IC設計技術中的IP核互連:隨著IC 設計復雜度的不斷提高，在SoC 中集成的IP 核越來越多，基于片上總線的SOC 設計技術解決了大規模集成電路的設計難點，但是片上總線的應用帶來了可擴展性差、平均通信效率低等問題。近幾年來，將英特網絡中分層互連的思想引入到SOC 設計中IP 核的互連上來，提出了全新的集成電路體系結構片上網絡（NOC），NOC 從多處理體系結構、消除時鐘樹以節省資源、實現并行通信等幾個方面，展示了優于總線結構的本質和特性，成功地解決了SOC 設計中存在的問題。

Abstract：With the improvement of complexity in IC design,IP reuse has become one of
the main solution in SOC design. SOC design technology based on bus has some
disadvantages,such as poor scalability and lower communication efficiency,etc. In recent
years, a new architecture NOC is proposed, in which bus interconnection for chip is replaced
by computer network interconncetion. And it will overcome the disadvantages of SOC design
thoroughly and become a mainstream design technology for the next generation intergrated
circuit.
