FPGA点阵显示屏的设计

Design of FPGA Dot Matrix Display Screen

基于可编程片上系统(SOPC)技术,设计了一款以FPGA处理器为核心的嵌入式控制系统。将MC8051软IP核及必要的外围IP模块集成在FPGA芯片中,对温度显示和屏幕花样滚动显示进行了重点设计。通过软件代码,极大简化了硬件电路设计,系统稳定性得到了很大提高。

An embedded control system based on SOPC（ programmable system on chip） technology and FPGA processor as core is designed,which integrates the MC8051 soft IP core and the necessary peripheral IP modules in the FPGA chip. This paper focuses on the design of temperature display and screen pattern scrolling display. Through the software,the hardware circuit design has been greatly simplified and system stability has been greatly improved.
