Abstract: This paper describes the design and implementation of single frame buffer multi-displayer system. It is worth while building system with the current single LCD system to simulate a multi-LCD system to give the software a running environment. The design, implementation and technology relative to single frame buffer multi displayer system are discussed base on the development experience with TI Omap and embedded system——Linux.

Key words: Multi-displayer, Single frame buffer, Board support package(BSP), Embedded system, Linux

摘要： 多显示输出系统是嵌入式系统设计的一个重要组成部分。构建多显示输出系统、提供一个仿真环境，对于加速终端系统的开发和调试进程是至关重要的。该文结合开发实践给出了基于单Frame buffer的多显示输出系统的设计和实现，给出了基于单硬件的单Frame buffer多LCD输出系统的仿真系统的设计，以便应用调试。在TI Omap和嵌入式Linux的开发经验的基础上，该文给出了系统设计，讨论了相应的实现技术。
