A method and device for code conversion from assembly language to high-level language

Abstract

The invention provides a method and a device for code conversion from assembly language to high-level language. The method includes: acquiring assembly instructions; S100, creating output text in the high-level language, and using the high-level language codes to simulate a processor operation environment corresponding to the assembly instructions; S200, searching high-level language functions corresponding to the assembly instructions, and creating a table of mapping relation between the assembly instructions and the high-level language functions; S300, traversing the assembly instructions, extracting a data item including instruction addresses, operators and a plurality of opcodes; S400, analyzing all the functions, automatically generating and outputting declarations of the functions to the output text in the high-level language; S500, generating a corresponding high-level language code for each function, and outputting the code to the output text in the high-level language; and S600, adding auxiliary codes allowing for successful execution of the high-level language codes in the output text. The assembly instructions can be converted into the high-level language efficiently and correctly by the method.

Description

technical field [0001] The invention belongs to the field of computer software programming, and in particular relates to a disassembly technology of the underlying software of a chip system. Background technique [0002] Software on chips such as SOC and DSP is generally developed in high-level languages ​​such as C and C++. On the development machine, through the special compiler of the chip, the high-level language is compiled into binary machine instructions, and then the binary machine instructions are loaded into the memory of the chip, and then the corresponding compiler can be used to convert the machine instructions into corresponding assembly language. [0003] Therefore, to disassemble the software on a particular chip is to restore these machine instructions to a high-level language. Regardless of whether it is converted using machine instructions or an assembly language written directly by humans, the assembly language needs to run on a specific processor, and ...

AI Technical Summary

Problems solved by technology

Regardless of whether it is converted using machine instructions or an assembly language written directly by humans, the assembly language needs to run on a specific processor, and the assembly language cannot be transplanted to run on other processors. Moreover, when the amount of code is large Assembly language is hard to read when

In the case that the high-level language codes corresponding to these codes cannot be obtained, there is an urgent need to convert the assembly language of the chip into a general-purpose high-level language in many cases, so an efficient method is needed to convert the assembly language into a high-level language.
