Abstract: In this paper, a new MVB bus gateway is designed and implemented. By analyzing the physical waveform differences between MVB ESD+ and MVB EMD buses and the gateway latency index requirements, the interconnection problem between ESD+ and EMD buses is solved by using FPGA to realize efficient bidirectional conversion of waveforms at the physical layer. The gateway is universal, plug-and-play, and does not require complex port configuration. The test results show that the designed gateway fully meets the specification requirements.
