With the development of the VLSI technology and semiconductor manufacturing process,multi-core processors have replaced single-core processor. When the development of the technology and technics make the number of core increases, interconnection and communication between each processor core will become choke point to improve the performance of processor. In order to give full play to high-performance of multi-core processors,based on the interconnection of today's mainstream method of multi-core processors,by analyzing the advantages and disadvantages of interconnection method,for different number and structure are introduced the different interconnection methods,that the new materials,new technologies,new devices combined with existing mature mode of interconnection for multi-core is the effective method to improve the efficience of interconnection for multi-core,and the direction of research,the trends of interconnection for multi-core in future is presented.%随着VLSI技术和半导体制造工艺的不断发展,多核处理器已经取代了单核处理器.当技术和工艺的发展使片上多处理器中核的数目增加时,各个处理器核之间的互连及其通信就成为制约处理器性能提高的瓶颈.为了能够充分发挥多核处理器的高性能,文中根据当今主流多核处理器的互连方法,通过分析各种互连方法的优势与不足,提出了针对不同的核的数目和结构采用不同的互连方法,指出将新材料、新技术、新器件与已有的成熟的多核互连方式相结合是提高多核互连效率的有效方法,并阐述了未来多核互连的研究方向和发展趋势.
