动态可重构高速串行总线中断请求方法的设计与实现
|
摘要
动态可重构高速串行总线(UM-BUS)具有多通道并发冗余的特征以及远程存储访问能力,然而传统的固定网络结构已不能适应CPS、物联网对异构资源动态接入、多源感知融合的需求.为解决UM-BUS总线网络中功能模块的即插即用和实时响应,本文提出一种低开销、高效率的中断请求与仲裁方法,采用基于编码仲裁的方式实现总线节点设备的中断处理,满足CPS、物联网应用环境下,UM-BUS总线节点设备之间事件中断通知与快速实时响应的需求.
Dynamic reconfigurable high-speed serial bus(UM-BUS)has the characteristics of concurrent lanes redundancy and remote memory accessing capabilities.However,traditional fixed network structure does not meet the requirements of dynamic access and multi-source information fusion for the heterogeneous resources of CPS and Internet of things.To solve the problem of plug and play and real-time response of UM-BUS modules,this paper presents a method of interrupt request and arbitration with low cost and high efficiency.It adopts encoding arbitration to fulfill the interrupt handling of UM-BUS devices.This method can satisfy the requirements of event interrupt notification and real-time response between UM-BUS devices in the CPS or Internet of things application environment.
