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。 Multi-display output system is an important part of embedded system design. Building a multi-display output system that provides a simulation environment is crucial to accelerate the development and debugging of end systems. In this paper, the design and implementation of multi-display output system based on single-frame buffer are given in combination with the development practice. The design of single-frame multi-LCD output system based on single hardware is given in order to debug the application. Based on the development experience of TI Omap and embedded Linux, this paper gives the system design and discusses the corresponding implementation technologies.
