摘　　要：随着单芯片上集成处理器内核数量的增加，在支持多核处理器的应用程序方面，核间通信变得更加重要。通过分析多核运行任务特点，根据处理核上运行任务功能的不同，将处理核分成两类：控制核和计算核。根据对核的分类，提出了一种新的核间通信模型，该模型提供了三种不同的通信通道。运用这三条通道，把应用程序的I/O部分从计算核迁移到控制核来提高多核的利用率，实验结果表明该方式有效提高核间协作以及核间通信的效率，提升处理器的利用率。With the increasing number of cores integrated on a single chip, it becomes more important for inter-core communication how to effectively support applications on multi-core processor. This paper analyzes the characteristics of multi-core tasks and classifies processor cores into two categories based on their different functions： control core and computing core. According to the classification, the paper designs a novel inter-core communication mechanism which includes three communication paths. With these paths, the mechanism can improve the utilization of multi-core by migrating the I/O part of application from computing core to control core. Experiment results have proved the efficiency of inter-core communication and cooperation are effectively improved.
