基于AVALON总线的通用LCD控制组件的设计与实现

Design and Implementation of Universal LCD Controller Based on AVALON Bus

介绍了一种针对TFT-LCD液晶显示屏的通用控制器的设计过程。其方法是以Altera的NiosII处理器为核心,通过发起Avalon主端口的操作,能够完成对帧缓存的读取。本控制器以参数化概念设计,集成在GPS数据接收系统中。实践表明,该控制器运行稳定,并且易于移植到其他SOPC系统中。

This thesis introduces a designing method of a universal LCD controller for TFT-LCD liquid crystal display.With the Altcra Nios II as the core,frame buffer reading process is implemented by launching operation from Avalon master port.The controller designed in the concept of parametric,which can be integrated in GPS data receiving systems.Practices prove that the controller works stably,and is easy to be transplanted to other SOPC systems.
