StarFabric高速总线技术的研究与应用

Research and Application of StarFabric High-speed Bus Technology

在嵌入式多处理器系统互联中,为满足大量实时数据的传输,要求互联总线具备高带宽、低延迟、高可扩展性和高可靠性等特点,导致传统的共享总线方式成为数据交互的瓶颈。该文对比分析当前流行的互联总线技术,研究StarFabric互联技术的特点,包括网络拓扑结构设计和StarFabric软件技术等,设计并实现基于高速总线的简单通信协议。通过实际应用测试验证其具有高带宽、低延迟的特点。

In embedded multiprocessor systems interconnection, the highway demands higher demands to satisfy the large number of real-time data transmission, so the traditional shared bus way becomes the interactive bottlenecks of data. This paper analyzes the popular bus technology, and focuses on the StarFabric interconnect technology features, which includes network topology design and StarFabric software technology. And it designs and realizes a high-speed bus-based simple communication protocol. Practical application proves its characteristics of high bandwidth and low latency.
