多核处理器核间高速通讯架构的研究

Research of High Speed Communication Architecture about Inter-core of Multi-core Processors

多核处理器使得并行系统的结构日益复杂,已经成为处理器的主流,并发展成为各种通信与媒体应用的主流处理平台。通讯结构是多核系统中的核心技术之一,核间通信的效率是影响多核处理器性能的重要指标。目前有三种主要的通讯架构:总线系统结构、交叉开关网络和片上网络。总线结构设计相对方便、硬件消耗较少、成本较低,交叉开关是适用于构建大容量系统的交换网络结构,而片上网络是更高层次、更大规模的片上网络系统,目前可以彻底解决多核体系结构问题,是多核系统最有前途的解决方案之一。论文较为详细地分析了这三种结构的基本原理、系统结构和功能,提供了部分单元的设计实现。

In recent years,multi-core architectures have been the mainstream design of the processors as well as the mainstream processing platform of various communication and multimedia applications,and make the architecture of parallel system more and more complex.Communication structure becomes one of the core technology of multi-core processors,the efficiency of communication between the inter-core is the key indicators of multi-core processor performance.There are three main types of communication architecture：Bus system,cross-bar network and on-chip Network.Bus structure designs convenience,low hardware consumption and low cost.Cross-bar suitable for switching network structure of building large-capacity system.On-chip network is higher level,larger on-chip network,which can completely solve the problem of Multi-core architecture,and becomes one of the most promising solutions of multi-core system.The paper discusses three communication architectures about Principle,system structure and function at the same time provides realizations of some units.
