摘要： 为实现总线多通道数据并发高速传输与容错，解决故障状态下的总线数据动态重构问题，设计一种动态可重构总线数据传输管理方法。采用四体先入先出队列(FIFO)进行数据缓冲存储，利用通道故障状态表，通过4×32矩阵开关数据，传输管理阵列组织与4个FIFO缓冲区及所有有效通道间的数据传输。在8通道系统中的实验结果表明，最高通信速率可达到800 Mb/s，能对7个通道故障进行动态容错。

Abstract: In order to meet the needs of high-speed multi-channel data transmission and fault-tolerant, this paper puts forward a kind of data transmission management method. Using four-body First Input First Output(FIFO) for data buffering and a channel list for recording the fault state together with a 4×32 matrix switch array, the data transmission between the four-body FIFO and all valid data transmission channel can be organized and managed efficiently. Experimental result in the 8-channel system shows that the maximum communication rate is up to 800 Mb/s, and 7 channels can achieve fault tolerant dynamically.

Key words: high-speed serial bus, fault tolerance, dynamic reconfiguration, concurrent transmission, matrix switch
