就长寿命应用来说,计算系统功能模块采用交叉连接和部件备份的冗余概念预示。它比采用相同硬件的其它形式冗余概念有较高的可靠性.但多故障的容错限度仍不能达到百分之百.由模块式电源、处理机、输入/输出部件和小存貯块组成的功能模块以级备份,装入一共用的箱体内.这种使用现有模块的动态冗余技术会产生一种重量轻、体积小而可靠性高的计算系统.采用简单的模形把这种内部冗余概率预示与外部形式和门级形式的冗余结构相比较.
For long-life applications, computing system functional modules use redundant concepts of cross-connect and part backup predictions. It is more reliable than other forms of redundancy that use the same hardware, but the fault tolerance of multiple faults still can not reach 100%. The functional modules consisting of a modular power supply, processor, I / O components and small memory blocks This is a dynamic, redundant technology that uses existing modules to create a lightweight, small, and highly reliable computing system that uses a simple form factor to integrate this internal redundancy The residual probability prediction is compared with the redundancy structure of external form and gate-level form.
