汇编语言的机器代码生成效率高、执行速度快，但可读性却并小强 而c语言的可读性和可移植性却远远超过汇编语言，用c语言开发中大型软件的周期要比用汇编语言短很多，但c语言很难解决高时效性等代码编写的问题，此时便可利用汇编语言来实现本文便是针对这一问题.详细介绍了单片机c语言与汇编语言混合编程的实现法。

-High machine assembly language code generation efficiency, fast execution, but readability but did little strong　and c language readability and portability is far more than assembly language, using c language development cycle than in large-scale software many short assembly language, but the language is difficult to solve the problem of high c timeliness and other coding, in which case you can use assembly language to implement this article is to solve this problem. Details of the SCM c language and assembly language programming mixed realization method.
