【Abstract】 With the development of the information technology and the computer communication technology, the information transmission equipment is widely used in production and scientific research. Facing to the development of the information collection system, the traditional information transmission equipment has been unable to meet people’s needs. In this paper, aiming at the shortages of the traditional information transmission equipment, such as slow data transmission speed, bad real-time capability and low versatility, a design plan of the IEEE1394 high-speed information transmission between the computer and the peripherals has been brought forward.According to the research topics, specific design has been put forward. Analyzing the 1394 bus technology and according to the different characteristics of the different chips, the 1394 chips which meet the design requirements have been chosen. Then, the micro-controller chip will be selected. The 1394 link layer chip can be linked to the physical layer, and then the 1394 chips can complete the task of transmission. Connect to the micro-controller chip and the 1394 link layer chip, and then the controller can initialize the 1394 chips and deploy the 1394 bus. Next, connect the data processer to the micro-controller and the 1394 transmission parts, and make the design of the anti-interference. The design of the software includes the design of the 1394 node program, which makes the 1394 part to prepare to the transmission; the design of the interrupt service program, which makes the system to handle different types of the interrupt request; the design of the data transmission program, which makes the equipment to complete the high-speed information transmission.The subject based on the technical features of the IEEE1394 bus, it can improve the transmission speed, the real-time capability and the versatility of the equipment. Making the device hardware detection and on-line debugging, the hardware test results show that the equipment’s hardware is working correctly, and the software test results show that the equipment has the ability of the asynchronous and the isochronous transfer functions, which achieved the target topic.更多还原
