摘要: 讨论并参考了冷却储存环目前使用的专用微控制器的特点和其对微控制器的需求，采用可编程技术和Nios-Ⅱ处理器，在altera-cycloneII2c35f484芯片内实现可重构微控制器。该微控制器硬件资源消耗少，最大工作频率可达185 MHz，可代替目前在监控系统中大量使用的专用微控制器芯片，减小硬件设计复杂度、节约成本。Abstract: FPGA and dedicated micro-controller chips are widely used in HIRFL-CSR monitor and control systems.This paper discusses the characteristics of HIRFL-CSR’s dedicated micro-controllers and it’s requirement for micro-controllers. Using programmable technology and Nios-Ⅱ processor, we have designed and implemented a reconfigurable embedded micro（controller in altera cycloneⅡ2c35f484 FPGA. The micro-controller which has low hardware cost and 185 MHz maximum operating frequency can replace the dedicated micro-controller chips, decrease complexity of hardware design and save costs.
