【摘要】 随着嵌入式计算机的应用越来越广,对嵌入式系统的可靠性要求也越来越高,嵌入式可信计算机应运而生。针对可信计算机的功能需求,本文研究了容错与嵌入式可信计算机的相关概念和技术,提出了三模冗余+单模热备份的3+1混合冗余结构,进而完成了基于该结构的系统管理板的研究与设计。实验表明该管理板能够有效地管理系统中的计算模块、电源模块及I/O模块,并实现了表决功能、系统重构、热插拔等多项技术。
【Abstract】 With the wider applications of embedded computer, the higher reliability of embedded system is required and the Embedded Dependable Computers came into reality.The paper analyzes the relevant concepts and technology of fault-tolerant and embedded dependable computer firstly,and then presents a 3+1 hybrid redundant structure of triple modular redundancy and single-mode hot backup,and finishes the research and design of system management board which based on this structure finally.Experiments show that this management board can manage the computation module,power supply module and I/O module of the system effectively,and it also realizes several technologies such as the voting functions,system reconstruction,hot swaps and etc.
