摘　　要：采用NiosⅡ嵌入式软核构建液晶屏的驱动的解决方案。在FPGA片上系统中调用嵌入式处理器NiosⅡ软核等需要的IP核构建出TFT-LCD控制器,IP核参数化,可以根据不同LCD屏进行配置;利用C/C++语言进行软件设计和开发,实现图片数据同步、像素数据转换、缓存、数据传输及图像显示。用SignalTapⅡ逻辑分析仪对TFT-LCD控制器进行仿真验证。测试结果显示,所设计的TFT-LCD控制器很好的实现对TFT-LCD的控制,图片显示清晰;该设计方法简便快捷,设计的控制器可以适用于多种型号液晶屏。Against the driver differences of different model of LCD,a design method based on Nios It embedded soft core is proposed. The design builts required IP cores such as TFT-LCD controller and Nios It embedded soft core in FPGA. By setting parameters of the IP core,it can be added to the SPOC system easily. The C/C＋＋ language for software design and development. It achieves the image data synchronization, transfer, cache, transmission of the pixels and image dispaly. The design uses the SignalTap II logic analyzer to simulate the TFI＇-LCD controller. The test results show that the designed LCD controller achieves good control of the TFrF-LCD, and has clear graphic display. This design method is simple and quick manipulation and has better code portability and wide applicability.
