【摘要】:為實(shí)現(xiàn)PC輸出在LCD原屏上的顯示,設(shè)計(jì)了一種基于FPGA的LCD控制器,采用IP核搭建系統(tǒng)的框架,系統(tǒng)核心控制CPU采用了Xilinx的Micro Blaze軟核,系統(tǒng)對外通信通過串口實(shí)現(xiàn);通過Xilinx的集成邏輯分析儀IP核ILA在線采集輸入、中間以及輸出數(shù)據(jù),驗(yàn)證系統(tǒng)的可行性及數(shù)據(jù)處理的正確性;最終的實(shí)驗(yàn)結(jié)果表明,所設(shè)計(jì)的控制器能夠驅(qū)動LCD原屏,并且支持多種接口的視頻輸入,顯示畫面穩(wěn)定,同時(shí)實(shí)現(xiàn)了兩路視頻的畫中畫顯示,并可作為PC輸出設(shè)備及視頻監(jiān)視設(shè)備。
[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.
