术语 | voting processor |
释义 | voting processor 表决处理机(系统) A method of detecting error occurred in a computer system by executing the same instructions by three or more processors simultaneously.The name “voting” is derived from a comparison technique where, if any result differs, the erring CPU is “voted” out of the configuration. The remaining units then continue to operate until the faulty CPU is repaired. Often a fourth processor is kept on standby in order to replace an erring processor. 检测计算机系统发生错误的一种方法,它利用三个以上的处理器同时执行相同的指令。“表决”这 个词来自一种比较技术,当程序执行的结果不同时,发生错误的CPU就被“否决”出系统配置,剩下的 设备继续运行,直到出错的CPU修复为止。通常还有第四台处理机保持备用,以便替换出错的处理机。 |
