摘要

为解决多输入格式视频在同一LCD上显示的问题，设计了一种基于IP核的支持多种视频输入接口的LCD控制器。采用IP核产品搭建系统的框架，系统核心控制CPU采用了Xilinx的MicroBlaze软核，以控制各IP核的初始化以及工作方式，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，本文设计的基于IP核的多接口LCD控制器能够驱动LCD原屏，并且能够支持多种接口的视频输入，显示画面稳定，满足作为PC输出设备及其他接口视频监视设备的要求。

Abstract

In order to solve problem of displaying different kinds of input video on LCD

an LCD controller based on FPGA which supports different kinds of video is designed. The system frame is formed of different IP cores. The system CPU is Xilinx Microblaze soft core

which is used to control the IP core. The communication between PC and microblaze use the UART core. In order to survey the signals in the FPGA to identify the logic

the Xilinx integrated logic analyser IP core ILA is used to survey the critical signals. The result shows that the designed LCD controller based on IP core can drive the LCD

the system supports several video ports. The displaying picture is stable

which can be used as PC displaying device or displaying other videos.
