摘　　要：体系结构模拟技术在计算机体系结构研究和系统设计中发挥着重要作用.通过对计算机系统的建模、仿真及评估,科研人员可以验证新型体系结构设计;将该技术导入产品设计则可以优化系统方案、降低设计风险并提升开发效率.随着半导体工艺的迅速提升,分布式共享内存计算机系统已步入千核时代,处理器微结构、存储层次、片间互连及cache一致性协议等对系统性能的影响愈发复杂,对体系结构模拟技术也提出更高挑战.本文依据计算机体系结构模拟技术特征,从精度、速度、可用性和易用性四个方面对现有体系结构模拟技术进行了分析、总结.针对计算机系统发展趋势与当前模拟器存在的问题,归纳了体系结构模拟技术面临的挑战,进而提出了未来体系结构模拟技术发展的4A理论.Architecture simulation technology plays a key role in computer architecture research and system design. It can facilitate thevalidation of novel computer architecture design. System vendors can also optimize the design ,reduce the risks, and improve develop-ment efficiency with it. With massive progress of semi-conductor technologies, kilo-core distributed shared memory （DSM） systemwill appear. As the impact of the processor ＇ s micro-architecture, memory hierarchy, interconnection and cache coherence on systemperformance tends to be diverse and complex ,new challenges are brought to the architecture simulation technologies. This paper sum-marizes the characteristics of existing architecture simulation technologies from accuracy, acceleration, availability and adaptability as-pects, and then concludes their challenges in current stage. Considering future computer architecture simulation technologies, a novel4A theory is proposed at the end of paper.
