Problems solved by technology

In summary, the configurable assembler described in this technology provides users with too complex and abstract description methods, which are difficult to grasp; each time an assembler with a different ISA is generated, it needs to be recompiled, which takes a lot of compilation time

Abstract

A user-description-based assembler and its implementation method in the field of computer technology, wherein: the ISA description module reads in the instruction set architecture information described by the user, and extracts ISA data from the user's description information to automatically configure structured information module; the structured information automatic configuration module organizes the data into structured ISA information and outputs it to the ISA information base management module; the ISA information base management module stores the structured instruction structure information into the memory, and will The ISA information is passed to the assembly function processing module; the assembly function module reads the assembly source file, and obtains the required ISA information from the ISA information database management module, which is used to process the assembly source file, and finally generates the corresponding binary code file. The present invention also provides the above-mentioned assembler generating method, which can conveniently and intuitively generate the assembler with corresponding assembler function according to the user's description of the ISA without repeated compiling.

Description

technical field [0001] The invention relates to a system in the field of computer technology and its implementation method, in particular to an assembler based on user description and its implementation method. Background technique [0002] The assembler is an important part of the compilation system, and its main function is to convert the source program written in assembly language into a binary form of the object file. The input to an assembler is an assembly language program, which can be the output of a compiler or a handwritten assembly language program. The output of the assembler is a binary object file. [0003] In the design and implementation of existing assemblers, different assemblers must be developed for different instruction set architectures (hereinafter referred to as ISA) to meet the requirements of different processors, so that when developing a new processor, it is necessary to Redevelop the corresponding assembler. Currently, assemblers are typically...
