【摘要】：为实现PC输出在LCD原屏上的显示,设计了一种基于FPGA的LCD控制器,采用IP核搭建系统的框架,系统核心控制CPU采用了Xilinx的Micro Blaze软核,系统对外通信通过串口实现;通过Xilinx的集成逻辑分析仪IP核ILA在线采集输入、中间以及输出数据,验证系统的可行性及数据处理的正确性;最终的实验结果表明,所设计的控制器能够驱动LCD原屏,并且支持多种接口的视频输入,显示画面稳定,同时实现了两路视频的画中画显示,并可作为PC输出设备及视频监视设备。
[Abstract]:In order to realize the display of PC output on LCD screen, an LCD controller based on FPGA is designed. The frame of the system is built with IP core. The core control CPU of the system adopts Micro Blaze soft core of Xilinx, and the external communication of the system is realized through serial port. The input, middle and output data of the IP core ILA of Xilinx integrated logic analyzer are collected online to verify the feasibility of the system and the correctness of the data processing. Finally, the experimental results show that the controller can drive the LCD screen. It also supports the video input of various interfaces, and the display picture is stable. At the same time, it realizes two channels of video in-picture display, and can be used as the PC output device and video monitor device.
