Seamless Reconstruction Method for TMR Computer Based on Micro-package Protocol
Yuanyuan Shang · 2009
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 standar-dized middleware,which enhances the system's expanding capability greatly.This will lay good foundation of constructing standardized kernel of embedded TMR fault-tolerant computer.
