摘要
IEEE1394作为一种高性能串行总线标准,具有体积小,价格低廉,传输速率高,支持同步和异步两种数据传输模式,支持即插即用和热插拔,拓扑结构灵活,为外设提供电源,支持点对点传输等特点,在未来的PC产品中将有很大的应用空间。着重探讨1394协议、电源管理、基于1394的硬盘接口电路,对多功能接口电路的理论进行了初步设想。
IEEE1394 is a high performance serial bus standard with small size,low cost, high transfer rate, supporting synchronous and asynchronous data transfer mode and plug - play and hot - swappable. And it also has flexible topology to provide power for peripherals and to support point to point transmission, which should be in extensive use for PC products in the future. The exploration of 1394 protocol,power management, 1394 -based hard disk interface circuit,and a preliminary plan for the multi - functional interface eireuit theory are discussed.
