数据驱动片内多核通信结构

Multl-core Communication Based on Data Driven

摘要: 针对当前条件下多核处理器遇到的通信瓶颈问题，设计了一种采用数据驱动机制的片内多核通信结构，该结构包括数据驱动模块和片上路由器。数据驱动模块用来进行数据完备性检测;片上路由器则实现处理器核间的通信及“簇”间通信。在Altera公司的CycloneIII开发板上使用NIOS软核构建了多核系统进行了验证。实验结果表明，本设计可以有效的实现多核片内通信，具有很好的可扩展性。

Abstract: For the bottleneck of multi-core communication in current technology,this paper presents a multi-core communication based on data driven. This architecture consists of Data Driven Module (DDM) and On -chip Router.DDM checks the data completeness of a procedure while On -chip Router provides communication between processor cores or "clusters".This architecture has been verified using the multi -core system constructed with the NIOS of Altera' s CycloneIII. The experiment results show that this architecture can make the communication efficiently and has a good scalability.
