is carried out. If the search is completed, a thread is newly created, and the execution is started from the entry point of the dynamic module.
In the operation process of the second chip, when a new application program needs to be switched to operate, for example, when the second application program needs to be operated, the second chip sends second request information to the first chip, wherein the second request information is used for requesting to acquire operation information of the second application program; the second chip receives the running information of the second application program returned by the first chip; and the second chip switches and operates the corresponding second application program according to the operation information of the second application program.
Specifically, when the second chip needs to switch to operate the second application program in the operation process, the second chip may encapsulate a specific second application program name and a code of the request application program as second request information and send the second request information to the first chip, the first chip receives the first request information of the first chip, unpacks and identifies the code of the request application program, identifies the request application program as the second application program, finds out the corresponding operation information of the second application program and sends the operation information of the second application program to the second chip, and the operation information of the second application program may be a compiled ELF file. And after receiving the ELF file corresponding to the second application program sent by the first chip, the second chip analyzes the ELF file to run the second application program in a switching way.
In the embodiment of the application, the second chip only needs to load the system information once to normally operate the operating system, and when a new application program needs to be switched to operate in the operating process of the second chip, the system information does not need to be reloaded, and only the operating information of the new application program needs to be loaded as required to operate the new application program, so that the second chip does not need to be reset, redundant data transmission is reduced, and the operating efficiency of the second chip is improved.
In 205, when the first application program calls the picture data in the operation, the second chip sends the picture request information corresponding to the picture data to the first chip.
In the embodiment of the application, the running information of the application and the data resource of the application are separately transmitted, and the data resource is, for example, a picture data resource. In the embodiment of the application, the running information of the application program and the picture data resource are separately transmitted, on one hand, the second chip can quickly receive the running information of the application program to quickly run the application program, and does not need to occupy a large memory of the second chip; on the other hand, the second chip may request the required picture data according to the actual operation requirement of the application program in the operation process of the application program, and does not need to receive all the picture data corresponding to the application program at the same time, so the second chip may also quickly receive the required picture data, and the memory space of the memory of the second chip is limited, if all the picture data are received, a large amount of memory space of the second chip is occupied, which may cause insufficient memory space of the second chip, which may affect the normal operation of the application program. For example, when the resolution of the display screen of the electronic device is high, the bit information of the picture to be displayed is large, but the normal display of the picture is affected due to the insufficient storage space of the memory of the second chip.
In this embodiment of the application, when the second chip needs to run the first application program, the running information of the first application program is received, so that the first application program can be normally run, wherein the picture data resource in the running information of the first application program is empty. Specifically, a variable of the picture data in the application program may be directly assigned with a null value, for example, the variable example is necessary information of the picture data that needs to be displayed on the second chip, and example. Since the application program contains many such picture data, if the second chip receives all the picture data, the application program occupies a large amount of memory, and here, example. data is directly assigned to be null, and when the second chip needs to operate, the picture data is transmitted, for example, by the following software codes:
Struct img_info example＝{
.type＝xxx,
.w＝255,
.h＝255
.data＝NULL}
when the second chip needs to call the picture data in the running process, the second chip sends the picture request information corresponding to the picture data to the first chip. The picture request information includes a specific application program and a required unique code of picture data.
It should be noted that the second chip may request one piece of picture data at a time, or may request multiple pieces of picture data at a time, and when multiple pieces of picture data need to be requested, the picture request information may include unique codes of multiple pieces of picture data.
In 206, the second chip receives the picture data returned by the first chip.
After receiving the picture request information of the second chip, the first chip unpacks the picture request information and identifies the picture data of which application program is specifically requested and which picture data is specifically requested, finds the corresponding picture data and sends the corresponding picture data to the second chip, so that the second chip receives the picture data returned by the first chip.
In an embodiment, the second chip receives the picture data returned by the first chip through a serial peripheral interface, and as can be understood, the data volume of the picture data is relatively large, so that a smooth transmission of the picture data can be ensured by using a transmission mode of the serial peripheral interface.
It should be noted that, when the application program of the second chip needs to load new picture data during the running process, the above steps 205 to 206 are repeated.
In 207, the second chip stores the picture data in a memory, and manages the picture data by using a linked list.
The second chip may store the received picture data in the memory, and manage the received picture data using the linked list.
After the picture data received by the second chip is stored in the memory, the address information can be given to a resource variable, such as example. When the application program needs to call the existing picture data in the memory, the application program can be directly called without requesting the picture data from the first chip.
In 208, when the storage space of the memory is insufficient, the picture data corresponding to the linked list is managed by using a page replacement algorithm, so as to delete the picture data stored in the memory for the longest time and not used.
When the storage space is smaller than or equal to a preset threshold value, the page replacement algorithm can be utilized to manage the picture data corresponding to the linked list so as to delete the longest unused picture data stored in the memory and release the storage space of the memory of the second chip, so that more picture data required by the application program at present can be received, normal operation of the application program at present and normal display of the picture data of the application program at present are ensured, and the problem of insufficient storage space of the memory of the second chip is solved.
It should be noted that other algorithms for managing the memory may also be used to manage the picture data, and the application is not limited herein.
According to the embodiment of the application, the system information related to the operating system is distinguished from the running information of the application program related to the application program, the second chip only needs to load the system information once to normally run the operating system, and when a new application program needs to be loaded or switched in the running process, the second chip does not need to load the system information again, only needs to load the running information of the required application program as required, and therefore the currently required application program can be normally run. Therefore, the second chip does not need to be reset, and the transmission of redundant system information is reduced, so that the operating efficiency of the second chip is improved.
Furthermore, the operation information of the application program and the data resources of the application program are transmitted in a classified manner, and the data resources are image data resources, on one hand, the second chip can quickly receive the operation information of the application program to quickly operate the application program, and does not need to occupy a large memory of the second chip; on the other hand, the second chip can request the required picture data according to the actual operation requirement of the application program in the operation process of the application program, and does not need to receive all the picture data corresponding to the application program at the same time, so that the second chip can also quickly receive the required picture data and does not occupy a large amount of storage space of the second chip. In addition, in the embodiment of the application, when the second chip performs chain table management on the received picture data, and when the storage space of the memory is smaller than a preset threshold value, the picture data corresponding to the chain table is managed by using a page replacement algorithm to delete the picture data which is stored in the memory for the longest time and is not used, and the storage space of the memory of the second chip is released, so that the picture data which is currently required by more application programs can be received, the normal operation of the current application program is ensured, and the normal display of the picture data of the current application program is ensured, thereby effectively solving the problem that the storage space of the memory of the second chip is insufficient.
