Problems solved by technology

However, since the change of some local parameters may only affect a certain part of the output process, and it is interspersed throughout the long output process, it is difficult for programmers to find the part of the output difference, causing programmers to conduct multiple simulations to observe the output results , will waste a lot of time and energy of programmers, and this method is not conducive to repeated observation results, which greatly affects the efficiency of learning and development

Abstract

The invention relates to an operation effect comparison system of an embedded system with different parameters, the operation effect comparison system is characterized by comprising an embedded systemsimulation module; a video recording mechanism; and a video comparison module. A difference video is obtained after the system is used. Therefore, a user can visually observe the influence of the twodifferent parameter values on output in the program, the whole output process does not need to be observed for a long time, the user does not need to repeatedly compare and observe the two effect output files to find a difference part, and the system has auxiliary significance for development of teaching and training and can also be used for effect evaluation in the actual development process.

Description

technical field [0001] The invention relates to the technical field of embedded system learning and development, in particular to an embedded system hardware simulation result comparison system. Background technique [0002] Embedded system is currently one of the hottest and most promising IT application fields. In the process of learning and developing embedded systems, programmers often need to explore the impact of a specific parameter in the program on the output. Hardware emulation is one of the most intuitive, effective and easy-to-implement methods. Programmers will observe the results of two different parameter simulations, and according to the difference in output before and after the simulation results, infer the role of the parameter in the program, and then help programming and maintenance. However, since the change of some local parameters may only affect a certain part of the output process, and it is interspersed throughout the long output process, it is di...
