基于FPGA的M4K块配置ROM字符数据存储VGA显示

Stored character data of VGA display based on FPGA M4K block configuration ROM

为了克服通用VGA控制系统核心体系结构不易修改的问题,设计并实现了一种基于FPGA显示控制系统。采用Altera的CycloneⅡEP2C5Q208C8为核心控制芯片,用Verilog HDL语言实现了各个模块,并利用FPGA内部的RAM实现了VGA对汉字的显示。设计结果表明,图像和彩带信号以及文字能由FPGA处理器控制、显示。

To overcome the disadvantage that it is not easy to modify the core structure in traditional VGA control system,the study designed and implemented a FPGA display control system based on Altera chip. The CycloneⅡ EP2C5Q208C8 is used as the core control chip,and Verilog HDL language is used to work out each module. And RAM in FPGA is used to get VGA display of Chinese characters. The test results show that the image and text signals and ribbons can be controlled and displayed by FPGA processor.
