摘　　要：由处理器从单核向多核发展及多核处理器从同构向异构发展两个角度,分析处理器的发展历程,阐述导致处理器从单核向多核发展的两个关键问题。通过对同构多核处理器与异构多核处理器的结构特征、性能特点和典型代表的分析,总结处理器向异构多核的方向发展的趋势;对多核处理器核间通信、任务调度、Cache一致性、核间同步与互斥、核间中断处理机制这五大关键技术进行分析;提出当前多核处理器技术面临的三大问题。Processors have developed from single-core to multi-core and so did multi-core processors from homogeneous to heterogeneous.From these two angles,the development trend of multi-core processor was analyzed and two key questions for why processors develop from single-core to multi-core were elaborated.Through analyzing the structure characteristics,performance characteristics and typical representatives of homogeneous multi-core processors and heterogeneous multi-core processors,the development trend of the processor was summarized.The five key technologies of multi-core processor,such as inter core communication,task scheduling,Cache consistency,inter core synchronization and mutual exclusion as well as interrupt mechanism,were analyzed.Three major issues that the current multi-core processor technology faces were raised.
