摘要
交叉通道数据链路是机载容错计算机系统中很重要的数据交换方式,其可靠性和传输速率影响整个系统的容错性能。该文在核心处理机应用背景下,从编码方式,同步机制,差错控制和数据传输等角度进行分析对比,并设计出基于FPGA和MAX3491驱动器的一种高可靠性的高速交叉通道数据链路(CCDL)。
Cross Channel Date Link is an important way of information exchange in the aircraft fault tolerant control computer.The reliability and transmission rate of it affect the whole system's performance. We analyzed the method of coding, synchronization, fault tolerant control and information exchange under the application of center process computer. At last, we designed a high speed and strong reliability Cross Channel Date Link base on FPGA and MAX3491.
