利用汇编程序实现I/O端口操作技术的研究

Realizing of port read-write by built-in assembler in Delphi

介绍了如何在Delphi中通过嵌入汇编程序在混合编程时如何传递参数 ;编写了I/O端口操作函数 ,并在此基础上研究了在数据采集的应用中如何根据具体硬件配置 ,用数据采集方法编写各种数据采集的汇编程序 .

How to program function on port read-write by built in assembler in Delphi is introduced in this thesis. By this method many kinds of functions on data sampling can be programmed in terms of specific hardware condition and data sampling method.
