摘　　要：由于嵌入式安全关键系统自身的特点和应用环境的特殊性,导致了设计嵌入式安全关键应用比一般的嵌入式实时应用要困难得多。在分析传统嵌入式实时中间件技术应用于嵌入式安全关键系统不足的基础上,提出了一种新的自适应安全关键中间件(ASCM)的设计方法,并对相应的体系结构和关键技术进行了讨论。另外,针对嵌入式安全关键系统运行环境的特殊性,重点讨论了一种端到端的自适应服务质量(QoS)管理机制。Embedded Safety-Critical Systems （ESCS） are those systems whose failure could result in loss of life, significant property damage, or damage to the environment. Because of the nature of ESCS, designing the applications for ESCS is harder than that for distributed real-time embedded systems. In this paper, a muhilevel embedded safety-critical middleware called Adaptive Safety-Critical Middleware （ASCM） was described. ASCM provided related services to ease the development of embedded safety-critical applications. Multi-layer end-to-end adaptive QoS management technology was also presented to satisfy the dynamic and unpredictable mission requirements of ESCS.
