摘要:
针对传统差分信号网络中继器不具备编解码能力,无法实现对MVB 帧的特殊控制,提出一种基于 FPGA 的MVB 中继器设计方案。详细分析了中继器解码器和编码器的设计过程,包括时延分析和计算、超长帧的判断和截断、帧间隔调整的时延整定与实现等方面的具体设计。通过实际测试,对时间参数进行分析对比,验证了设计的可行性。
Abstract:
Since the traditional differential signal network repeater did not have the ability to codec and was unable to realize the special control of the MVB frames, a design of MVB repeater based on FPGA was put forward. The design processes of the repeater’s decoder and encoder were analyzed in detail, including the repeater time delay analysis and calculation, the judgment and truncation of super-long MVB frames, the time delay setting and implementation of the interframe spacing adjustment, etc. Through the actual test and the comparative analysis of time parameter, the feasibility of the design was verified.
