基于ARM和FPGA的时间同步仪控制单元设计

摘要

以时间同步仪的功能为出发点,设计了基于ARM和FPGA的控制系统,该系统以ARM芯片S3C2440A为控制核心,在FPGA芯片XCS30的辅助控制下,完成了时间同步仪系统的人机交互、参数设定、电文处理、远程控制等功能。通过键盘操作,LED灯和LCD显示屏,实现了简洁的人机交互控制界面,并在人机交互模块的基础上完成了参数设定模块的设计。通过以太网控制器实现了电文处理,采用CRC校验法,在处理过程中对电文进行检验,确保电文处理的安全可靠,利用Telnet服务器实现了远程控制模块。%This paper presents the design of main control unit of time synchronization system.We have designed main control unit based on ARM and FPGA.S3C2440A is selected as the core control module of main control unit;FPGA is selected as an auxiliary control unit.We have completed the functions of human computer interaction,the parameter settings,message handling and remote control.This paper has researched the mode of human computer interaction,and completed concise HCI as keyboard control,LED and LCD display;We complete the parameter settings based on the mode of human computer interaction;messages are transported by the Ethernet and the CRC checkout is used to checking the messages in the transmission to keep the message transport safety;and the mode of remote control is completed by Telnet.
