Description

technical field [0001] The invention relates to a communication system in the technical field of wired transmission, in particular to an IEEE1394 bus high-speed data communication interface card. Background technique [0002] With the rapid development of computer technology, various buses emerge in endlessly. There are already many kinds of buses and interfaces, such as PCI bus, RS232 interface and USB interface. Compared with other buses and interfaces, the IEEE1394 bus supports high-speed transmission, is more convenient to use, can be upgraded, can be independent of the host computer, and supports point-to-point connections. It can be used as a unified interface standard, so that various modules that form a system but use different backplane environments can work together and communicate with each other, thereby improving the overall performance of the system. At present, many industrial equipment and household appliances do not have IEEE1394 interface, and cannot enjo...
