摘　　要：设计并实现一种新的MVB总线网关。通过分析MVB ESD+和MVB EMD总线的物理波形差异和网关时延指标要求,使用FPGA在物理层实现波形的高效双向转换,解决ESD+和EMD总线的互联问题。网关普适性好,即插即用,无需进行复杂的端口配置。测试结果表明所设计网关完全满足指标要求。In this paper,a new MVB bus gateway is designed and implemented.By analyzing the physical waveform diff erences 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 effi cient bidirectional conversion of waveforms at the physical layer.The gateway is universal,plug-and-play,and does not require complex port confi guration.The test results show that the designed gateway fully meets the specifi cation requirements.
