| 摘 要： | 异步电路设计方法是现在集成电路研究的热点,得到越来越多的研究人员的关注。在异步电路设计过程中对异步流水线进行性能分析对异步电路的设计过程有着重要的指导意义,但现阶段缺乏有效的方法对异步流水线(尤其是复杂的非线性流水线)进行性能分析。而排队网络是一种能直观地对异步流水线进行建模的数学工具,但排队网络(尤其是复杂的非线性排队网络)的分析求解十分困难。本文提出了一种采用带Fork和Join的阻塞排队网络对异步流水线进行建模,采用其排队网络模型的平均周期作为异步电路的性能评价指标,并通过将其转化为等价的随机标记图对其平均周期进行分析,并给出了其平均周期的上限和下限。

| Abstract: | It is very important to analyse the performance of the asynchronous pipeline during the design of the asynchronous circuit.But there is no very efficient way to evaluate the performance of the complex non-linear asynchronous pipeline.The queuing network is a very intuitive tool to model the asynchronous pipeline,and a performance model of the asynchronous pipeline based on the fork-join queuing network with blocks has been introduced in this paper,then an equivalent stochastic marked graph has also been int... |
