【摘要】 三维芯片由于其集成度高、功耗小、性能好等优点成为未来芯片制造的一种趋势,其制造成本问题成为该技术是否有应用前景的关键。分析了三维芯片的制造成本模型,并通过实验数据得到了三维芯片的成本最优划分方式;然后对多核处理器的二维芯片和三维芯片制造成本进行了对比,证明了在核数较大的情况下三维芯片制造成本的优势,说明三维芯片在未来芯片门数越来越多的情况下有很好的应用前景。更多还原

【Abstract】 Merits of three-dimensional(3D) integration offers a technology that meets the requirements of the current trend in many-core processors.However,cost is always the dominant factor of adoption of this new technology.After it implemented introduction of a fabrication cost model which evaluated 2D,homogeneous 3D and heterogeneous 3D architectures in some designs.The fabrication costs of these designs and drawn a conclusion that when the number of gates was large,3D implementations were more and more cost-efficient than the 2D baseline with the increase of gates.更多还原
