Description

Technical Field

[0001] This invention relates to an application migration method and system based on the Shenwei processor, belonging to the field of application migration technology. Background Technology

[0002] Currently, many domestic operating systems attempt to be compatible with multiple domestic processor architectures. However, the influence of each processor ecosystem is not the same, resulting in inconsistent application migration standards and varying amounts of code modifications. A unified standard has not yet been formed. Furthermore, the experience and knowledge of software developers have a significant impact on the efficiency of application migration.

[0003] Currently, domestic technology companies have developed supporting application migration platforms for the domestic processor architectures they use, in order to promote the porting of application software from various industries to their operating systems, which has greatly promoted the localization of application software. However, at present, none of the application migration platforms are applicable to Shenwei processors, and they cannot provide modification suggestions for Shenwei's self-developed instruction set for assembly, embedded assembly, and other code. Summary of the Invention

[0004] The purpose of this invention is to provide an application migration method and system based on the Shenwei processor. Addressing the challenges of complex software porting processes and high levels of expertise required by the Shenwei platform, this invention designs an algorithm for scanning architecture-related code based on coding rules, locates code blocks, analyzes code functions, generates modification suggestion reports, and finally visualizes the scanned data through a web page.

[0005] To achieve the above objectives, the present invention is implemented using the following technical solution.

[0006] On one hand, the present invention provides an application migration method based on the Shenwei processor, comprising: The source code package is initialized, the configuration file is parsed, the software dependencies of the source code package are determined, and the portability of the dependent software is determined by the software whitelist. Establish an assembly dictionary for the processor architecture, and design conditional compilation, embedded assembly, and vector extension keyword regular expressions based on the built-in macro definitions of the processor architecture; Scan the key files of the processor architecture, and scan the embedded assembly and full assembly code in the key files according to the assembly dictionary, and save the scan information to the evaluation report; The scan information is analyzed, and modification suggestions for the Shenwei processor architecture are obtained based on the correspondence between the processor architecture and the Shenwei processor architecture. The workload of application migration is evaluated based on the modification suggestions, and the analysis results are saved to the evaluation report. The evaluation report is rendered into HTML by a web server and returned to the client for user reference.

[0007] Optionally, the configuration file includes Makefile, spec, and control files.

[0008] Optionally, the processor architecture includes x86 and ARM architectures.

[0009] Optionally, the key files of the processor architecture include .c, .cpp, .h, .hpp and .S architecture-related files.

[0010] Optionally, the scanning information includes information such as the file where the scanned code is located and the number of lines of code.

[0011] Optionally, the workload assessment for application migration is based on the total number of lines of code to be modified in the modification suggestions, the ratio of full assembly to embedded assembly, and the total number of application codes. This assessment provides excellent guidance for application migration.

[0012] Secondly, the present invention provides an application migration system based on the Shenwei processor, comprising: The dependency analysis module is used to analyze the software support that the source code depends on for compilation and execution, and to determine the software that needs to be installed and adapted before compilation. The porting assistance module is used to scan architecture-related branches in the source code, locate code porting objects, parse conditional compilation, locate code blocks, and provide modification suggestions for assembly code based on instruction conversion dictionaries. The assessment report module is used to display the code items to be migrated and processing suggestions, count the number of files to be modified and the number of lines of code, and assess the workload required to migrate the software to the Shenwei processing platform.

[0013] Optionally, the evaluation report module includes detailed source code migration information and report display information; The detailed source code migration information includes a list of files to be modified, file display and comparison, and porting optimization suggestions; the report display information includes detailed information on dependency library files, statistics on files to be modified, a summary of lines of code modified, and workload assessment.

[0014] Thirdly, the present invention provides a computer-readable storage medium having a computer program / instruction stored thereon, which, when executed by a processor, implements the steps of any of the application migration methods based on the Shenwei processor described in the first aspect.

[0015] Fourthly, the present invention provides a computer device / equipment / system, characterized in that it comprises: Memory, used to store computer programs / instructions; A processor for executing the computer program / instructions to implement the steps of the application migration method based on the Shenwei processor as described in any of the first aspects.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: During the application migration process, this invention directly identifies the full assembly, embedded assembly, and other architecture-related code in the application software and provides modification suggestions for the Shenwei architecture, which greatly improves the efficiency of application migration and reduces the application migration time. During the application migration process, a comprehensive assessment is conducted based on factors such as the total amount of application code, the amount of code to be modified, and the varying levels of difficulty of the code to be modified. This provides a clear and intuitive representation of the workload required for the final application migration, offering excellent guidance for the process. By visualizing the scanned data through a web page, the efficiency of application migration is improved, the migration time is reduced, and a higher degree of automation can be achieved in migrating application software to Shenwei processors, thereby enhancing Shenwei's market competitiveness.

The workload of application migration is evaluated based on the modification suggestions, and the analysis results are saved to the evaluation report. The evaluation report is rendered into HTML by a web server and returned to the client for user reference.

[0020] Step 1: Initialize the source code package, parse the Makefile, spec and control files, check the compilation environment of the configuration file, analyze the pre-compilation and compilation scripts to determine the software dependencies of the source code package, and determine the portability of dependent software through the software whitelist.

[0022] Step 4: Analyze the scan information, obtain modification suggestions for the Shenwei processor architecture based on the correspondence between other architectures and the Shenwei processor architecture, and put them into the special software migration method library; evaluate the workload of application migration based on the modification suggestions, and save the analysis results to the evaluation report; the scan information includes information such as the file where the scanned code is located and the number of lines of code.

[0023] The assessment of application migration workload is based on the total number of lines of code to be modified in the modification suggestions, the ratio of full assembly to embedded assembly, and the total number of application codes. This assessment provides excellent guidance for application migration.
