摘要
在航空器、汽车等很多需要高可靠性计算的系统中,通常采用余度技术。随着余度系统带来的功耗、体积、重量、管理等方面的问题越来越严重,要求处理器达到很高的可靠性以降低系统余度。Lockstep处理器架构能够迅速监测处理器运行的错误,进行故障隔离,防止故障蔓延,在处理器级实现高可靠性。进而,Lockstep处理器架构作为新型高可靠计算系统的关键技术,可以实现信息处理的高完整性和高可用性。对Lockstep技术进行分析研究并进行设计实现,实现一种高可靠、高可用的计算处理架构。
The high- reliable computing system in the vehicles improves the reliability by the technique of redundancies. As the problem of power,weight,size and management in the redundancies system becomes more and more serious,it needs to use the high- reliability processor to reduce the redundancies for solving the problem. The architecture of lockstep processing system can detect the fault between the processor and isolate the fault rapidly,which improves the reliability. Furthermore the lockstep system can reach the high- availability as the key technique of new computing system. This paper researches the technique of lockstep system and describes a lockstep architecture to perform the high- reliable and high- available processing system.
