Design and Implementation of 1394 and RS422 Bus

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.
