摘要
急迫性和时限是实时处理系统的两个重要特征。本文介绍基于这两个特征而设计的数据冲突分解协议及其性能评估,初步分析结果表明,急迫性和时限的分布情况以及相应的数据冲突分解协议对实时处理系统的性能有重要影响。
Criticality and deadline are two independent characteristics of real-time transactions.Based on these characteristics,this paper introduces a conflict resolution protocol and evaluates its performance.The results indicate that the criticality and deadline distribution strongly affects transaction performance and the conflict resolution protocol can have a substantial impact on the performance.
