Abstract: 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.
