摘要
采用ARM和DSP构建了数据处理系统的基本框架,介绍了系统中嵌入式部分硬件电路设计的方案,给出了硬件连接图,对ARM和DSP之间的数据通信驱动和ARM+Linux环境下的LCD显示驱动的设计进行了介绍,就嵌入式系统启动过程中的显示器花屏和系统运行中屏幕抖动问题进行了探讨,对图像重影和色偏进行了合理的解释并提出了相应的解决方案。
This paper build a basic framework of data processing system based on ARM and DSP,introduction the designe of hardware circuit of the embedded system in this data processing system,Hardware connection diagram is given by author. Introduced the driver of data communication of ARM and DSP and the driver of display for LCD in the environment of ARM and Linux,Discussed the confusion and jitter of the screen in the proceesing of Boot-Up,Gived a reasonable explanation for ghosting of images and color cast,and then proposed corresponding solutions.
