局域网实时通讯与中断机制

LOCAL NETWORK REAL-TIME COMMUNICATION AND INTERRUPT MECHANISM

各种类型的实时通讯都与中断方式紧密相关,在研究网络通讯的基础上,本文对微机中断结构及其上网以后的变化作了讨论,阐述了修正中断机制的一些问题,提出了实中断向虚中断过渡的概念。事实上,这些方法用于实时通讯,特别是通用微机局域网实时通讯中,显示出它的可靠性和可行性。

The different types of the real -time communication are closed with the interrupt - way. On the base of researching network communication, the paper discusses the interrupt construction of the microcomputer and the changes after it connected with the network, states some problems of modifying the interrupt, gives the concept of the real-virtual. Actually, these methods are reliable and realizable in the real - time communication, especially, in the network communication.
