摘　　要：不同领域的嵌入式计算机的性能评估有很大的差异性,对分布式嵌入式计算机的性能评估需要考虑其自身特点。分析了分布式嵌入式计算机的一般特征,提出了一种结合软硬件的、面向分布式嵌入式计算机的性能评估模型。该评估模型从分布式嵌入式计算机的通用技术特征方面入手,提出了度量系统性能的指标和评估准则,具有指标定义明确、评价过程简便等优点。总结了几种常见的综合评价方法,为分布式嵌入式计算机的性能评估定义了完整的综合评价过程。通过实验表明了该方法的可行性。该研究对分布式计算机系统的体系结构设计、性能分析与改进具有重大的意义。There exists great difference in performance evaluation of embedded computer in various application domains.The distributed embedded computer has its characters which should be taken into account while they are evaluated.The general characteristics of distributed embedded computer were analyzed,and a performance evaluation model was provided for the distributed embedded computer in view of its HW ＆ SW.Starting with the common technology characteristics of distributed embedded computer,the model contains metrics and guidelines,which builds up an integrated evaluation model and takes advantages of explicit definitions and convenient regulations.Several common synthetic evaluation processes were summarized and on this basis a complete synthetic evaluation process was provided specially for the distributed embedded computer.The method is of good feasibility by an experiment.The study has great importance for performance evaluation of embedded devices,especially for distributed systems and the related design.
