Abstract: With the increasing speed of execution of computer various embedded processor,assembly language,which is the most efficient and contributes to the development of computer technology,has been replaced by other “advanced” languages.However,the advantages of assembly language are not only the efficiency of its implementation.As a hardware programming language between hardware and software,it has obvious advantages in electrical professional students to master professional skills and improve their practical ability.This paper introduces the assembly language training and training in the course of the electronic design competition training,so that all the students' abilities can be invisible in the process and have achieved good teaching effect.Practice has proved that assembly language has the inherent advantages in cultivating students' practical ability and macroscopic thinking ability.
