基于国产FPGA的以太网远程升级控制器的设计实现

Design and Implementation of Ethernet Remote Upgrade Controller Based on Domestic FPGA

传统FPGA通常采用厂商提供的下载工具进行程序的固化或更新,程序下载时间长,需线缆连接,效率低下。鉴于此,提出一种基于以太网的FPGA远程升级方案,设计了一种并行加载方式的Nor Flash控制器,通过实验验证,该控制器符合设计需求。

Traditional FPGA usually uses the download tools provided by manufacturers to solidify or update the program,which takes a long time to download,requires cable links,and is inefficient.In view of this,a remote upgrade scheme of FPGA based on Ethernet is proposed,and a parallel loading mode of Nor Flash controller is designed.Experiments have verified that the controller meets the design requirements.
