串行RapidlO交换技术

摘要

Requirements for high-performance embedded signal processing system inter-connect between chips and chips, boards and boards on bandwidth, cost, flexibility and re-liability have ever-increased, which the tradi- tional interconnect way can＇t meet. In view of this, the networking technologies and switch principle of RapidIO, which is the sole stan-dard for embedded system interconnect, has been researched. After that, a reconfigurable n- etworking solution for distributed parallel processing based on Tsi578 has been designed. T-he system performance proved to be stable and has the ability of static and dynamic rec-onfignrable.%高性能嵌入式信号处理系统对芯片间及板间互联的带宽、成本、灵活性及可靠性的要求不断提高而传统的互联方式无法满足日益增长的性能要求。基于此背景，文中研究了当前嵌入式系统互联唯一的国际标准RapidlO的组网技术及交换原理，给出了一种基于Tsi578芯片的可重构分布式并行处理互联网络的组网方案。经验证，交换模块性能稳定，实现了动态和静态的可重构。
