摘要
本文论述一种四通道DMA通信板的硬件设计和软件编程。该通信板插在86/330A机箱内,用来管理双机之间的数据通信。86/330A的数据通信采用高级规程(HDLC)协议,采用DMA传送方式及RS-232接口标准。
This paper describes the hardware design and software programming of a 4 way DMA communitcation board which can be inserl in 86 / 330A computer, to manage the data communication betweon two computer. The data communication protocat of 86/330A computer obies the HDLC protocal, uses DMA transmission manner and RS-232 interface standard.
