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

The present invention provides a user description based assembler and a realizing method in the computer technology field, wherein, an ISA descriptor module reads in the user described instruction set system structure information, and picks up the ISA data from the user described information to an structured information auto-configure module; the structured information auto-configure module organizes the data into the structured ISA information for outputting into an ISA information base managing module; the ISA information base managing module deposits the structured instruction structure information in the EMS memory, and transfers the ISA information needed in the assembling process to an assemble function processing module. The assemble function module reads in the assemble source file, and obtains the needed ISA information from the ISA information base managing module for processing the assemble source file, and produces the corresponding file of a binary system code. The present invention also provides the producing method of the assembler, can describe the ISA according to users conveniently and intuitively, and can produce the corresponding assembler with assemble function instantly without repeated compilation.

Description

technical field [0001] The invention relates to a system in the field of computer technology and an implementation method thereof, in particular to a user-described assembler and an implementation method thereof. Background technique [0002] The assembler is an important part of the compilation system. Its main function is to convert the source program written in assembly language into the object file in binary form. The input of the assembler is the assembly language program, which can be the output result of the compiler or the handwritten assembly language program. The output of the assembler is a binary object file. [0003] In the design and implementation of the existing assembler, 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 new processors, it is necessary to Re-develop the corresponding assembler. Currently, the assemble...
