摘　　要：工作负载特征模型在计算机体系结构设计和系统性能评价中具有重要作用,有效的工作负载行为特征分析有助于体系结构性能评价和设计改进。通过基于指令级的工作负载特征描述,提取影响测试程序运行时间的关键因素。设计一个负载特征模型,该模型可以根据不同的参数设置生成不同合成工作负载。Workload characteristic model is important in the design of computer architecture and system performance evaluation. Accurate characteristics analysis of workload behavior can help to evaluate the performance of architecture and improve its design. This paper describes the workload characteristics based on instruction level and distills the factors which influence the run time mostly. It designs a workload characteristic model which can generate different kinds of synthetic workload by adjusting the parameters.
