摘　　要：NoC的设计空间非常庞大,并且不同方案间存在巨大的性能差异,所以在设计初期对不同的设计方案进行性能评价极其重要。以基于建模的NoC性能评价方法为主线,重点分析和对比基于仿真模型和基于分析模型的性能评价方法的研究现状和评价能力,由此归纳出NoC评价模型的准确度评估方法。最后,在对面临的挑战进行分析的基础上,提出基于建模的NoC性能评价的发展方向。The entire design space is extremely large,and there is huge difference of performance between different options.So performance evaluation of different design becomes an important issue in initial stages.The paper took mode-ling-based performance evaluation methodology as masterstroke,discussed research status and metrics of evaluation methods which include simulation modeling and analysis modeling,and summarized accuracy estimating methods of NoC evaluation models.Also,a comparison was made between methods mentioned above.Finally,a guidance of future research was proposed based on the analysis of future challenges.
