[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.
