Design and Implementation of a 1394 Bus Emulation Card with High-Speed Optical Interface Module

With the rapid development of multimedia technologies, high-speed data acquisition, and real-time processing applications, the demand for greater data transmission bandwidth and lower latency has significantly increased. The IEEE 1394 bus (also known as FireWire or i.LINK), with its high bandwidth, low latency, and hot-plugging capabilities, has been widely adopted in fields such as industrial control and audio-video transmission. However, traditional 1394 buses rely on copper cable transmission, whose bandwidth and transmission distance are inherently limited by electrical signal characteristics, making them unsuitable for ultra-high-speed and long-distance data communication. To address these limitations, this paper proposes the design and implementation of a 1394 bus emulation card equipped with a high-speed optical interface module. By leveraging optoelectronic conversion techniques, the system enhances the performance of the bus. Furthermore, the core protocol emulation and data processing functionalities are implemented on an FPGA platform, enabling broader applicability of the 1394 bus in high-speed data communication scenarios.
