摘要： 基于NIOS II为核心的可编程片上系统(SOPC)，设计可重构的SOPC硬件配置和控制软核，将简单文件传输协议服务器扩展为专门的传输写入服务器，完成远程在线导入多个SOPC硬件配置和控制软核，并制定硬软件远程切换流程，从而实现基于FPGA3C25的多策略控制器设计。在大型望远镜控制系统中的成功应用验证了该设计的可行性。

Abstract: This paper is based on NIOS II as the core of the System On a Programmable Chip(SOPC), designs the reconfigurable hardware configuration and control software core. It extends Trivial File Transfer Protocol(TFTP) server into a special transmitting and writing server to establish the method which may introduce multiple hardware configuration and software core on line, and builds a flow which may realize remote optional switch for hardware and software to achieve multi-strategy controller. Then, multi-strategy controller based on FPGA3C25 is realized. This design is verified in the control system for a large size telescope.

Key words: System On a Programmable Chip(SOPC), Field Programmable Gate Array(FPGA), NIOS II soft core, multi-strategy controller
