Problems solved by technology

[0002] For beginners, computer assembly language is difficult to understand, and the data changes in registers, memory, pointers or bit memory during program operation are not intuitive, which is not conducive to understanding and memory
[0003] Previously, although there was a similar data analysis process on the assembly language development software platform, it has not been consciously sorted out and clearly proposed as an auxiliary tool in the analysis and writing of assembly language.

Embodiment Construction

[0022] The present invention is based on a table analysis method of computer assembly language. The table analysis method is a method of visually expressing a section of program written in assembly language in table form for auxiliary analysis. A specific example provided in Table 1 is used as a demonstration below for illustration.

[0023] The program first stores a 16-bit unsigned number 5677H in unit R6R7 of the register, and stores two other 16-bit unsigned numbers 1354H and 3A21H in unit R2R3 and R4R5 respectively. Afterwards, subtract the 16-bit unsigned data stored in the R2R3 unit and the R4R5 unit from the 16-bit unsigned data stored in the R6R7 unit, and leave the difference in the R6R7 unit. Using the relevant accumulator A, registers R2~R7, etc. used by the data flow when the program is running, analyze the program with the method of list, as shown in Table 1 below.

Abstract

The invention relates to an auxiliary analyzing device and an auxiliary analyzing method of a computer assembly language. The auxiliary analyzing device is provided with a controller, an input device, a display device and a program analyzer. The analyzing method comprises the following steps of: writing or leading in a program programmed by an assembly language and analyzing with the program to send out an instruction, an operation code and a data unit, and a change situation of a data flow; and displaying a matched table according to the output to analyze. The row and array quantities of the table are respectively and flexibly arranged according to quantities of instructions of the program and according to the quantities of data units including registers, memories, indicators, bit memories and the like. The data can be filled into corresponding data unit cells only when the data is changed, and the flow change state of the data is clear, so that the data is convenient to understand when the assembly language is analyzed or assembled, and the device and the method are time-saving and labor-saving.

Description

technical field [0001] The invention relates to an auxiliary analysis device and analysis method of computer assembly language, which is helpful for analyzing or writing computer assembly language. Background technique [0002] For beginners, computer assembly language is difficult to understand, and the data changes in registers, memory, pointers or bit memory during program operation are not intuitive, which is not conducive to understanding and memory. [0003] Previously, although there was a similar data analysis process on the assembly language development software platform, it has not been consciously sorted out and clearly proposed as an auxiliary tool in the analysis and writing of assembly language. Contents of the invention [0004] The purpose of the present invention is to provide an auxiliary analysis device and analysis method of a computer assembly language, which intuitively embodies the assembly language instructions, operands, data streams, etc. in the f...
