嵌入式系统中基于PCI的32位I0编程研究

32 bit I0 programming based on PCI in embedded system study

嵌入式系统在现代生活中应用广泛,32位I0设备和PCI技术已成为主流,所以对于嵌入式系统中基于PCI的32位I0编程研究非常有意义。针对很多设备的嵌入式系统中无编程环境的限制,本文选用无平台限制的BorlandC3.1编程环境。本文详细论述了在该环境中实现嵌入式系统中基于PCI的32位I0编程,包括:在C语言中嵌入汇编代码实现32位I0编程的原理和实现函数;获取PCI设备的I0基址和中断类型号的原理和实现流程图:用实验方法验证本文研究的正确性。

Embedded system is applied in modern society more and more widely,32 bit I0 device and PCI technology have become even more popularly,so it's meaningful to study the 32 bit I0 programming based on PCI in embedded system Because there is no programming environment in embedded system in many devices,the thesis chooses BorlandC3.1 which is no limitation for operation system.The thesis discusses the 32 bit I0 programming based on PCI in embedded system in the environment,the thesis includes:the principle and implementation function of 32 bit I0 programming by embedding assemble codes in C codes;the principle and processing diagram of getting the I0 base addresses and interrupting number of PCI device;the correctness of the topic study proved by the experimental method.
