摘要
分析了超大规模集成电路(VLSI)专用芯片COM1553 B的功能和接口信号,并论述用COM1553 B设计总线接口单元(BIU)的方法。给出结构框图和直接存储器存取(DMA)方式交换信息的设计思想。按此方法设计的BIU,具有通用性好、可靠性高和良好的软件接口的特点。
The function and interface signal of the special Very Large Scale Integration chip COM 1553 B are analysed.The method of designing Bus Interface Unit by using COM1553 B is described.It also presented the block diagram and design procedures by using Direct Memory Access for exchanging information.Finally,the character(universality,high reliability and good software interface) of the BIU,which was designed by using the method,is given.
