摘要
基于Intel Cyclone Ⅳ系列EP4CGX110CF23I7 FPGA芯片在Quartus16.0环境下采用逻辑设计,利用SOPC技术将NIOS软核和外围电路集成到FPGA内,实现控制器与CPU及IO卡收发8路RS-485高速串行通信信号,最大数据收发速率不低于1Mbps,支持电压监控、多信号灯控制功能,PCI和UART接口通信设计,控制器实时时钟、中断和精准时钟对时等功能。
Based on Intel Cyclone Ⅳ series EP4 CGX110 CF23 I7 FPGA chip in quartus16.0 environment using logic design using SOPC technology to integrate the NIOS soft core and peripheral circuits into the FPGA to achieve the controller,CPU and IO card to send and receive 8 RS-485 high speed serial communication signals.The maximum data transmission rate is not less than 1 Mbps,supporting voltage monitoring,multi-signal control functions,PCI and UART interface communication design,controller real-time clock,interrupt and precise clock timing and other functions.
