Keil C51中C51程序与汇编程序的接口方法

C语言程序与汇编语言程序的相互调用可视为函数的调用,只不过此函数是采用不同语言编写。在C和汇编程序的相互调用中,要求汇编程序必须服从Keil C51中对函数名的转换规则,同时也要弄清C函数的参数传递规则,通过实例详细介绍Keil C51中C51程序与汇编程序相互调用以及汇编程序与C51程序相互调用时的接口建立方法,并给出在不同的应用中对接口进行简化的方法。

Interface Method of C51 in Keli C51 and Assembler

The interactive transfer of C Language Program and Assembly Language Program could be regarded as functional transfer.In interactive transfer of C and assembler,it is required that assembler should obey the transfer rule of function name in Keli C51.Meanwhile,it is also required to understand parameter transfer rule of C function.With actual examples,this paper explains the interface method of interactive transfer between Keli C51 abd assembler,between assembler and C51,and the simplification method for interfaces in various applications.
