摘要
1394总线具有高速、灵活和可扩展性等特点,已经有越来越多的设备开始使用这种总线,而RS422总线是一种相对成熟并且应用较多的总线,其特点灵活、方便、可靠。因此根据在研项目,为了实现新老总线之间正常、稳定的通讯,基于FPGA技术设计并实现了1394总线与RS422总线桥。经过实践论证,在一定条件下,1394总线与RS422总线可以进行正常、稳定的通讯。文中着重介绍了1394总线与RS422总线桥的设计方法,着重通过1394总线与RS422总线桥的逻辑架构和总线桥的数据流两个方面介绍了1394总线与RS422总线桥的设计思路。
The more and more devices begin to use 1394 Bus because of its characters of high speed, flexibility and expansibility. RS422 has been considered as a kind of flexible, convenient and reliable bus, also has been used in serial fields as RS422 Bus is one of more mature and widely used bus. That＇ s why the bus bridge between 1394 Bus and RS422 Bus is needed in order to achieve the communication between 1394 Bus and RS422 Bus. Designed and implemented the 1394 Bus and RS422 Bus bridge based on FPGA technology. Through the practice of argumentation, under certain conditions, the 1394 Bus and RS422 Bus can be a normal, stable communication. Mainly introduce the designing of bus bridge between 1394 Bus and RS422 Bus in logic structure and data flow.
