摘　　要：在可重构计算芯片设计初期,确定芯片的各种互连资源数目是一个关键问题。如果设计的互连资源过少,可能导致应用领域中的部分算法无法实现,而过多的互连资源会造成芯片面积的浪费。基于可重构计算的特点,分析了可重构计算的相邻连接、路由连接和近邻连接三种类型互连资源。通过建立互连资源估计的随机模型,提出了可重构计算芯片中各种互连资源数目的估计方法。仿真结果表明,该方法能够比较准确地估计各种互连资源的数目,从而指导可重构计算互连资源的设计,降低设计风险。It is an important issue to determine the number of each connecting resource for reconfigurable computing（RC） in early design stage.If the number of connecting resource contained in RC is too small,it may result in failure of executing some application algorithms.On the other hand,too much connecting resource may waste chip area.According to characteristic of RC,three connecting resource,neighbor to neighbor connection,routing connection and near neighbor connection are analyzed.By establishing stochastic model for connecting resource estimation,an approach to estimate the number of connecting resource for RC is presented.Simulation result shows that it is a guider to connecting resource design for RC,and is helpful to reduce design risk.
