基于单片机的C语言与汇编语言的混合编程

The Mixed Programming of C51 and Assembly Based on the Singlechip

当前,单片机的应用程序主要是由C语言编写,而汇编语言直接面向底层硬件,能提高系统的准确性与效率。为了兼顾二者优点,可以采用混合编程的方式来编写单片机的应用程序。本文简单介绍了C51和汇编的2种混合编程方式,并通过具体范例说明了混合编程的步骤与注意事项。

At present, the application program of SCM is mainly written by C language, and the assembly language directly faces the underlying hardware, which can improve the accuracy and efficiency of the system. In order to take the advantage of the 2 programming languages, we can use mixed programming to write the application program on the singlechip. This paper introduces two kinds of mixed programming methods of C51 and assembly, and explains the steps and matters needing attention for mixed programming through the examples.
