摘要
通过归纳高可靠嵌入式计算机系统的技术特征,分析高可靠嵌入式计算机系统的实现途径,对高可靠嵌入式计算系统的演进进行了系统论述,分别从基础可靠性、系统可用性、系统完整性和系统可信性等技术途径详细地分析了高可靠计算机系统的发展思路,并结合高可靠技术的发展趋势,提出了涵盖完整性等级、容错范围和余度范围等3个维度的高可信嵌入式计算机体系架构,以使人们对高可靠嵌入式计算机系统的认识更加清晰,从而把握高可靠嵌入式计算机系统发展的要点。
The technical features and implement methods of dependable embedded computers were concluded and analyzed, of which the evolution was systemically described. The development process was depicted by four phases, the basic reliability, the system availability, the system integrity and the system dependability. Based on the trend of dependable technology, the dependable computer architecture was proposed with three dimensions, integrity level, fault-tolerant scope and redundancy scope, in order to emphasize the key technologies in the safety critical domain.
