摘　　要：提出了一种基于微包传输协议的系统重构算法,制定了系统重构命令协议,设计了关键数据区的一致性管理算法。不需增加额外的硬件资源和系统开销,利用三机之间的数据交换通道,即可实现三模冗余容错计算机的无缝重构,保证系统在故障恢复重构时工作的连续性。同时,完善的重构命令协议使得重构软件的开发可以采用面向对象思想构成标准化的中间件,具有很强的扩展能力,为构建标准化嵌入式三模冗余容错计算机内核奠定了良好的技术基础。This paper presented a system reconstruction algorithm based on micro-package protocol. It formulated the system reconstruction command protocol and designed a consistency management algorithm of the key data area. The seamless reconstruction of TMR fault-tolerant computer was implemented through data exchange channels among the three computers without any additional hardware resources and system overhead, which ensures the continuity of system operation during the period of fault recovery and system reconstruction. Meanwhile, due to the perfect reconstruction command protocol, the development of the reconstruction software can use object-oriented method to constitute standardized middleware, which enhances the system＇s expanding capability greatly. This will lay good foundation of constructing standardized kernel of embedded TMR fault-tolerant computer.
