一种多核远程重构控制器的设计与实现

Design and Implementation of Multi-core Remote Reconfigurable Controller

利用可编程片上系统构建多任务远程可重构控制器。控制器运用非对称多核架构、片上双RAM通信区、多任务相互监控、扩展TFTP服务器等方法,保证控制任务的实时性,实现硬软件的远程重构和故障的自主恢复。基于NIOS Ⅱ,论述系统设计的总体思路和实现方法,在实际的控制系统中进行验证,取得了良好的结果。

This paper constitutes a multi-task remote reconfigurable field controller based on SOPC technology.By using the methods of asymmetric multi-core architecture,on-chip dual RAM communications areas,mutual monitor between multi-tasks and extended TFTP server,the controller ensures the operation of real-time tasks.The controller also achieves remote reconfiguration of hardware and software and failure self-recovery.It describes the overall design and implementation method of this multi-core reconfigurable controller based on NIOS II.It has been verified in the actual control system and very good results are obtained.
